Description
A high grade of paper used for photographic prints. Good photograph paper is made from 100% cotton or linen rags because lignin and other residues react with the photosensitive salts and destroy the image. Photographic paper also has to be strong, uniform, and dimensionally stable when wet and dry. For increased wet-strength, the papers were sized with animal glue, starch, stearic acid, or synthetic resins, such as melamine (used since 1948). One or more fillers, such as barium sulfate, titanium dioxide, clay, starch, or polyacrylamide, are also added for opacity, color, and strength. The papers were calendered to produce a smooth, nonporous surface. Since the late 1960s, most color photographic papers have been made from cellulose fibers coated on both sides with polyethylene.
