(57) [Problem] To provide a developer composition and a heat-sensitive recording material which are excellent in color-forming sensitivity and storage stability of a color-formed image. SOLUTION: The developer composition and heat sensitivity containing at least one compound selected from the compounds represented by the general formula (1) and at least one compound selected from the compounds represented by the general formula (2) Recording material. Embedded image Embedded image (Wherein, R1 to R5, R8 to R12 represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, or an aryl group; R6 represents a hydrogen atom or an alkyl group; 7, R13 represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, or a hydroxyl group; 2, adjacent groups selected from R2 and R3, R8 and R9, or R9 and R10 may be bonded to each other to form a carbocyclic aromatic ring together with the substituted carbon atom. ) |
