PROBLEM TO BE SOLVED: To provide a thermal recording medium having excellent recording sensitivity, preservation stability of a skin and image and printability by providing a recording layer containing leuco compound, salicylic acid derivative, methylolamide, and oxalic di(p-methylbenzyl) on a support. SOLUTION: The thermal recording medium is obtained by laminating a recording layer containing leuco compound, at least one of salicylic acid derivative represented by the general formula I (in the formula, X1 , X2 are hydrogen atom, alkyl group, aralkyl group, aryl group, or halogen atom, R is alkyl group, alkenyl group, aralkyl group, or aryl group) or its metal salt, methylolamide, oxalic di(p-methylbenzyl) or oxalic di(-chlorobenzyl) on a support. The salicylic acid derivative represented by the general formula I includes, for example, 3-methoyoxycarbonylaminosalicylic acid, and 3-n-propyloxycarbonylaminosalicylic acid. |
