    • Phthalocyanine dyestuffs of the formula ##STR1## wherein Pc denotes the radical of a copper phthalocyanine or nickel phthalocyanine,R.sub.1, R.sub.2, R.sub.3 and R.sub.4 denote hydrogen or alkyl,Z denotes ##STR2## wherein R.sub.5 and R.sub.6 denote H or a hydrocarbon radical,R.sub.7 denotes H or Cl andR.sub.8 denotes H, F or CH.sub.3, anda denotes a number from 1 to 3,b denotes a number from 0 to 2,c denotes a number from 1 to 2 anda+b+c.ltoreq.4,are obtained in a particularly advantageous manner when compounds of the formula ##STR3## wherein p denotes a number from 0.5 to 1.8,q denotes a number from 1.2 to 3.5 andp+q=2 to 4,are reacted with c mols of a compound of the formula ##STR4## and, if appropriate, b mols of an amine of the formula ##STR5## the acylamino group is split off and the resulting phthalocyanine dyestuff is reacted with c mols of a compound from which the radical of the formula A or B is derived.
    • 其中Pc表示铜酞菁或镍酞菁的基团,R 1,R 2,R 3和R 4表示氢或烷基,Z表示其中R 5和R 6表示H或烃基,R 7 表示H或Cl,R8表示H,F或CH3,a表示1〜3的数,b表示0〜2的数,c表示1〜2的数,a + b + c = 4 当其中p表示0.5至1.8的数字时,q表示1.2至3的数字,其特别有利地获得。
