photographic paper
Paper used as the base for various photosensitive
systems which use silver halide crystals as the
light sensitive receptors. It is a carefully made
paper produced either from cotton fibers or highly
purified chemical wood pulp. The paper must be
free of all substances, especially chemicals,
which might adversely affect later processing and
it must also possess high wet strength so as to
permit processing in both acid and alkaline
solutions. Photographic paper ranges in thickness
from 0.0025 to 0.015 inch. (17 )
