| 摘要 |
The present invention relates to aqueous inks comprising (A) at least one dye of the formula (1) wherein R1 is C1-C12alkyl, or C2-C12alkyl interrupted by one or more oxygen atoms and/or —COO— groups, and R2, R3, R4 and R5 each independently of the others is hydrogen, C1-C12alkyl, chlorine, bromine, hydroxy or amino; (B) at least one dye of the formula (2) wherein R6 is hydrogen, bromine, chlorine or cyano, R7 is trifluoromethyl, bromine or chlorine, R8 is hydrogen, methyl or acetylamino, R9 and R10 each independently of the other is C1-C4alkyl unsubstituted or substituted by cyano or by acyloxy, one of the C1-C4alkyl radicals R9 and R10 is substituted by cyano or by acyloxy; and (C) at least one dye of the formula (3) wherein R11 is fluoro, trifluoromethyl, trifluoromethoxy, trifluoromethylsulfonyl or cyano, R12 and R13 each independently of the other represent hydrogen, C1-C12alkyl, C1-C12alkoxy, halogen, cyano, nitro, trifluoromethyl or —CO—OR16, wherein R16 is C1-C12alkyl unsubstituted or substituted by one or more C1-C12alkoxy, hydroxy, amino or halogen, and one of the radicals R14 and R15 denotes hydrogen or CrC6alkyl unsubstituted or substituted by hydroxy, C1-C4acyloxy, C1-C6alkoxy, C1-C4acyloxy-C1-C6alkoxy or hydroxy-C1-C6alkoxy, and the other one of the radicals R14 and R15 denotes C1-C6alkyl unsubstituted or substituted by phenoxy-C1-C6alkoxy, or phenyl that is unsubstituted or substituted by one or more substituents from the group C1-C12alkyl, C1-C12alkoxy and trifluoromethyl; and to an ink-jet printing process for printing semi-synthetic or synthetic hydrophobic textile fiber materials with the said aqueous inks, wherein the prints obtained have high temperature light fastness and at the same time a high color strength. |
