Abstract
A thermosensitive recording material composed of a support, a thermosensitive recording layer formed on the support, capable of producing colored images by heating, and a protective layer formed on the thermosensitive recording layer, which contains as a resin component a copolymer resin obtained by copolymerization of arylamide or methacrylamide, acrylonitrile, and a vinyl monomer having a carboxyl group, or a copolymer resin of a core-shell emulsion type obtained by copolymerization of acrylamide and/or methacrylamide in the presence of a seed emulsion of an acryl-based copolymer or methacryl-based copolymer, and as a crosslinking agent a compound having two or more alkyleneimino groups, a carbodiimide compound, a methyl ethyl ketoxime compound, or bis(.beta.-hydroxyethyl)sulfone.
