| 摘要 |
An object of the present invention is to provide a thermal transfer recording sheet that enables images having a wide color gamut, a high chroma, and good lightfastness, in which the degree of catalytic fading is reduced, to be formed. The thermal transfer recording sheet includes a base material and a colorant layer on the base material. The colorant layer includes a yellow dye layer, a magenta dye layer, and a cyan dye layer. The dye layers each include, as a dye, a compound having a specific structure. |

1. A thermal transfer recording sheet comprising a base material and a colorant layer on the base material,
wherein:the colorant layer includes
a yellow dye layer comprising a yellow dye, a magenta dye layer comprising a magenta dye, and a cyan dye layer comprising a cyan dye, the magenta dye containing a compound represented by General Formula (1), the yellow dye containing at least one compound selected from the group consisting of compounds represented by General Formulae (2) to (5), and the cyan dye containing at least one compound selected from the group consisting of compounds represented by General Formulae (6) to (8), wherein, in General Formula (1), R1 to R6 each independently represent an alkyl group, and R3 to R5 may be bonded to one another to form a ring; and R7 and R8 each independently represent an alkyl group or an acyl group or are bonded to each other to form a ring, wherein, in General Formula (2), R9 to R12 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent, wherein, in General Formula (3), R13 and R14 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent; and R15 and R16 each independently represent a hydrogen atom, an alkyl group, an aryl group having no substituents, an aryl group having a substituent, an alkoxy group, a cyano group, or a halogen atom, wherein, in General Formula (4), R17 and R18 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent, wherein, in General Formula (5), R19 and R20 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent, wherein, in General Formula (6), R21 to R25 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent, wherein, in General Formula (7), R26 and R27 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent, and wherein, in General Formula (8), R28 to R32 each independently represent an alkyl group, an aryl group having no substituents, or an aryl group having a substituent. |
