Water-soluble triazine black dyes from cellulose reactive groups and
suitable for use in inks
摘要:
A water-soluble dye, free from cellulose reactive groups, of the formula: ##STR1## wherein R.sup.1 is --(C.sub.a H.sub.2a O).sub.m (C.sub.b H.sub.2b O).sub.n H,R.sup.2 is H or --(C.sub.a H.sub.2a O).sub.m (C.sub.b H.sub.2b O).sub.n H, orR.sup.1 & R.sup.2 together with the nitrogen atom form a morpholine ringa & b are different and from 1 to 8m is from 1 to 10;n is from 0 to 9;q is 1/2 or 1p is 1 or 2L is a transition metal capable of complexing with a dyeM is H, ammonium, or a monovalent metal;Q is H or SO.sub.3 MT is H or C.sub.1-4 -alkyl;D is a substituted azo group;B, E & F are H or substituents;X is NR.sup.1 R.sup.2, NR.sup.3 R.sup.4, --NR.sup.3 --Z--NR.sup.4 --, Or.sup.3, or the residue of a mono- or bis-azo chromophore comprising benzene, naphthalene or mono- or bi- cyclic heteroaryl diazo and coupling components, linked to the triazine nucleus through a primary or secondary amine linking group, wherein R.sup.3 & R.sup.4 each independantly are H, alkyl or aryl; andZ is a divalent linking group;a mixture of this dye with an unmetallized orange dye of similar structure and an ink derived from the dye or dye mixture which is suitable for use in printing, especially ink jet printing.
