     Toner Preparation 
     Although toners can be prepared by the conventional extrusion and jetting process, since these resins are emulsifiable in water, an emulsion coalescence route was selected. 
     EXAMPLES XIII TO XVIII 
     Six toners comprised of 4 percent (percent by weight) of a cyan pigment, available from Sun Chemicals as FLEXIVERSE PB 15:3™, and 96 percent by weight of the sulfopolyester-siloxanes of Examples I to VI were prepared by the following procedure; tabulated in Table B are the toners measured respective particle size, GSD and glass transition temperature. 
     To a 4 liter glass kettle equipped with a mechanical stirrer and heating mantle were added 2.4 liters of a 10 percent by weight of the sulfopolyester-siloxane emulsion of Examples I to VI (Table B), and 22.85 grams of cyan pigment, available as a 42 percent pigment dispersion in water and obtained from Sun Chemicals as FLEXIVERSE PB 15:3™. The resulting mixture was then heated to 56° C. and stirred at 250 revolutions per minute. To this was then added using a pump and over a 5 hour period 1 liter of an aqueous solution comprised of 5 percent by weight of zinc acetate. The mixture resulting was then heated at 56° C. for an additional 2 hours, and then left to cool to room temperature, about 22° C. to 25° C., overnight, about 18 to about 20 hours. The toner product was then filtered off, and washed two times by re-suspending it in 4 liters of water; stirred for 2 hours and refiltered. The filtered toner products were then dried using a fluid bed drier. Each of the dry toners were then characterized by a differential scanning calorimeter.

     Unfused images were generated with the above toners on Xerox Colour Expression (CX) paper. Excellent images were achieved with a developer comprised of the above toners and a Xerox carrier 9700MICR comprised of, for example, a core of iron or steel, and thereover a coating of a polymethyl methacrylate, 40 weight percent, and polyvinylidene fluoride, 60 weight percent, and wherein the toners had added thereto 4 percent silica, available as AEROSIL™ from Degussa Chemicals, 2.3 percent by weight of titanium oxide SMT5103™ and 0.3 percent of zinc stearate. 
     The images were then fused using the Xerox DC2006 printer which contains no oil on the fuser rolls. The toners of Examples XIII to XVIII displayed hot offset temperatures (HOT) between about 150° C. and about 160° C.; acceptable gloss, for example about or in excess of 50 ggu (Gardener gloss units), was achieved, the minimum fix temperatures was about 135° C. to about 140° C. for all toners.
