ABSTRACT:
A heat-developable color photographic material comprising a support having thereon at least a light-sensitive silver halide, a hydrophilic binder, a dye releasing redox compound and a heat fusible compound which has a melting point of 60.degree. C. or higher and is represented by the following general formula (I), (II) or (III): ##STR1## wherein m represents an integer from 1 to 3; n represents an integer from 1 to 8; q represents an integer from 1 to 4; p represents an integer which meets the requirement for p+g=6; s represents an integer from 1 to 4; r represents an integer which meets the requirement for r+s=8; R represents a hydrogen atom or a substituent as set forth in the specification, and when m, p or r represents 2 or more, R may be the same or different; R.sub.1 represents an organic group in R.sub.1 - (OH).sub.n which is an alcohol, a phenol or a naphthol each having one or more hydroxy group and includes a saccharide; and R.sub.2 represents an organic group in R.sub.2 - OH which is an alcohol, a phenol or a naphthol.
The heat-developable color photographic material has improved stability during storage before imagewise exposure and the occurrence of fog and the change in the maximum density therein are minimized.
