Image-forming process involving heating step
 An image-forming process involving a heating step is disclosed, which comprises conducting the heating in the presence of a compound represented by the following general formula (I): ##STR1## wherein: R.sup.1 and R.sup.2, which may be the same or different, each represents a group selected from an aryl group, a substituted aryl group, a heterocyclic group, and a substituted heterocyclic group; PA1 R.sup.3 represents a hydrogen atom, an alkyl group, a substituted alkyl group, a cycloalkyl group, a substituted cycloalkyl group, an aralkyl group, a substituted aralkyl group, or a group selected from those which are referred to with respect to R.sup.1 and R.sup.2 ; PA1 R.sup.1, R.sup.2, and R.sup.3 may form a ring structure via a hydrocarbon chain, a hetero atom-containing hydrocarbon chain or a hetero atom, or may be directly bound to each other to form a ring structure; and PA1 PUG represents a photographically useful group.
