This class takes the characters of processes set forth below,
the products of such processes where not more specifically provided
for, and in the specified instances, compositions used in the processes.
(Also see References to Other Classes, below.)
This is the generic class for processes of and compositions
for dyeing materials of any kind (subclasses 400-696), including
specific treatments peculiarly related to dyeing, such as mordanting,
weighting, color protecting, etc. In subclasses 400-696 the main
line subclass title indicates whether the particular subclass and
its indents are limited to processes, compositions, etc., or combinations
of such. In instances where subject matter proper for subclasses
400-696 is combined with subject matter proper for other main classes,
unless contraindicated elsewhere, if the dye steps are followed
by subject matter proper for another main class the combination
is classified in the other class and cross-referenced here. Dyeing
steps following or simultaneous with steps proper for other classes
are generally classified here.
This is the generic class for processes of and compositions
for treating hides, skins, feathers and animal tissues with chemicals
and fluids (see References to This Class, below).
This is the generic class for processes of bleaching materials
of any kind (see References to This Class, below).
This is the generic class for processes of and compositions
for improving felting properties of textile fibers, hair, fur, feathers,
etc.,e.g., carroting (see References to This Class, below).
This is the generic class for the chemical modification of
textiles and organic fibers and takes compositions for this purpose
when not more specifically provided for elsewhere e.g., parchmentizing
and mercerizing compositions (see References to This Class, below).
This is also the class for special types of processes for treating
textiles and fibers with fluids even though the fluids do not chemically
modify the textiles and fibers, namely: (a) plasticizing or swelling
of artificial fibers whether or not combined with stretching; (b)
fiber protecting during treatments provided for in this class; (c) color
protecting during treatments provided for in this class); (d) cleaning
and laundering (see References to This Class, below).
Manipulative processes for the treatment of textile fibers
of fabrics, hides, skins and leather with chemicals and fluids for
a purpose provided for in this class which are of general applicability
are placed in this class, even though limited by claim terminology
to a particular treatment, e.g., dyeing, bleaching, tanning, etc.
(See References to This Class, below).
This class has no apparatus, per se, but where a process or
product, classifiable in this class, is claimed along with claims
to apparatus, the patent is placed in this class (8) and cross referenced
to the appropriate apparatus class.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
For coloring of plastic materials by incorporation of coloring
matter in solution or plastic composition before shaping, see the
appropriate classes, e.g., Class 106; Class 252; Class 260; etc.
The printing compositions employed in this class are basically
distinguished from the printing inks of Class 106, Compositions:
Coating or Plastic, in that the latter are intended essentially
for coating the surface of a material in patterns or designs, while
in this class the coloration is produced by imbibition and absorption
by or combination with the fibers of the material. Class 106 usually
involves an insoluble pigment suspended in an oleaginous vehicle,
while here a soluble dye in an aqueous paste is usually involved.
The rules for determining Class placement of the Original
Reference (OR) for claimed chemical compositions are set forth in
the Class Definition of Class 252 in the section LINES WITH OTHER
CLASSES AND WITHIN THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY,
which includes a hierarchical ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.

SECTION V - GLOSSARY
ACID DYE
A dye containing organic acid groups, e.g., sulfonic,
sulfamic, phosphoric, carboxylic, etc., or their salts. Acid dyes
are commonly sodium salts of organic acids applied in an acid bath
and used to dye wool, polyamide and silk. Acid dyes have the ability
to be substantive to substrates with basic groups.
BASIC DYE

e.g., polyacrylonitrile, acid modified polyester, etc. They include
diphenylmethane, triphenylmethane, xanthene, naphtroperinone, quinophthalone, quaternary
ammonium group, etc., containing dyes.

Direct dyes, also known as substantive dyes, are generally
sulfonated azo compounds very similar to acid dyes in constitution,
good for dyeing cellulose fibers or protein fibers.
DISAZO
Disazo for the purpose of this class is define d as a
compound containing two or more azo (-N=N-) groups.
DISPERSE DYE
Disperse dyes are water-insoluble, neutral dyes applied to
the substrate from a fine aqueous suspension, which were originally
developed for use in dyeing of cellulose acetate and polyester materials.
DYE ADDITIVE
A dye additive or assistant is defined to be any material added
to a dye to help in dyeing and is not basically a part of the dye
itself.
DYEING

and accepted meaning in the art, that is to say, it denotes imparting
a substantially permanent color to organic fibrous or filamentous
material or other porous material by the use of substances, or preparations
possessing tincorial properties and which are not dependent for
their ability to become fixed to the base solely upon the presence
of an adhesive of bindive vehicle or ingredient, as distinguished
from the application of an insoluble pigment suspended in a bindive
vehicle, e.g., paint or any colored coating composition where the
coloring agent does not actually color the base.
FUGITIVE TINTING
Denotes the application of a temporary or easily removable
coloration to a material for identification or like purpose.
HETERO ATOM
The hetero atoms are nitrogen, oxygen, sulfur, selenium, and
tellurium.

and which upon combination with the mordant deposit insoluble color
on the substrate, e.g., dyes with metal chelating groups.
MORDANTS
Are substances of organic or inorganic origin which combine
with the coloring matter and are used to fix the same in the production
of the color. For the purpose of this class, such materials as oils
and sulfonated oils, soaps, fats and higher acids, are not generally
considered as mordants, but as coming within the scope of "assistants" in
dyeing.
OXIDATION DYE
Oxidation dyes are dyes which produce a color by oxidation
on the substrate of compounds such as arylamino, hydrxyaryl, or
similar compounds to produce, e.g., aniline black or diphenyl black.
Nitroaniline dyes are included.
REACTIVE DYE

-H atoms thereon, e.g., ester or ether formation with cellulose.
SOLVENT DYE
A solvent dye is a dye which si soluble in an organic solvent
and is commonly introduced in the form of a solution in an organic
solvent.
SULFUR DYE
Sulfur dyes contain sulfur linkages within their molecules
which are produced by sulfurization, i.e., heating of organic compounds
with sulfur or alkali polysulfides.
SUBSTRATE
The term substrate is used here to refer to the base
material being dyed.
TEXTILE MATERIAL
As employed in this classification is limited to organic fibrous
and filamentous materials, and mixed materials including same as
a definite component part thereof and not in the popular sense to
include all materials, e.g., it does not include asbestos and glass
fibers adapted to be felted, woven or knitted not glass fiber fabric.
In the dyeing subclasses (400-696) paper has been grouped with the
textile materials.
VAT DYE
Vat dyes are dyes which are applied to the substrate
in reduced, soluble form and then oxidize to the original insoluble
pigment. Common vat dyes are quinonic dyes and particularly common
are anthraquinones and indigoids.

as "materials") to affect a chemical modification
thereof.
(1)
Note. Subclasses 115.51+ includes processes or products
thereof modifying the chemical or physicochemical properties of "materials",
i.e., the "materials" are acted upon by a chemical
or other agent as distinguished from the mere coating, impregnating,
precipitation of a substance within the "materials" structure which
are classified in Class 427. Excluded from here also are those processes
or products thereof which are concerned with the coating, impregnation
of precipitation by an in situ chemical reaction which does not
chemically involve the substrate "material". Also found
here are those chemical effects on a component normally associated
with a "material", for example, sericin of silk.
(2)
Note. The chemical modification of paper is classified here
because of its similarity to other cellulosic "materials".
(3)
Note. In the case of coating or impregnating processes or
products thereof, where doubt exists as to whether or not a chemical
modification has occurred, the process or product thereof is classified
in Class 427 and generally cross-referenced to this class, subclass
115.51.
(4)
Note. The chemical modification of a substance other than
a textile or fiber with subsequent processing to produce a textile,
fiber, web, etc., is not classified here. For example, the chemical
modification of polyvinyl chloride with subsequent fiber formation
with no claimed structure of characteristics is in Class 525.
(5)
Note. The heat treating of "materials", e.g.,
to produce carbon fiber precursors, is properly classified here
despite the lack of a chemical agent since the chemical nature of
composition of the "material" was altered.
(6)
Note. Patents claiming a product derived from chemically modified "material" are classified
on the basis of the process for chemically modifying the "material".

wholly or in part due to a wave-type energy, electrostatic field
or a field in which electrical discharging occurs.
(1)
Note. This subclass includes processes wherein the chemical
modification occurs solely through the use of the wave energy, electrostatic
field or an electrical discharge. Also found here are those processes
which utilize in additional chemical reactant. For example, a textile

means preventing the formation or development of the color in local areas;
or by modifying the characteristics of selected areas of the material,
so that it does not have the same tinctorial properties as the untreated
parts of the material, as by mercerizing, immunizing, etc. The treated
areas may have their affinity for certain types of dyes decreased
but their receptivity for other types enhanced, as in the case of
immunized or saponified areas, or by the application of so-called
mordant-resists.
(3)
Note. Silk screen printing is considered resist printing.
(4)
Note. In the subclasses hereunder classification is only on
