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.

Claim (Index 25):
A method for producing a resin emulsion for a top coating material, comprising:\n carrying out an emulsion polymerization of a monomer component A comprising 80 to 100% by mass of a styrene-based monomer and 0 to 20% by mass of a monomer other than the styrene-based monomer, to form a resin layer comprising the polymer (I) as an inner resin layer, thereafter carrying out an emulsion polymerization of a monomer component B comprising 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, to form a resin layer comprising the polymer (II) as an outer resin layer, and adjusting the content of the styrene-based monomer to 10 to 55% by mass of the total monomer components used as raw materials of the emulsion particle when carrying out the emulsion polymerizations, wherein the total monomer components used as raw materials of the emulsion particle comprise an acid group-containing monomer, and the content of the acid group-containing monomer is 0.1 to 10% by mass of the total monomer components.
