Abstract (en)
[origin: EP0441208A1] Use of azo dyes I <IMAGE> for thermal transfer printing, having the following meaning of the substituents: R<1> = H; C1-C15-alkyl, which can carry phenyl or phenoxy as substituents; cyclohexyl which can carry C1-C5-alkyl, C1-C5-alkoxy or halogen as substituents; phenyl which can carry C1-C5-alkyl, C1-C5-alkoxy, sulphonamido or halogen as substituents; thienyl which can carry C1-C5-alkyl or halogen as substituents, furanyl or pyridyl; a radical II [-W-O]n-R<4> II where W = identical or different C2-C6-alkylene; n = 1 to 6; R<4> = C1-C4-alkyl or phenyl or benzyl which can both carry C1-C4-alkyl or C1-C4-alkoxy as substituents; R<2> and R<3> = H; alkyl, alkoxy, alkoxyalkyl, alkanoyloxyalkyl, alkoxycarbonyloxyalkyl, alkoxycarbonylalkyl, haloalkyl, hydroxyalkyl or cyanoalkyl each having up to 15 C atoms, which can carry phenyl, C1-C4-alkylphenyl, C1-C4-alkoxyphenyl, halophenyl, benzyloxy, C1-C4-alkylbenzyloxy, C1-C4-alkoxybenzyloxy, halobenzyloxy, halogen, hydroxyl or cyano as substituents; cyclohexyl which can carry C1-C15-alkoxy or halogen as substituents, phenyl which can carry C1-C15-alkyl, C1-C15-alkoxy, benzyloxy or halogen as substituents; a radical II; D = a radical of a diazo component III D-NH2 III.
