摘要

Water-soluble fibre-reactive green phthalocyanineazo dyestuffs of the formula I IMAGE where Pc is the radical of a phthalocyanine, B is a divalent aliphatic or aromatic radical, D and D' are each divalent aromatic radicals, A and y are each are each fibre-reactive radicals, het and X are each divalent bridge members, R1 and R1' are each hydrogen or monovalent aliphatic or aromatic radicals, R2 and R3 are each hydrogen or monohydric aliphatic radicals, k is 1, 2 or 3; g is 0 or 1; m is 1, 2 or 3; n is 0 or 1 and p is 0 or 1, with k + g + m being 3 or 4 and n + p being 1, and their alkali metal, ammonium or alkaline earth metal salts, their preparation by coupling a diazotised amine of the formula II IMAGE a pyrazolone of the general formula III IMAGE where in each case the variable radicals and indices are as defined above or, if p is 0, by acylation of a dye of the formula I a IMAGE wherein the variable radicals and indices are each as defined above, with a chloride of the formula IV C1-A (IV) where A is as defined above, their use for dyeing and printing textiles consisting of or containing fibres of wool, polyamide or cellulose, and also pyrazolones of the formula III and their preparation by coupling a diazotised amine of the formula V b IMAGE where the variable radicals and indices are each as defined above and M is het R1' or C1, with a succinic acid derivative of the formula VI IMAGE where R3' and R3'' each have the meanings mentioned above for R3 other than hydrogen and Z is hydrogen, alkyl, phenyl or alkoxycarbonyl, alkaline cyclisation of the resulting hydrazone to give a pyrazolone, optional hydrolysis of the ester group -COOR3' and, if M is C1, reaction of the pyrazolone with a compound of the formula H-het-R1'.R
