Abstract:
1. A coating composition, comprising: an aggregate and an emulsion composition comprising a polymer particle dispersed in an aqueous medium, wherein the polymer particle comprises: (A) 40% to 95% by mass of a structural unit formed by polymerizing an alkyl (meth)acrylate monomer having an alkyl group with 4 to 14 carbon atoms, (B) 0.1% to 5% by mass of a structural unit formed by polymerizing an ethylenically unsaturated carboxylic acid monomer, (C) 1% to 20% by mass of a structural unit formed by polymerizing a vinyl monomer having a cyano group, (D) 1% to 20% by mass of a structural unit formed by polymerizing a monomer which is a reaction product of a (meth)acrylic acid and a monofunctional epoxy compound, and (E) 0% to 50% by mass of a structural unit formed by polymerizing another monomer which is capable of copolymerizing with at least one compound among said monomers, based on 100% by mass of a total of said structural unit (A), said structural unit (B), said structural unit (C), said structural unit (D), and said structural unit (E); wherein the monomer that is polymerized to form the structural unit (D) is at least one compound selected from the group consisting of 2-hydroxy-3-phenoxypropyl acrylate and 2-hydroxy-3-p-methylphenoxypropyl acrylate; wherein the other monomer that is polymerized to form the structural unit (E) is at least one compound selected from the group consisting of an alkyl (meth)acrylate monomer having an alkyl group with 1 to 3 carbon atoms, a vinyl monomer having a hydroxyl group, a vinyl monomer having an amino group, a vinyl monomer having an amide group, a vinyl monomer having an alkoxyl group, an aromatic vinyl monomer, a conjugated diene monomer, a maleimide monomer, a vinylester monomer, a vinylether monomer, a vinyl monomer having a glycidyl group, an unsaturated dicarboxylic acid monoalkyl ester, an unsaturated dicarboxylic acid dialkyl ester, and a monomer having a silicon-containing group; and wherein the coating composition is suitable for thick coating.
