PURPOSE:To stably form the high contrast image of the title material, even in case of using the photosensitive material contg. a hydrazine compd. by incorporating a hydrazine derivative in a photosensitive silver halide emulsion layer, and by curing a hydrophilic colloid layer with a N,N'-disuccinimido oxalate compd. or its derivative. CONSTITUTION:In the photosensitive material applied the hydrophilic colloidal layer contg. the photosensitive silver halide emulsion layer on a supporting body, the hydrazine derivative is incorporated in the photosensitive silver halide emulsion layer, and the hydrophilic colloid layer is cured by the N,N'- disuccinimidooxalate compd. or its derivative. The hydrazine derivative is exemplified by a compd. shown by formula I, II or III. In the formulas, R1 and R2 are each aryl group, etc., R is an org. binding group, (n) is 0-6, (m) is 0 or 1, R21 is an aliphatic group, etc., R22 is hydrogen atom, etc., P1 and P2 are each hydrogen atom, etc., Ar is an anti-diffusion group or an aryl group contg. a silver halide absorbing group, etc. R31 is a substd. alkyl group. Thus, the high contrast image of the photosensitive material is stably formed. |
