Abstract
This invention provides a heat-sensitive recording material comprising a substrate and a heat-sensitive recording layer which is formed over the substrate and which contains a diazonium salt, a coupler and at least one of specific heat-fusible basic amidine and diamidine compounds in which the nitrogen atom(s) of ##STR1## moiety(moieties) has(have) a substituent and the nitrogen atom(s) or ##STR2## moiety(moieties) has(have) at least one substituent, the substituent being independently selected from the group consisting of phenyl, naphthyl, phenyl-C.sub.1 -C.sub.4 alkyl and naphthyl-C.sub.1 -C.sub.4 alkyl, each optionally substituted with C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, phenyloxy, nitro or halogen, and in which amidine compounds are other than formamidines. The heat-sensitive recording material is especially excellent in storage stability.
