Preparation of encapsulated disperse dye dispersion for polyester inkjet printing ink

Abstract

Abstract Encapsulated C.I. disperse dye blue 60 (disperse dye) was prepared with poly(styrene‐maleic acid) via phase separation method, followed by the preparation of dispersion and inkjet printing ink. The results showed that the encapsulated disperse dye dispersion had a small particle size, narrow particle size distribution, and excellent stability to centrifugal force, freeze‐thaw treatment, polyols and alkali and its rheological behavior belong to Newtonian fluid. The ink that prepared using this dispersion satisfied with the requirement of Mimaki JV4‐180 and showed an excellent printing performance at room temperature. © 2011 Wiley Periodicals, Inc.
