Patent abstract

Toner compositions include a non cross linked resin; a cross linked resin or gel; a wax; and a colorant. Processes for preparing a toner include mixing a non-cross linked resin and a cross-linked resin or gel in the presence of a wax, a colorant, and a coagulant to provide toner size aggregates; adding additional non-cross linked latex to the formed aggregates thereby providing a shell over the formed aggregates; heating the shell covered aggregates to form toner; and, optionally, isolating the toner.
