A water-soluble dye, free from cellulose-reactive groups, of the formula:
wherein R' 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;
M is H, ammonium or a monovalent metal;
X is (i) NR1R2, (ii) NR3R4, in which R3 and R4 are each independently selected from H, alkyl and aryl, or (iii) a mono- or dis-azo chromophore comprising benzene, naphthalene or mono- or bi-cyclic heteroaryl diazo and coupling components linked to the triazine nucleus through an amino linking group;
R5 & R6 are selected from S03M and H provided at least one is S03M;
R7 is H, halogen, C1-4 alkyl, C1-4 alkoxy, SO3M or COOM; and R8 is H or S03M, a printing ink containing the dye and a method of printing.
