Stock: 100% bleached chemical pulp. 

No fluorescent (optical) brighteners shall be added to the 
pulp or paper during manufacture. Fluorescence, due to 
residual white water, broke, or natural fibers, is 
permissible; provided the increase in reflectance, measured 
with and without the ultraviolet component of a light 
source of 3100 Kelvin in combination with a C.I.E. 
(International Commission on Illumination) Z (blue) filter, 
does not exceed 2.0%. 

Note:1 Postconsumer fiber, in any percentage, is 
encouraged, provided that the requirements of this 
Standard are met.
