PURPOSE:To lessen the residual color stain of the photosensitive material after processing by mounting a hydrophilic colloid layer contg. a specified dyestuff on the sensitive material. CONSTITUTION:The hydrophilic colloid layer contg. the dyestuff shown by formula I is mounted on the sensitive material. In the formula, R1-R6 are each alkyl group, Z1 and Z2 are each a nonmetal atomic group necessary for forming a benzocondensed ring or a naphthocondensed ring, R7 is hydrogen atom or alkyl group, L is a methine group, X<-> is an anion, (m) is an integer of 1-5, (n) is an integer of 1 or 2, when the dyestuff forms an inner complex salt, (n) is 1. Thus, the residual color of the sensitive material after developing, is lessened. |
