Preparation of Nanoscale Waterborne Disperse Dye Dispersion by Phase Separation Technique for Inkjet Printing Ink
Abstract:C.I. disperse dye blue 60 was encapsulated with poly(styrenemaleic acid) by phase separation method and followed by the preparation of encapsulated disperse dye dispersion. Experimental results showed that sodium hydroxide and ammonia provided the dispersion the smaller particle size as compared with other additives. An optimal process was attained when mass ratio of NaOH to poly(styrene-maleic acid) was about 0.5, mass ratio of SDBS or OP-10 to encapsulated disperse dye was about 15% and dispersed with bead mill or ultrasonic machine. The encapsulated C.I. disperse dye blue 60 dispersion had narrow particle size distribution and excellent stability to centrifugal force, freeze-thaw treatmen. The rheological behavior of the dispersion was close to Newtonian fluid.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
