Block copolymers synthesized with TERP were utilized as pigment dispersants for inkjet ink. The dispersants gave better dispersion stability compared with a commercial dispersant especially in case of magenta, which is generally difficult to be dispersed (Figure 1). Moreover much better redispersibility of the dried ink was observed, which leads to keeping ink from blocking a nozzle of inkjet print head (Figure 2). Its printed ink was also improved in terms of stability against friction (no data here). It is likely that the above features come from the block structure of the polymers. Further detailed data will be shown on the meeting.,
