PURPOSE: To obtain a sharp color image by a simple method using a specified substance for giving a dye as a hydrophilic dye releasable by heat development.
CONSTITUTION: A thermodevelopable color photosensitive material contains photosensitive silver halide, a hydrophilic binder, and a dye donor represented by general formula I in which Q
1 is H, halogen, alkoxy, acylamino, or sulfonylamino; Q
2 , Q
3 are each H, halogen, alkyl, alkoxy, or amino; G is OH or a group convertible into it by hydrolysis; Y is a group represented by general formulae IIWIX; R
11 WR
14 are each H, alkyl, cycloalkyl, aryl, alkoxy, aryloxy, aralkyl, acyl, acylamino, alkylsulfonyl, arylsulfonylamino, aryloxyalkyl, alkoxy- alkyl, N-substd. carbamoyl, or the like.
