PURPOSE:To obtain a sharp dye image by forming a dye to an image shape after or simultaneously with imagewise exposure in the presence of a specific compd. thereby supressing the generation of fogging and the change of the max. density during the preservation prior to development. CONSTITUTION:A color photosensitive material is heated after or simultaneously with the imagewise exposure in the presence of >=1 kinds of compds. selected from the compds. expressed by the formulas I-V to form the dye to the image shape. In these formulas, RA is an aliphat. (AL) hydrocarbon (HC) group of m+n valency, R<1> is AL, alicyclic or arom. (AR) HC group, m, n are 1-5; RB is AL or alicyclic HC group of p+q valency, R<2>.R<3> are reepctively AL or alicyclic HC group, p, q are respectively 0-3, p+q>1; RC is H, AL, alicyclic or AR HC group, acyl, amino, etc., R<4> is synonymous with R<1>, r is 1-4, S is 1-5, r+s<6, R<5>, R<6> are alkyl, mono- or poly-alicyclic HC group, aryl group, etc., R<7> is an alkyl, aryl, etc., Z is a carbon ring forming atomic group to be condensed to a benzene ring, l is 0, 1, v is 0-2, w is 0-7, v+w<7, R<8> is aralkyl, cycloalkyl, etc. |
