THERMAL RECORDING MATERIAL

PURPOSE: To improve sticking by providing an ultraviolet curable resin layer of which the surface is specified in the coefficient of dynamic friction on a protective layer. CONSTITUTION: The coefficient of dynamic friction of the surface of an ultraviolet curable resin layer is set to 0.2 or less and an additive enhancing surface lubricity such as a metal salt of fatty acid, an org. filler, a silicone resin, fluoroplastic or wax is added to the ultraviolet curable resin layer. By adding a metal salt of fatty acid with an m.p. of 80-150 deg.C to the ultraviolet curable resin layer, the metal salt of fatty acid is melted when printing is performed by a thermal head and the friction force between the thermal head and the surface of a thermal recording material is markedly reduced. The sticking force of the ultraviolet curable resin layer to the thermal head is markedly lowered by the release effect of the metal salt of fatty acid and, therefore, sticking properties can be improved.
