PURPOSE:To obtain the titled material capable of hardening a prescribed layer, without adversely affecting photographic characteristics, by hardening at least one layer of non-photosensitive layers between a silver halide emulsion layer and a substrate body with a specific high polymer hardener. CONSTITUTION:The titled material is formed by hardening at least one layer of the non-photosensitive layer between a silver halide emulsion layer and the substrate body with the high polymer hardener having the repeating unit shown by the formula wherein A is a monomer unit capable of co-polymerizing with an ethylenic unsatd. monomer. R1 is H, 1-6C alkyl group or halogen atom, etc., J is 1-6C alkylene, 6-10C arylene group or -O- binding; L is 3-15C bivalent binding group having one or more of -CO2- and -CONR3- bindings of 1-12C bivalent binding group having one or more of -O-, -NR-, -CO-, and -SO-, etc.; R3 is H or 1-6C alkyl or 6-12C aryl group; X is -CH=CH2, or -CH2CH2-Q group; Q is a group capable of releasing by a base or substituting by a nucleophilic group; X=0-99%, Y=1-100%, (n) is 0 or 1. |
