PURPOSE:To prevent generation of foggings by incorporating at least one selected from specific compds. into at least one silver halide emulsion layer and the hydrophilic colloidal layer adjacent thereto. CONSTITUTION:At least one selected from the compds. expressed by the formulas I and II is incorporated into at least one silver halide emulsion layer and the hydrophilic colloidal layer adjacent thereto. In the formulas, R<1>-R<3> respectively denote an alkyl group, aryl group or aralkyl group. The alkyl group is preferably an alkyl group of 1-20C, and may be either straight chain or branch. The aryl group is preferably a phenyl group, naphthyl group and may be substd. The aralkyl group is exemplified by groups such as benzyl and phenethyl and these phenyl groups may have a substituent. The generation of the foggings is thereby prevented. |
