Abstract
Abstract A water-soluble dye, free from cellulose reactive groups, of the formula: wherein R' is -(C a H 2a O) m (C b H 2b O) n H. R 2 is H or -(C a H 2a O) m ,(C b H 2b O) n H, or R' & R 2 together with the nitrogen atom form a morpholine ring a & b are different and from 1 to 8 m is from 1 to 10; n is from 0 to 9; q is ½ or 1 p is 1 or 2 L is a transition metal capable of complexing with a dye M is H, ammonium, or a monovalent metal; B, D, F & E are H or substituents; X is NR 'R 2 , NR 3 R 4 , -NR 3 -Z-NR 4 -, OR 3 , or the residue of a mono- or dis-azo chromophore comprising benzene, naphthalene or hetero-mono- or bi- cyclic diazo and coupling components, linked to the triazine nucleus through a primary or secondary amino linking group in which R 3 and R 4 are each independently H, alkyl or aryl; and Z is a divalent linking group; suitable for use in the preparation of a printing ink, especially for ink jet printing.
