PROBLEM TO BE SOLVED: To manufacture a heat-sensitive recording material having extremely superior light fastness for effectively controlling texture light exposure coloring. SOLUTION: A heat-sensitive recording material is provided with at least one heat-sensitive recording layer on a substrate, and at least one layer of the heat sensitive recording layer contains a 0.05 g/m2 or more compound represented by a formula R-SO3M. (In the formula, R represents an alkyl, an aryl, an alkoxyl, an aryloxy, a polyoxyethylenearyl or a polyoxyalkyl, M represents an alkaline metal). |
