Abstract
A heat-developable color photographic material is disclosed. The material is comprised of a support having thereon at least a light-sensitive silver halide, a hydrophilic binder, a dye releasing compound reductive and capable of releasing a hydrophilic dye and a compound represented by the following general formula (A): ##STR1## wherein A.sub.1, A.sub.2, A.sub.3, and A.sub.4, which may be the same or different, each represents a hydrogen atom or a substituent selected from an alkyl group, a substituted alkyl group, a cycloalkyl group, an aralkyl group, an aryl group, a substituted aryl group and a heterocyclic group, or A.sub.1 and A.sub.2 or A.sub.3 and A.sub.4 may combine with each other to form a ring. The heat-developable color photographic material can easily provide in a short time a clear and stable color image having a high color density and low fog by imagewise exposure and heat development procedure. A method of forming a color image using the heat-developable color photographic material is also disclosed.
