PURPOSE: To approach to a hue of a yellow SWO color reference by using a specific yellow dye mixture as a yellow dye donor element for thermal dye transfer. CONSTITUTION: The yellow dye donor element for thermal dye transfer comprises one or more of yellow dye represented by a formula I [R<1> is, for example, an alkyl, cycloalkyl or the like, n is an integer of 0 to 4, R<2> and Y are each a hydrogen or, for example, an alkyl, cycloalkyl or the like, Z is, for example, a cyano or the like] and one or more of yellow dye represented by a formula II [R<3> , R<6> and G are each, for example, an alkyl, cycloalkyl or the like, R<4> and R<5> are each a hydrogen or, for example, an alkyl, cyano or the like, X is, for example, S, T are each a condensed ring]. |
