ABSTRACT:
A heat-developable photographic light-sensitive material is described, comprising a support having thereon, at least one layer containing a compound represented by the general formula (I) or (II) below: ##STR1## wherein R and R' each represents a group selected from a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, an amino group, an acylamino group, an alkoxy group, an alkylthio group, a sulfonylamino group, a heterocyclic ring group and a substituted group of them; X represents atoms forming a 5-membered or 6-membered ring; A represents a group causing a decarboxylation reaction.
This heat-developable photographic light-sensitive material provides a high maximum density and low fog by heat-developing at a relatively low temperature and for a short time.
