Photographic light-sensitive material containing antistatic acid polymer

Claim 1

A photographic light-sensitive material, comprising: a support base; a silver halide emulsion layer; and an antistatic emulsion layer comprising a gelatin having dispersed therein a polymer having repeating units represented by the following general formula (I): ##STR62## wherein A represents a repeating unit derived from a copolymerizable ethylenic unsaturated monomer which contains at least one free carboxyl group or a salt thereof; R 1 represents a hydrogen atom or a lower alkyl group having 1 to 6 carbon atoms; Q represents --CO 2 --, ##STR63## or an arylene group having 6 to 10 carbon atoms; L represents a divalent group having 3 to 15 carbon atoms and containing at least one linkage selected from the group consisting of --CO 2 -- and ##STR64## or a divalent group having 1 to 12 carbon atoms and containing at least one linkage selected from the group consisting of --O--, ##STR65## --CO--, --SO--, --SO 2 --, --SO 3 --, ##STR66## (wherein R 1 has the same meaning as described above); R 2 represents --CH═CH 2 or --CH 2 CH 2 X (wherein X represents a group capable of being substituted with a nucleophilic group or a group capable of being released in a form of HX upon a base); and x and y represent percentages by mole fraction ranging from 50 to 99, and 1 to 50, respectively.
