The heat sensitive transcription ink sheet, the ink cartridge, in the application constituent for dye formation of the heat sensitive transcription ink sheet and on the heat sensitive transcription

摘要

PROBLEM TO BE SOLVED: To provide a coating composition for the dye layer of a heat-sensitive transfer ink sheet which is highly sensitive and free from image defects, and a heat-sensitive transfer recording method.;SOLUTION: The heat-sensitive transfer ink sheet has the dye layer formed on a support by containing a heat transfer dye in a resin binder. The dye layer contains a polyvinyl acetal modified by a chemical compound represented by at least a kind of formula [1]. In the formula [1], either of R¹ or R² is a branched hydrocarbon group, and the other is a hydrogen atom or a hydrocarbon group. Alternatively, R¹ and R² are bonded with each other to express a group for forming a cyclic hydrocarbon.;COPYRIGHT: (C)2009,JPO&INPIT
