A water-soluble dye, free from cellulose reactive groups, of the formula: <IMAGE> wherein R1 is -(CaH2aO)m(CbH2bO)nH, R2 is H or -(CaH2aO)m(CbH2bO)nH, or R1 & R2 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 1/2 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 NR1R2, NR3R4, -NR3-Z-NR4-, OR3, 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 R3 and R4 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. |
