PURPOSE:To obtain the title material having an excellent cyan color image and durability by incorporating a specified high b.p. org. solvent in the photosensitive material. CONSTITUTION:At least one kind of a compd. shown by formula I and at least one kind of a cyan color forming coupler shown by formula II are dispersed in at least one kind of the high b.p. org. solvent having a dielectric constant of <=6.0. The obtd. dispersion is incorporated in the photosensitive material. In formula I, R is -(Y)n-R' group, Y is -O- or -S- group, etc., (n) is 0 or 1, R' is a residual group of phosphoric acid, Q is a divalent group. In formula II, R1 is 2 to 4C straight chain or a branched alkyl group, X is hydrogen atom or an atom or a group capable of being released by a coupling reaction, R2 is a ballast group. Thus, the steady color image of the photosensitive material against light, heat and a wet heat is obtd. |
