METHINE AND AZAMETHINE DYES COMPRISING TRIFLUOROMETHYL GROUP-CONTAINING 5-MEMBERED HETEROCYCLE AS BASE, PROCESS FOR DYE TRANSFER FROM SUBSTRATE TO POLYMER-COATED PAPER AND DYEING AND PRINTING OF SYNTHETIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a dye useful for dye thermal transfer, dyeing and printing by selecting a specific (aza)methine dye with a 5-membered heterocycle having CF3 group as a central forming block and without a water-soluble group. SOLUTION: A dye represented by the formula: Q1 -X=Het [wherein X is N or CH; Q1 is one selected from groups represented by formulas I to V or the like; Het is a divalent group represented by formula VI or VII; n is 0 or 1; Z1 is H, a 1-13C alkyl, 1-4C alkoxy, OH or the like; Z2 is the same as Z5 or a 1-4C alkoxy; Z3 and Z4 are each H, a 1-13C alkyl, 3-4C alkenyl or the like; Z5 is H or a 1-4C alkyl; Z6 is H, a halogen, 1-13C alkyl or the like; Z7 is H, a 1-13C alkyl, phenyl or the like; Y is O, S, (1-4C alkyl)imino, phenylimino or a group of an acidic CH compound; A is N or a group represented by the formula: C-U; U is H, a 1-13C alkyl, halogen, CN or 1-13C alkoxycarbonyl; E is O, S, Se, a (1-4C alkyl)imino or phenylimino] is selected. For example, a dye represented by formula VIII is cited.
