ABSTRACT:
A heat-developable light-sensitive material comprising a support having thereon at least one layer containing (a) an organic silver salt oxidizing agent; (b) a catalytic amount of a light-sensitive silver halide or a compound capable of forming a light-sensitive silver halide through reaction with the organic silver salt component (a); (c) a reducing agent; and (d) at least one compound represented by the following general formulae (I) to (III) ##STR1## in which A and B each represents different substituents selected from the group consisting of an amino group and a --OX group; X represents a hydrogen atom, an alkali metal atom, a silver atom, a mercury atom or a gold atom; R.sub.1 and R.sub.2 each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an aralkyl group, an allyl group, an acyl group, an aryl group or an aryloxy group; and R.sub.3, R.sub.4 and R.sub.5 each represents a hydrogen atom, a halogen atom or an alkyl group.
