Abstract
Abstract The novel copper phthalocyanine dyestuffs of the formula (I) ##STR1## in which CuPc represents a copper phthalocyanine radical, W represents branched or straight-chain C 9-16 -alkylene, a represents 2 to 4, b represents 0 to 2, and the sum of a and b is 3 to 4, are suitable for dyeing and printing cellulose-coating materials and for producing printing inks, in particular for ink-jet printing systems.
