Abstract

1307373 Photographic silver halide emulsion having unhydrolyzed copolymer binder KONISHIROKU PHOTO INDUSTRY CO Ltd 2 Oct 1970 [4 Oct 1969] 47074/70 Heading G2C [Also in Division C3] A light-sensitive silver halide comprises a hydrophilic colloid and an unhydrolyzed copolymer of an alkyl ester of acrylic or methacrylic acid with a vinyl ester as a binder. The acrylic or methacrylic acid ester may be ethyl acrylate, ethyl methacrylate, n-butyl acrylate, n-butyl methacrylate, n-octyl acrylate, n-octyl methacrylate, n-dodecyl acrylate or n-dodecyl methacrylate. The vinyl ester may be an ester of an aliphatic monocarboxylic acid e.g. vinyl butyrate, vinyl propionate, vinyl acetate or vinyl laurate. 10-90% by weight of the copolymer units may be derived from the vinyl ester. The hydrophilic colloid may be gelatin. The emulsion may contain 10-60% by weight of copolymer based on the weight of gelatin. The emulsion may be prepared by copolymerizing in an aqueous emulsion the alkyl ester of acrylic or methacrylic acid and the vinyl ester and mixing the aqueous emulsion obtained with an emulsion of lightsensitive silver halide in the hydrophilic colloid. The emulsion has improved pressure resistance and elements comprising such emulsions have improved resistance to curling.
