Patent ID: 8828637

Claim:
An emulsion aggregation toner comprising: a core particle comprising at least one amorphous polyester resin, at least one crystalline polyster resin, and one or more optional ingredients selected from the group consisting of an optional colorant, an optional wax and combinations thereof; and a partially crosslinked polyester shell resin encapsulating aggregated core particles comprising at least one amorphous resin selected from the group consisting of poly(propoxylated bisphenol co-fumarate), poly(ethoxylated bisphenol co-fumarate), poly(butyloxylated bisphenol co-funmarate), poly(co-propoxylated bisphenol co-ethoxylated bisphenol co-finnarate), poly(1,2-propylene fumarate), poly(propoxylated bisphenol co-maleate), poly(ethoxviated bisphenol co-maleate), poly(butyloxylated bisphenol co-maleate), poly(co-propoxylated bisphenol co-ethoxylated bisphenol co-maleate), poly(1,2-propylene maleate), poly(propoxylated bisphenol co-itaconate), poly(ethoxylated bisphenol co itaconate), poly(butyloxylated bisphenol co-itaconate), poly(co-propoxylated bisphenol co-ethoxylated bisphenol co-itaconate), poly(1,2-propylene itaconate), and combinations thereof, wherein about 5 wt % to about 35 wt % of the amorphous resin is crosslinked, wherein the viscosity of the shell is greater than the viscosity of the core, and wherein the toner exhibits a viscosity plateau at higher temperatures as compared to a toner without said polyester gel in the shell, and gloss of said toner is from about 20 ggu to about 100 ggu.
