PURPOSE:To obtain the titled material having less tendency for generating a spot by incorporating poly(vinyl crown ether) to a photographic constituting layer. CONSTITUTION:The photographic constituting layer contg. the photosensitive silver halide emulsion layer is mounted on a substrate body, and the poly(vinyl crown ether) is incorporated to at least one layer of the photographic constituting layer. The poly(vinyl crown ether) is exemplified by one or more kinds of a polyvinyl type, a polyacryl anilide type, a polybenzyl acrylate type and a polyalkyl arylate type poly(vinyl crown ether). Said compds. are dissolved to the prescribed solvent, and the obtd. solution of said compds. is added to the photosensitive silver halide emulsion and/or the non-photosensitive solution. Thus, the titled material capable of preventing the generation of the spot, without deteriorating the photographic characteristics, is obtd. |
