COLORING MATTER FOR HEAT-SENSITIVE TRANSFER AND HEAT-SENSITIVE TRANSFER SHEET USING THE COLORING MATTER

摘要

PROBLEM TO BE SOLVED: To improve the solubility in a solvent for preparing an ink, the keeping stability of a coloring matter in the ink, the keeping stability of the coloring matter in a coloring material layer on a heat-sensitive transfer sheet and the keeping stability of the coloring matter in a image receiving layer on an image receiving sheet by adding a coloring matter for heat-sensitive transfer expressed by formula to the coloring material layer. ;SOLUTION: A coloring matter for heat-sensitive transfer expressed by formula [in the formula, A is a cycloalkyl group; R¹, R² are an alkyl group, an alkoxy group or a halogen atom; R³, R⁴ are the alkyl group, the halogen atom or -NRCOR⁷(R⁷ is a hydrogen atom or the alkyl group and an aryl group); R⁵, R⁶ are the alkyl group, an allyl group and the aryl group] is solved in a solvent or is dispersed in a microparticulate form into the solvent, together with a binder resin, to adjust an ink. This ink is applied to the surface of a support and then is dried to_-form a coloring material layer on the support. Thus it is possible to realize a highly concentrated heat-sensitive transfer recording and at the same time, obtain a sharp heat-sensitive transfer image.;COPYRIGHT: (C)1998,JPO
