Latest Patents
Hirata's latest patents include a method for the manufacture of colored particles. This method aims to produce colored particles with an average grain size of 10-200 µm simply, efficiently, and in high yields. The process involves mixing water-insoluble particles with a polyvalent carboxylic acid resin, followed by the addition of a dispersion-stabilized emulsion resin containing a colored pigment. The result is colored particles with a surface colored coating, ideal for creating finely detailed, marble-like, multi-color patterns. Another patent focuses on the dispersion of colored high-molecular particulate material, which is prepared by mixing a pigment with an aqueous emulsion of resin and combining it with polyvinyl chloride particles. This innovative approach results in a film comprising the resin and pigment formed on the particles.
