摘要: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex in forming a seed resin or a master batch which, in turn, may be utilized to form latex resins and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.

摘要: The latex of an emulsion aggregation toner is prepared without the use of a surfactant. The process comprises preparing an emulsion of monomers in water without a surfactant; adding a free radical initiator to at least a portion of the emulsion to initiate seed polymerization to form seed polymer, wherein the free radical initiator attaches to the seed polymer to form ionic, hydrophilic end groups on the seed polymer; and adding additional monomer to the composition to complete polymerization to form a latex polymer.
