PURPOSE: To provide the base for photographic paper which has the good smoothness of the surface while having the water resistance and whiteness equal to the water resistance and whiteness of the conventional base and has the high adhesion between a raw paper and a resin coated layer and the durability to peeling by coating the surface of the raw paper with a compsn. essentially consisting of polyethylene terephthalate having excellent surface smoothness.
CONSTITUTION: This base for the photographic paper is constituted by coating the emulsion coating side surface of the raw paper with a compsn. prepd. by mixing and dispersing a white pigment in a resin contg. ≥50%, by weight, the polyethylene terephthalate and coating the other surface with a resin or a compsn. prepd. by mixing and dispersing powder, etc., in the resin. The above- mentioned base contains the resin contg. a polar group in the coating layer on the emulsion coating surface side.
