| 摘要 | PURPOSE:To provide a thermal recording material having excellent solvent resistance and water resistance, by providing a protective layer comprising a carboxyl-modified polyacrylamide resin and a polyamide-epoxy resin as main constituents on a thermal color forming layer. CONSTITUTION:A thermal color forming layer comprising a colorless or light- colored leuco dye, an electron-acceptive substance for developing the color of the leuco dye when being heated and a binder as main constituents is provided on a base, and a protective layer comprising as a main constituent a composition comprising 70-98wt% of a carboxyl-modified polyacrylamide and 2-30wt% of a polyamide-epoxy resin is provided on the color forming layer. With such construction, a thermal recording material can be obtained which has excellent solvent resistance and water resistance, is free of lowering of color forming sensitivity, sticking or the like and has excellent head matching properties. | ||||||
