HEAT-SENSITIVE CHROMOGENIC COMPOSITION AND HEAT-SENSITIVE RECORDING MATERIAL FORMED USING SAID COMPOSITION

摘要

[Problem] To provide a heat-sensitive recording material having high fastness and a clear hue. [Solution] A heat-sensitive chromogenic composition comprises: a hydroxyquinoline compound having a methyl group; and an acid anhydride compound represented by general formula (1). The heat-sensitive recording material is formed containing the composition in a recording layer. [In the formula, ring A represents a substituted or unsubstituted aromatic hydrocarbon ring, and n represents an integer from 1 to 3.]
