Claims19
A silver halide color reversal photographic material which comprises a support having on the one side thereof a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer, and on the other side thereof a gelatin-containing backing layer, said backing layer containing a gelatin of an isoelectric point of 5.5 or more and further containing a cationic polymer.
A method of retouching silver halide color reversal photographic materials which comprises developing a silver halide color photographic material comprising a support having on the one side thereof a blue-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer and a red-sensitive silver halide emulsion layer and on the other side thereof a gelatin-containing backing layer said backing layer containing a gelatin of an isoelectric point of 5.5 or more and further containing a cation polymer and then retouching the developed silver halide color photographic material from the side of backing layer thereof by means of water soluble anionic dyes.
