Monoazo dyes useful in ink compositions for printing on substrates by ink-jet printing
First Claim
1. An ink composition comprising(i) a medium comprising a mixture of water and one or more water-soluble organic solvent(s), an organic solvent, or a low melting point solid;
- and(ii) a dye of Formula (1) or salt thereof;
##STR10## wherein each X1 independently is a labile or non-labile substituent;
each T independently is --O--, --S-- or --NR1 --;
each L1 independently is a divalent organic linker group;
each V1 independently is a group which is capable of undergoing an addition reaction or an elimination and addition reaction;
each R1 independently is H or optionally substituted alkyl;
Z is the residue of a coupling component; and
m and n are each independently 0 or 1.

Abstract
An ink composition comprising
(i) a medium comprising a mixture of water and one or more water-soluble organic solvent(s), an organic solvent, or a low melting point solid; and
(ii) a dye of Formula (1) or salt thereof: ##STR1## wherein: each X1 independently is a labile or non-labile substituent;
each T independently is --O--, --S-- or --NR1 --;
each L1 independently is a divalent organic linker group;
each V1 independently is a group which is capable of undergoing an addition reaction or an elimination and addition reaction;
each R1 independently is H or optionally substituted alkyl;
Z is the residue of a coupling component; and
m and n are each independently 0 or 1.
Also claimed is a composition comprising the ink and a nucleophilic agent; a process for ink jet printing of a substrate wherein the ink is applied to the substrate using an ink jet printer together with a nucelophilic agent and heating and/or basifying the ink and nucelophilic agent thereby causing the dye present in the ink and the nucleophilic agent to react together; and a toner resin composition comprising a toner resin and a dye of Formula (1).
