Abstract (en)
[origin: EP0462447A1] Use of azo dyes I <IMAGE> for thermal transfer printing, in which the substituents have the following meaning: R<1> is H, amino, hydroxyl or C1-C3-alkyl; R<2> is H, acetyl, carbamoyl or cyano; R<3> is omega -phenoxy-, omega -tolyloxy-, omega -benzyloxy- or omega -cyclohexyloxy-C1-C12-alkyl, whose C chain can be interrupted by one or two of the following non-adjacent members -O-, -CO-, -O-CO- or -CO-O- and which can carry one or two of the following substituents: halogen, hydroxyl, C1-C2-alkyl, phenyl or cyclohexyl; R<4>, R<5> are H, halogen, cyano, nitro or trihalomethyl; radicals -CO-H, -CO-R<6>, -O-CO-R<6>, -CO-OR<6>, -SO-OR<6>, -O-SO-OR<6>, -CO-NR<7>R<8>, -O-CO-NR<7>R<8>, -SO2-NR<7>R<8> or -O-SO2-NR<7>R<8> in which R<6> is C1-C12-alkyl, omega -phenoxy-, omega -tolyloxy-, omega -benzyloxy- or omega -cyclohexyloxy-C1-C12-alkyl, whose C chain can in each case be interrupted by one or two oxygen atoms in an ether function; R<7> is C1-C12-alkyl; R<8> is H or one of the radicals R<7>.
