Abstract

A non-aqueous inkjet ink comprising a benzimidazolone pigment and a polymeric dispersant according to Formula (I): wherein, T represents hydrogen or a polymerization terminating group; Z represents the residue of polyethyleneimine having a number-average molecular weight of at least 100; A represents an oxyalkylene carbonyl group; T-C(O)A n - represents a TPOAC-chain which is bound to Z through an amide bond; and n and m are integers wherein m is at least 2 and n is from 2 to 100; characterized in that the polymeric dispersant fulfills the conditions of: W TPOAC > 57 ¢ and N Amide § 65 mol % with W TPOAC representing the ratio of the weight percentage of TPOAC-chains over the weight percentage of amide bonds in the polymeric dispersant; N Amide representing the mol% of amide bonds based on the total nitrogen content of the polymeric dispersant; and wherein the values of W TPOAC and N Amide are calculated from the total nitrogen content determined by dry combustion of the polymeric dispersant and from the amine content determined through potentiometric titration in a mixture of CH 3 COOH:THF (14.5:0.5) with 0.1 N aqueous perchloric acid.
