摘要：
A dyestuff for heat-sensitive transfer record is here disclosed which can be represented by the formula (1)
wherein R₁ is a hydrogen atom, alkyl group having 1 to 8 carbon atoms or cycloalkyl group; R₂ is a hydrogen atom, halogen atom, alkoxy group which may be substituted, alkylthio group which may be substituted or arylthio group which may be substituted; R₃ is a branched alkyl group having 3 to 5 carbon atoms, O-substituted oxycarbonyl group, N-substituted aminocarbonyl group in which an N-substituted group may form a ring, or a substituted or unsubstituted heterocyclic ring having two or more atoms of one or more kinds selected from the group consisting of a nitrogen atom, oxygen atom and sulfur atom; and when R₁ is a hydrogen atom, R₃ is a branched alkyl group having 3 to 5 carbon atoms, or a substituted or unsubstituted heterocyclic ring having two or more atoms of one or more kinds selected from the group consisting of a nitrogen atom, oxygen atom and sulfur atom; and there are also disclosed an ink for heat-sensitive transfer record and a transfer sheet in which the above-mentioned dyestuff is used.
