PURPOSE:To improve the film characteristics of the title material such as the dimensional stability and the scratching strength, etc., without interacting adversely to photographic characteristics by incorporating a specified polymer in a sensitive material. CONSTITUTION:The polymer having a repeating unit shown by formula I is incorporated in one or more layers of the constituting layers contd. in the sensitive material. In the formula, R is hydrogen or halogen atom, etc., R1 and R2 are each hydrogen atom or 1-10C alkyl group, etc., at least one of the groups R1 and R2 is a group having a sulfide binding. The repeating unit shown by the formula is composed of a monomer shown by formula II, etc., and the polymer may be composed of a copolymer of the monomer shown by formula II and an another ethylenically monomer. By incorporating the polymer in a hydrophilic colloid layer, the flocculation and the precipitation of the polymer do not occur, and the devitrification phenomenon of the polymer does not generate, and the film characteristics of the sensitive material can be improved, without affecting adversely the photographic characteristic of the sensitive material. |
