Abstract
The present disclosure relates to a toner process comprising providing a resin miniemulsion comprising polymeric particles comprising at least one free radical polymerizable monomer compound and at least one alkylene anhydride; blending the miniemulsion with at least one colorant, at least one amine, and optionally at least one wax; heating the resulting mixture below or about equal to the glass transition temperature (Tg) of the resin emulsion; and heating the resulting mixture above or about equal to the glass transition temperature (Tg) of the resin emulsion.
Claims4
A toner process comprising:
- providing a resin miniemulsion comprising polymeric particles comprising at least one free radical polymerizable monomer compound and at least one alkylene anhydride;
- and a surfactant;
- blending the miniemulsion with at least one colorant, at least one amine to aggregate and coalesce the polymeric particles, and optionally at least one wax;
- heating the resulting mixture below or equal to the glass transition temperature (Tg) of the resin emulsion;
- and heating the resulting mixture above or about equal to the glass transition temperature (Tg) of the resin emulsion,
- wherein the at least one amine is selected from the group consisting of polyoxypropylenediamine, N-isopropyl-N′-phenyl-phenylene diamine, N-(1,3-dimethylbutyl)-N′-phenyl-phenylene-diamine, N,N′-di(2-octyl)-4-phenylene diamine, N, N′-bis(1,4-dimethylpentyl)-4-phenylene diamine, and dihydroxy tetraphenyl biphenylene diamine, and
- wherein the at least one amine is present in the miniemulsion in an amount of from about 0.5 to about 10% by weight relative to the amount of the polymeric particles.
