PURPOSE:To enable a change of the color tone of a silver image without lowering the sensitivity by incorporating a specified compd. into at least one of constituent layers. CONSTITUTION:At least one kind of compd. represented by formula I is incorporated into at least one of constituent layers. In formula I, X<1> is a bivalent combining group bonding to C through a hetero atom., A is a group bonding to X<1> through the hetero atom. of A and regulating the color tone of a silver image, each of R<1>-R<3> is H or a substitutable group, R<1> and R<2>, and R<1> and R<3> may bond to each other to form a carbon ring or a hetero ring, Y is cyano or nitro, n=0 or 1, m=0 or 1, and in case of m=0, A bonds to C through the hetero atom. of A. Thus, a sensitive material having a fine color tone is obtd. |
