Abstract:
1. A process comprising; contacting a latex with compounds consisting of a separate carboxylic acid and a stabilizer of the following formula: wherein R1 is a hydrogen or methyl group; R2 and R3 are independently selected from alkyl groups containing about 1 to about 12 carbon atoms and a phenyl group; and n is from about 0 to about 20; recovering a resulting latex resin, wherein when said latex is contacted with said stabilizer in the absence of said separate carboxylic acid, a resin of larger particle size is produced, and when said latex is contacted with said stabilizer and with said separate carboxylic acid, a resin of smaller particle size is produced; and contacting the latex resin with a colorant dispersion, and an optional wax dispersion to form toner particles having a volume average diameter of from about 2 micros to about 10 microns, and a circularity from about 0.9 to about 0.99, wherein the carboxylic acid is present in an amount of from about 0.001% to about 10% by weight of the latex.
