Heat-developable light-sensitive material

Abstract

A heat-developable light-sensitive material is described, comprising a support having provided thereon at least (a) a binder; (b) a light-sensitive silver halide; (c) at least one silver salt of a compound represented by formula (I) or (II) ##STR1## wherein Z represents a non-metallic atomic group forming a heterocyclic ring together with the nitrogen atom, A--C.tbd.C--H (II) wherein A represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; (d) a silver salt of a compound represented by formula (III) B--S--H (III) wherein B represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; and (e) a reducing agent. The material exhibits stable developability despite variations in development temperature or time, and provides an image having high maximum density and low minimum density.
