PURPOSE: To obtain coloring of a colorless gray scale and to upgrade a resin resistance by providing a coating film mixed with specific different amounts of four types of black dyes represented by specific general formulae on a support, and forming a thermal transfer print sheet. CONSTITUTION: The thermal transfer print sheet is formed by providing a coating film containing a mixture of 5 to 60% of a dye represented by formula I (wherein X is an H, a nitro group or the like Y is 1-20C alkyl group or the like, Z is an alkyl group, and R is an O, alkyl group), 5 to 60% of a dye represented by formula II (wherein A is a heteroaromatic amine, E is an aromatic coupling component), 5 to 60% of a dye represented by formula III (wherein C is a phenylamine or the like, G is an aromatic coupling component) and 5 to 60% of a dye represented by formula IV (wherein R is 1-6C alkyl group or the like) and a binder on a support. |
