Abstract:
The purpose of the present invention is to provide a heat-sensitive recording medium for which concerns regarding safety, such as endocrine-disrupting substances, are low, which has excellent chromogenic properties and light resistance, and which has excellent heat resistance. A heat-sensitive recording body (1) has a configuration in which a heat-sensitive recording layer (3) is layered on a substrate (2). The heat-sensitive recording layer (3) contains a coloring agent, a non-phenolic developer, and a non-phenolic light stabilizer. The non-phenolic light stabilizer contains a hindered amine light stabilizer.
