1487805 Gelatin composition FUJI PHOTO FILM CO Ltd 17 April 1975 [17 April 1974] 15983/75 Heading C3H [Also in Division G2] A silver halide photographic light-sensitive material has a non-light-sensitive intermediate surface layer or final surface layer containing alkali-processed gelatin having an isoelectric point of a pH of 4À5 to 5À3 and acid-processed gelatin having an isoelectric point of a pH of 6À0 to 9À5, in a ratio by weight of 0À5 to under 100 parts of alkali-processed gelatin per 100 parts of acid-processed gelatin. Other hydrophilic binders can be present in the layers, e.g. enzyme-treated gelatin, modified gelatin or gelatin graft polymers. The intermediate or final surface layer may contain a matting agent, e.g. organic or inorganic particles, less being required than when conventional gelatins are used.
