Ink toner particles with controlled surface morphology |
摘要 |
The present invention provides a process for producing a colored toner having a textured surface, the process includes forming a polymer composition of at least one polymer and a colorant, where the at least one polymer has a softening temperature from about 60° C. to about 160° C.; forming an aqueous mineral suspension of at least one multivalent metal phosphate; forming a dispersion by combining the polymer composition and the aqueous mineral suspension under agitation to form a solid portion comprising dispersed particles of the polymer composition; heating the dispersion to a temperature above a glass transition temperature (Tg) of the polymer composition and increasing the pH to above 7.0; cooling the dispersion including the dispersed particles of the polymer composition to a temperature of from about 1° C. to about 89° C.; and recovering the particles. |
