ABSTRACT:
Water-soluble fiber-reactive phthalocyanine compounds of the general formula (1) ##STR1## in which Pc denotes the radical of metal-free or metal-containing phthalocyanine, with the sulfonic acid or sulfonamide groups being bonded in the 3-positions of the aromatic rings of the phthalocyanine, R.sub.1 and R.sub.2 each denote a hydrogen atom or an alkyl group of 1-6 carbon atoms and which can be substituted by methoxy, ethoxy, propoxy, C.sub.2 H.sub.5 --O--C.sub.2 H.sub.4 --O--, cyano, acetylamino, carboxyl, HO.sub.3 S--, H.sub.2 O.sub.3 P--, phenyl, methylphenyl, methoxyphenyl, dimethylamino, diethylamino, .beta.-hydroxyethylamino, .beta.-hydroxyethoxy, N-phenylureido, N-alkyl.sub.C.sbsb.1.sub.-C.sbsb.4 ureido or N-cycloalkylureido groups or an allyl, 2-methallyl, crotyl or cycloalkyl group, and R.sub.1 and R.sub.2, together with the nitrogen atom, can represent the radical of a heterocyclic saturated or unsaturated ring, or R.sub.1 and R.sub.2 represent a phenyl radical which can be substituted by methyl, ethyl, methoxy, ethoxy, carboxyl or sulfonic acid groups, R.sub.3 denotes a hydrogen atom or an alkyl group of 1 to 4 carbon atoms and which can be substituted by hydroxyl or carboxyl groups, X represents a hydrogen atom or an alkyl or alkoxy group of 1 to 4 carbon atoms, Y represents the vinyl group or the grouping of the formula --CH.sub.2 --CH.sub.2 --Z in which Z denotes an inorganic or organic radical which can be eliminated under alkaline conditions, a represents a number between 0 and 2, b represents a number between 0 and 2 and c represents a number between 1.7 and 2.6, with the proviso that the sum of a, b and c is at most 4, a process for their preparation, and their use for dyeing wool, silk, polyamide fibers, leather or materials containing hydroxyl groups.
