A method of inkjet printing an image onto a substrate comprising applying to the substrate a composition comprising a liquid medium, a pigment and a polymer comprising a chain of formula (1) or a salt thereof: (1) Wherein each X is independently an alkyl, aryl, or heterocyclyl group each of which may be optionally substituted; Q 1 and Q 2 respectively Is independently NR 1 , O or S; Wherein each R 1 is independently H or optionally substituted alkyl, aryl, or heterocyclyl group; Each A is independently an optionally substituted divalent organic linking group; n is 2 to 1000; Each m is independently 1 or 2; In each case when m is 1, Q 3 is independently NR 1 , O or S and each R 1 is independently H or an optionally substituted alkyl, aryl or heterocyclyl group; And when m is 2, Q 3 is N; And The polymer having a chain of formula (1) or a salt thereof is used for grinding the pigment. |
