PURPOSE: To obtain a thermal recording material excellent in raw preservability and having rapid heat response and fixable by light after thermal recording by containing an acylamide derivative in a recording layer. n CONSTITUTION: A recording layer containing a diazo compound and a coupling component is provided on a support and contains an acylamide derivative. Either one of said diazo compound and the coupling component is pref. contained in a microcapsule. As the pref. acylamide derivative, for example, there is a compound represented by formula (I) (wherein R 1 is an alkyl group or aryl group which may have a substituent, R 2 is an alkyl group which may have a substituent such as a cyano group, a carbonato group, a carboxyl group, a carbamoyl group or an alkoxycarbonyl group). n COPYRIGHT: (C)1990,JPO&Japio |
