Zusammenfassung:The present invention relates generally to methods to make a chemically prepared toner having a core shell structure for use in electrophotography and more particularly to a method to make an emulsion aggregation chemically prepared core shell toner formulation using a styrene acrylic polyester copolymer for the shell. The styrene acrylic polyester copolymer has a glass transition temperature (Tg) between 55° C. to 65° C., a melt temperature (Tm) between 100° C. to 130° C., a peak molecular weight of about 12,000 and acid value from 10-28.
