Coloured particles by dispersion polymerization

Abstract

Coloured particles have been prepared by dispersion copolymerization of colourless vinyl monomers and polymerizable anthraquinone dyes. The dyes were synthesized by condensation of methacryloyl chloride and amino- or hydroxy-substituted anthraquinones. This paper describes the formation by dispersion polymerization of coloured copolymer particles of diameter greater than 5 microns. The coloured particles were characterized by size, visible absorption spectra, and solution properties of the copolymers. © 1987.
