Abstract

Basic copper phthalocyanine dyestuffs of the general formula ##STR1## in which Cu-Pc denotes the radical of an m+n-valent copper phthalocyanine radical, PA1 A denotes alkylene PA1 B denotes a radical of the formula ##STR2## R.sub.1 denotes hydrogen or alkyl, R.sub.2, R.sub.3 and R.sub.4, independently of one another, denote alkyl which can be substituted by hydroxyl or alkoxy groups, PA1 R.sub.5 denotes hydrogen, alkyl or aminoalkyl, PA1 R.sub.6 and R.sub.7, independently of each other, denote hydrogen or alkyl which can be substituted by hydroxyl, alkoxy or amino groups, and PA1 R.sub.8 denotes hydrogen or alkyl, or PA1 R.sub.1 can form a closed ring with R.sub.2, PA1 R.sub.2 can form a closed ring with R.sub.3, PA1 R.sub.5 can form a closed ring with R.sub.6 and/or PA1 R.sub.6 can form a closed ring with R.sub.7, PA1 m denotes a number from 1.0 to 2.5, PA1 n denotes a number from 0 to 1.4, where PA1 m+n is 1.8 to 2.5, PA1 p denotes 0, 1, 2 or 3 and PA1 X.sup.(-) denotes an anion, are used for dyeing paper.
