Abstract

1,216,521. Photographic silver halide colour materials. KONISHIROKU PHOTO INDUSTRY CO. Ltd. March 4, 1968 [March 3, 1967], No.10408/68. Heading G2C. Graininess of the dye image and fog are reduced in photographic silver halide colour materials which contain a colour coupler by incorporating into the emulsion or a contiguous layer (a) an alkalisoluble phenolic compound capable of reducing silver halide and (b) a water-soluble polymeric vinyl compound containing the recurring unit of the formula:- where A completes with the nitrogen and adjacent carbon atom a 5- to 7-membered heterocyclic ring, the polymer being capable of forming a complex with the phenolic compound (b). Phenols (a) specified include hydroquinone, p-aminophenol and p-benzalaminophenol and derivatives thereof. Polymeric vinyl compounds (b) specified are polyvinyl pyrrolidone, polyvinyl oxazolidone, polyvinyl piperidone and polyvinyl caprolactam.
