Abstract
A process for the preparation of toner compositions which comprises mixing at least one resin monomer with a polymerization initiator, a crosslinking component and a chain transfer component; effecting bulk polymerization until partial polymerization to near the onset of the gel-effect has been accomplished thereby forming an organic phase containing a partially polymerized component; mixing the aforementioned partially polymerized component organic phase with pigment or dye particles; dispersing the resulting organic phase in water containing a stabilizing component whereby there is obtained a suspension of toner particles in water; and polymerizing the toner suspension by heating.
