PHOTOGRAPHIC PRINTING MATERIAL

摘要

PURPOSE:To improve the sharpness of an image by disposing a dye or pigment in the hydrophilic colloid layer and synthetic resin film of a photographic printing material having the hydrophilic colloid layer disposed and photosensitive silver halide emulsion layer disposed on one side of the base of a paper base coated thereon with a synthetic resin film. CONSTITUTION:A dye or pigment which is not decolored during a photographic process is incorporated into the hydrophilic colloid layer and/or synthetic resin film of a photographic printing material formed by disposing the hydrophilic colloid layer contg. a white pigment on one surface of a paper base coated with the synthetic resin film on both sides thereof. The dye and pigment to be used have preferably absorption max. at 500-800nm and are enumerated by an inorg. dye such as anthraquinone and azo and inorg. pigment such as ultramarine or the like. The photographic material consisting of the paper base coated thereon with the synthetic resin film and having improved sharpness is thus obtd. by such constitution.
