PURPOSE:To enable a rapid development processing and to improve processing stability by incorporating a specified rapidly reactive yellow coupler in a blue- sensitive silver halide layer, and another specified magenta coupler in a green- sensitive silver halide layer. CONSTITUTION:A blue-, green-, and red-sensitive silver halide layers are formed on a support. The rapidly reactive yellow coupler having a relative reaction speed of >=0.3 is added to this blue-sensitive layer. The green-sensitive layer contains a pyrazolotriazole type magenta coupler represented by the formula in which R1 is halogen or a group releasable by the coupling reaction, and R2, R3 are each H, alkyl, aryl, heterocyclic, acylamino, alkylamino, anilino, or the like. The addition of the rapidly reactive yellow coupler and the magenta coupler permits development to be executed at high speed, fogging to be restrained, and raw storage stability to be enhanced. |
