PURPOSE:To prevent the generation of a fog in an image and to improve the raw shelf stability and the image preservation property of the title material by incorporating a specified cyan coupler and a specified magenta coupler in the sensitive material. CONSTITUTION:The pyrazoloazole type cyan coupler (such as a compd. shown by formula I) having one or more group capable of forming hydrogen bond at a position capable of substitution except an active point of a pyrazoloazole ring is incorporated in a red sensitive silver halide emulsion layer contd. in the sensitive material. Two equivalents of the 5-pyrazolone type magenta coupler (for example, a compd. shown by formula II) is incorporated in a green photosensitive silver halide emulsion layer. In the formula, X is hydrogen atom. or a group capable of being released by allowing it to react with the oxidant of a color developing main agent, Z1 is an atom. group necessary for forming an azole ring, R1 is hydrogen atom. or a substituent group, R2 is a substituent group, (n) is a number of group R2, W is a substd. phenyl group, A is acylamino or anilino group, Z is a coupler releasing group. |
