METHOD FOR PREPARING LATEX POLYMER, AND METHOD FOR PRODUCING TONER FOR DEVELOPING ELECTROSTATICALLY CHARGED IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a latex polymer with a controlled particle size, and to provide a method for producing a toner for developing an electrostatically charged image. SOLUTION: The method for preparing a latex polymer comprises forming the latex polymer by post-adding unsaturated aliphatic carboxylates having a hydrophilic group in an ester group in a monomer structural formula to a seed polymer obtained by polymerization to complete the emulsion polymerization. The latex polymer obtained from the above method for preparing the latex polymer is used as a resin particulate to produce a toner for developing an electrically charged image.
