摘要:
A thermo-developable type diazo copying material including a substrate and a heat sensitive recording layer, superposed on said substrate, which consists essentially of a diazo compound, a coupler and a heat-fusible color assistant, characterized in that said heat sensitive recording layer is of the multilayered type comprising a diazo compound-containing layer and a coupler-containing layer, and said coupler is composed of one or two or more of the compounds having the following general formula: ##STR1## wherein X is hydrogen, halogen, an alkyl group having 1-4 carbon atoms or an alkoxyl group having 1-4 carbon atoms; R.sup.1 is an alkyl group having 10-25 carbon atoms; and R.sup.2 is hydrogen or an alkyl group having 1-30 carbon atoms.
