Abstract:
A process for printing fibrous textile materials according to the ink-jet printing technique, which process comprises printing the fibrous materials with an aqueous ink comprisinga) a pigment dye of formula whereinR52 is hydrogen, halogen, C1-C4alkyl, C1-C4alkoxy, nitro or cyano, R53 is hydrogen, halogen, nitro or cyano, R54 is hydrogen, halogen or phenylaminocarbonyl, R55 is hydrogen or hydroxy, and R56 is hydrogen or a radical of formula whereinR57 is hydrogen, C1-C4alkyl or C1-C4alkoxy, R58 is hydrogen, C1-C4alkoxy or halogen, and R59 is hydrogen, C1-C4alkyl, C1-C4alkoxy or halogen, whereinR60 and R61 are each independently of the other C1-C4alkyl and R62 and R63 are halogen, wherein the rings A, B, D and E are unsubstituted or mono- or poly-substituted by halogen, whereinR64 is C1-C4alkyl, R65 is hydrogen, halogen, C1-C4alkyl, C1-C4alkoxy, nitro or cyano, R66 is hydrogen, halogen, nitro or cyano, R67 is hydrogen, halogen, C1-C4alkyl, C1-C4alkoxy, nitro or cyano, wherein the rings Aâ€² and Bâ€² are unsubstituted or mono- or poly-substituted by halogen, wherein in(R68)0-2and (R68â€²)0-2 each independently of the other denote from 0 to 2 substituents selected from the group halogen, C1-C4alkyl, C1-C4alkoxy, nitro and cyano, and K1 and K2 are each independently of the other a radical of formula wherein(R69)0-3 and (R69â€²)0-3 each independently of the other denote from 0 to 3 substituents select group halogen, C1-C4alkyl, C1-C4alkoxy, nitro and cyano, especially halogen, C1-C4alkyl and C1-C4alkoxy, or inorganic pigment dyes based on carbon black or iron oxides, b) a water-dispersible or water-soluble mixture of pigment dye binders wherein one component of the mixture is based on the polymerisation product of acrylic acid and another component of the mixture is based on the polymerisation product of acrylic acid and urethane, and c) glycerol, propylene glycol or diethylene glycol.
