Preparation and characterization of multi-component composite microspheres used for ceramic toner

Abstract

The multi-component composite microspheres of styrene-butyl acrylate resin co-encapsulated Pigment Yellow 53 (PY53), charge control agent (CCA) and paraffin wax for yellow ceramic toner were prepared by suspension polymerization method. The crystal structure, morphology, particle size, thermal properties and color performance of the composite microspheres were characterized by different analytical techniques. The results show that the pigment content had little effect on the glass transition temperature (Tg) of the composite microspheres, and the Tg was about 56 °C, which fits the thermal property of ceramic toner. When the PY53 content was moderate, the composite microspheres owned regular morphology, smooth surface and narrow particle size distribution. As the PY53 content increased, the L* value of the composite particles decreased, and the yellow value (b*) and the color saturation (C*) became larger. When the PY53 content was 2.0 g, comprehensive properties of the composite microspheres were the best.
