Abstract (en)
[origin: US4731291A] A photographic paper support material for photographic purposes is disclosed with a polyolefin coating on both sides, wherein the base paper is internally sized by using a hydrophobizing sizing agent, and is surface sized with an aqueous coating mixture. The aqueous coating mixture contains a carboxyl-modified polyvinyl alcohol and optionally includes compounds with polyvalent cations. The paper support material is preferably used with such photographic layers as require wet development and wet fixing of the photographic image with photographic processing solutions.
