Abstract
Abstract A silver halide photographic material having a hydrophilic colloid layer comprising fine polymer particles loaded with a hydrophobic photographic addenda provided on a support wherein the polymer has repeating units formed from a nonionic hydrophobic monomer. The nonionic hydrophobic monomer has the formula <IMAGE> +TR <IMAGE> R1 and R2 individually are a hydrogen atom or methyl group, R3 is a hydrogen atom, an alkyl or aryl group, and m and n are integers of from 2 to 100 individually.
