PURPOSE:To obtain a colorant for yellow heat transfer having excellent various rigidity, color value, sufficient heat resistance stability and transferring speed at the time of transfer by composing the title colorant of a specific colorant. CONSTITUTION:A colorant represented by a formula (where R<1> is lower alkyl group, R<2> is alkenyl group, alkoxyalkyl group, aralkyl group, cycloalkyl group, alkenyl group or lower alkoxycarbonylmethyl group) is provided. The concrete example of the R<1> includes lower alkyl group of methyl group, ethyl group. The R<2> includes alkyl group of methyl group, ethyl group, alkoxyalkyl group of methoxymethyl group, methoxyethyl group, etc. aralkyl group of benzyl group, phenethyl group, etc., cycloalkyl group of cyclopropyl group, cyclobutyl group, etc., alkenyl group of aryl group, 1-butenyl group, etc. Further, it includes lower alkoxycarbonylmethyl group of methoxycarbonylmethyl group, ethoxycarbonylmethyl group, etc. |
