PURPOSE:To enable transfer recording having sufficient density by low energy, and to conduct yellow system recording having excellent can stability by containing quinophthalon dyestuffs and pyridone azo dyestuffs shown in specific chemical formulae in the coloring material layer of a thermal transfer sheet. CONSTITUTION:In the thermal transfer sheet used for sublimation type thermal transfer recording, a binding agent and a coloring material layer containing dyestuffs shown in general formulae I, II mentioned on the right are formed onto a base film. In formulae, X represents a hydrogen atom or a halogen atom, and Y the hydrogen atom and COOR<1> or CONR<2>R<3>. R<1>-R<3> represent the hydrogen atom, a substituted or non-substituted alkyl group, an aryl group, etc., R<4> the hydrogen atom, the substituted or non-substituted alkyl group, the aryl group, a cycloalkyl group, etc., Z the hydrogen atom or a methyl group, and A a benzing ring, which may have a nonionic substituting group. Each dyestuff is kneaded with a resin as the binding agent and an organic solvent, etc., thus acquiring an ink composition for the thermal transfer sheet. |
