Examples
Embodiment 1
[0067] All samples of Example 1 were generated under ambient air. Mix using a stainless steel spatula. Heating was performed using a Magna-4 hot plate.
[0068] Fill a glass beaker with the indicated amount of polyester polymer. The polyester polymer was heated using a Magna-4 hot plate at setting 5 until the polyester polymer was visibly molten.
[0069] In samples 1 to 7, the specified amount of Ag 2 SO 4 Fill into a beaker containing molten polyester polymer. The molten mixture was stirred for 1 minute. An aliquot of the molten composite was removed from the beaker and spread onto a Teflon plate, then allowed to cool to ambient temperature (22 °C). The resulting solid plaque was removed from the Teflon plate, identified by sample number, and evaluated visually for its color.
[0070] In samples 8 to 11, a specified amount of charge control agent was charged into a beaker containing molten polyester polymer. The melt mixture is mixed until the charge control agent is...
Embodiment 2
[0075] All samples were generated under ambient air. Mixing was performed using a Werner Pfleiderer ZSK30NM9 twin-screw mixer.
[0076] Charge 9.5kg of polyester polymer and 500g of Ag into a steel container 2 SO 4 . Pour the powder mixture into a Henschel mixer and mix for 1 minute. The mixed powders were collected and fed to the mixer at a rate of 15 kg / hour. The resulting extruded polymer sheet was collected as a large flat sheet. The flat tablets were ground using a Cumberland 0GRAN 3KN granulator to produce a coarsely ground powder. The resulting coarsely ground powder is a clear overcoat toner masterbatch. Using ICP, Ag 2 SO 4 The concentration was measured to be 4.6% by weight. With 4.6 wt% Ag 2 SO 4 Example 2 had no significant effect on color.
[0077] The constant charge level of the transparent overcoat toner masterbatch of Example 2 was evaluated using the MECCA apparatus.

[0079] All sustained levels of chargi...
Embodiment 3
[0081] All samples were generated in ambient air. Mix and combine using a two-roll mill.
[0082] Load the specified amount of pre-mixed polyester polymer, charge control agent and Ag into the two-roll mill 2 SO 4 and mix for 15 minutes. The resulting clear toner material was then allowed to cool to room temperature and coarsely ground using a Wiley™ mill with a 2 mm mesh. The coarse ground powder was then jet milled using a TrostTX fluid energy mill. The obtained transparent overcoat toner powder had a median diameter particle diameter measured by a Coulter Counter of 8 to 10 micrometers in volume percent.
[0083] The constant charge level of the transparent overcoat toner powder of Example 3 was evaluated using a MECC apparatus.
[0084]
[0085] All sustained levels of charging metrics for the clear overcoat toner powder of Example 3 demonstrated Ag 2 SO 4 There is no adverse effect on toner particle charging.
