Abstract:
A non-aqueous inkjet ink includes 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)An- 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; the polymeric dispersant fulfills the conditions of: WTPOAC>57 and NAmide≧65 mol % wherein WTPOAC represents the ratio of the weight percentage of TPOAC-chains over the weight percentage of amide bonds in the polymeric dispersant; NAmide represents the mol % of amide bonds based on the total nitrogen content of the polymeric dispersant; and the values of WTPOAC and NAmide 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 CH3COOH:THF (14.5:0.5) with 0.1N aqueous perchloric acid.
