ABSTRACT:
A photographic support material is disclosed for light sensitive coatings in the form of a plastic coated paper or a plastic foil whose backside has a coating allowing writability. The back coating comprises a terpolymer latex of styrene-butadiene-methacrylate, a hard silicic acid, and an aluminium modified colloidal silicic acid sol. The coating may also include an aqueous solution of a salt of an organic polyacid. The quantities of the additives used result in optimal characteristics of printability, writability using various pens and lead pencils, minimal soiling in old developing baths, minimal coloring in developing solutions, good tape adhesion and, when required, good antistatic characteristics.
