  • Emulsion particle, emulsion comprising same, method for manufacturing emulsion
    Patent number: 11046821
    Abstract: An emulsion particle, an emulsion including the same, and a method of manufacturing an emulsion are provided. The emulsion particle includes: a core derived from a polymer of an unsaturated ethylenic monomer and including a first sub core and a second sub core surrounding the first sub core; and a shell surrounding the core and including an alkali-soluble resin, wherein the first sub core includes a polymer having a first glass transition temperature, and the second sub core includes a polymer having a second glass transition temperature lower than the first glass transition temperature.
    Type: Grant
