PURPOSE:To lessen the generation of the color stain or the color fog of the title material, and to improve the aging stability of the photosensitive material by incorporating a specified polymer type color stain inhibitor in the photosensitive material. CONSTITUTION:The color stain inhibitor composed of a (co)polymer contg. one or more kinds of recurring units shown by formulas I, II and III is incorporated in the photosensitive material. In the formula, R<1> is hydrogen or halogen atom etc., R<2> is hydrogen atom or alkyl group, etc., L is a divalent binding group, A is -CO- or -SO2- group, etc., X is -OH or -N(-R<6>)(-R<7>) group, R<6> and R<7> are each hydrogen atom or alkyl group, etc., (n) and (m) are each 0 or 1, R<3> and R<4> are each alkylene or arylene group, etc. And, the (co)polymer contains preferably hydrazine or hydroxyamino group as an endo group thereof, and preferably a group capable of directly binding with a binder or binding with the binder through a hardening agent. And, the (co)polymer contg. the recurring units shown by formula IV etc. is used for the (co)polymer. |
