Zusammenfassung:PURPOSE:To enhance the safety of a sensitive material to safelight and the sharpness of a color image and to reduce residual color after processing by using a specified spectral sensitizer and a specified dye. CONSTITUTION:One or more of the silver halide emulsion layers of a sensitive material are spectrally sensitized with a compd. represented by formula I and one or more kinds of dyes represented by formula II are incorporated into one of the nonphotosensitive or photosensitive layers. In the formula I, Z1 is O or S, each of R1 and R2 is (substd.) alkyl, each of V1-V8 is H, halogen, etc., X is a counter ion and n is a prescribed value. In the formula II, each of X' and X'' is H, hydroxyl, etc., each of Y and Y' is H, alkyl, etc., each of Z2 and Z2' is H, cyano, etc., each of L1-L5 is methine, each of n1 and n2 is 0 or 1 and M is a cation. A compd. represented by formula III is preferably incorporated into the emulsion layers are hypersensitizer. In the formula III, D is an arom. residue, each of R7-R10 is H, hydroxyl, etc., and each of Y1, Y2, Y3 and Z4 is -N=, etc.
