(57) [Summary] [Objective] A dye for thermal transfer recording having a high sublimation rate and image stability after transfer is obtained. [Structure] The following general formula (I): [In the formula, R 1 represents a hydrogen atom, an alkyl group, an aryl group, An alkylcarbonyl group, an arylcarbonyl group, a heterocyclic group, or a heterocycle-substituted carbonyl group, R 2 represents a hydrogen atom, a halogen atom, or an alkyl group, and R 3 and R 4 are the same or independently of each other, a hydrogen atom, An alkyl group, an aryl group, an alkylcarbonyl group, an arylcarbonyl group or a ring formed by linking with each other, R 5 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkylcarbonyl group, or an aralkyl group, R 6 represents a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, R 7 and R 8 are the same or independent, and each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, an aryl group, an alkenyl group, an aralkyl group, or a ring formed by connecting to each other. Used as a dye for thermal transfer recording. |
