PURPOSE:To improve the light durability of the title material by incorporating at least one kind of a specified magenta coupler and at least one kind of a specified compd. in the photosensitive material. CONSTITUTION:At least one kind of the magenta coupler shown by formula I and at least one kind of the compd. shown by formula II are incorporated in the photosensitive material. In formula I, X0 is hydrogen atom or a substituting group, Z1 is hydrogen atom or a group capable of being released by coupling, W is hydrogen atom or acyl group, etc., Za and Zb are each methine or a substd. methine group or -N= group. In formula II, 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. Thus, the durability of an image against light, heat and humidity is improved, the generation of a stain is prevented, and especially, the excellent anti-discoloring effect of the photosensitive material against the light is obtd. |
