<p>A process for ink jet printing an image on a substrate comprising applying to the substrate a composition comprising a liquid medium, a pigment and a polymer comprising a chain of the Formula (1) or a salt thereof: Formula (1) wherein: each X independently is an alkyl, aryl, or heterocyclyl group each of which may be optionally substituted each Q1 and Q2 independently is NR1, O or S; wherein each R1 independently is H or an optionally substituted alkyl, aryl or heterocyclyl group; each A independently is an optionally substituted divalent organic linking group; n is from 2 to 1,000 each m independently is 1 or 2; in each case when m is 1, Q3 independently is NR1, O or S and each R1 independently is H or an optionally substituted alkyl, aryl or heterocyclyl group; and when m is 2, Q3 is N; and the polymer having a chain of Formula (1) or salt thereof has been used to comminute the pigment.</p> |
