Disperse dye mixtures, their preparation and use

Abstract

The present invention provides dye mixture containing at least one dye of formula (I) and at least one dye of formula (II) where T 1 is hydrogen, halogen, trifluoromethyl, cyano, SCN, -SO2CH3 or nitro; T 2 is hydrogen or halogen; R 1 is hydrogen, (C1-C6)-alkyl, (C1-C4)-alkoxy, halogen, -NHCHO, -NHCO(C1-C6)-alkyl, NHCOaryl, -NHSO2(C1-C6)-alkyl or NHSO2aryl; R 2 is hydrogen or halogen; R 3 is hydrogen, (C1-C6)-alkyl, cyano-, (C1-C4)alkoxy-, phenoxy- or phenyl- substituted (C1-C6)alkyl, (C3-C4)-alkenyl or substituted (C3-C4)alkenyl; R 4 is hydrogen or methyl; R 5 is methyl or ethyl; R 6 is hydrogen or methyl; R 7 is hydrogen or methyl; n is 0, 1, 2 or 3; R 8 and R9 are each independently hydrogen, (C1C4)-alkoxy, (C2-C4)-alkenyloxy or -O(CH2)qR 22; and q is an integer from 1 to 6; and R 22 is 2-tetrahydropyranyl, 2-tetrahydrofuranyl, OR23 or -COR24; where R 23 is hydrogen, (C1-C4)-alkyl, (C2-C4)-alkenyl, substituted or unsubstituted phenyl, (C1-C4)alkoxy-(C1-C4)-alkyl, phenoxy-(C1-C4)-alkyl, carbonyl-(C1-C4)-alkyl, carbonyl-(C2-C4)-alkenyl, carbonylphenyl, carbonyl-(C1-C4)-alkoxy-(C2C4)- alkyl or carbonylphenoxy-(C2-C4)-alkyl; and R 24 is (C1-C4)-alkoxy, (C2-C4)-alkenyloxy, substituted or unsubstituted phenyloxy, phenyl(C1-C2)-alkoxy, phenoxy-(C1-C4)-alkoxy, (C2C4)-alkenyloxy-(C1-C4)- alkoxy or (C1-C4)alkoxy-(C1-C4)-alkoxy.
