PURPOSE:To form images which are heightened in the max. density and are lowered in the min. density and are free from unequal densities by subjecting a photosensitive material which is specific in dry film thickness and saturated swelling film thickness to a heat development at a prescribed temp. CONSTITUTION:The heat developable color photosensitive material is the photosensitive material made into the multilayered constitution contg. photosensitive silver halides, reducing agents, and reducible color donative compds. (A), etc. Total dry film thickness of photosensitive layer side is <=10mu and saturated swelling film thickness by water is <=20mu. After water is imparted to this photosensitive material, the material is superposed on a dye fixing material and is then subjected to the heat development at 65 to 85 deg.C, by which the positive image is formed. The compds. expressed by the formula, etc., are usable as the compds. A. In the formula, PWR denotes a group which releases (Time)t-Dye by reduction; Time denotes a group which releases Dye after released from PWR; t denotes 0, 1; Dye denotes a dye (precursor). |
