  • Resin emulsion for coating materials
    Patent number: 11203699
    Abstract: A resin emulsion for a coating material, which contains emulsion particles each having an inner layer and an outer layer, and wherein: each emulsion particle has a resin layer containing a polymer (I) that is obtained by emulsion polymerizing a monomer component A containing 80 to 100% by mass of a styrene monomer and 0 to 20% by mass of a monomer other than the styrene monomer and a resin layer containing a polymer (II) that is obtained by emulsion polymerizing a monomer component B containing 70 to 100% by mass of a (meth)acrylic acid ester and 0 to 30% by mass of a monomer other than the (meth)acrylic acid ester; and the content of the styrene monomer in all monomer components used as starting materials for the emulsion particles is 10 to 55% by mass.
    Type: Grant
    Filed: September 16, 2016
    Date of Patent: December 21, 2021
    Assignee: NIPPON SHOKUBAI CO., LTD.
    Inventors: Kanji Nakao, Yoshiaki Kuramochi
