<p>PROBLEM TO BE SOLVED: To obtain a photographic printing paper capable of forming a dye image resistant to discoloration and color fading at the time of development processing by interposing at least one oxygen insulating layer between a paper sheet and a biaxially stretched polyolefin sheet. SOLUTION: The biaxially stretched polyolefin sheet is attached to the surface of the paper sheet and at least one oxygen insulating layer having an oxygen permeability <78.954 cm3/m2.h.MPa is interposed between the paper sheet and the biaxially stretched polyolefin sheet. The oxygen insulating layer is made of at least one of a polymer selected from a group of a homopolymer or copolymer of acrylonitrile, alkyl acrylate, and polyester, and cellulose acetate. It is preferred that the oxygen insulating layer is arranged in an interface between the polyolefin sheet and an achesive layer for adhering this sheet to the photographic support.</p> |
