Abstract
A process for the preparation of toner compositions comprising: forming a mixture comprised of at least one free radical reactive monomer, a colorant, a stabilizer compound containing a stable free radical reactive group, and a liquid vehicle; and heating the mixture from about 75.degree. to about 200.degree. C. to effect polymerization of said monomer, wherein there results stabilized core resin particles containing said colorant and wherein said stabilized core particles are stabilized by said stable free radical reactive stabilizer compounds being bonded directly to the core particles.
