Abstract

Described is an acrylic resin emulsion, a method for preparing the acrylic resin emulsion, and a coating composition. The present invention provides an acrylic resin emulsion comprising: an acrylic resin, which is a polymerized product of (A) 20 to 80 parts by mass of a polymerizable group-containing triorganosilyl ester monomer, (B) 20 to 80 parts by mass of a (meth) acrylic acid alkyl ester monomer having no functional group, and (C) 0 to 60 parts by mass of a polymerizable group and functional group-containing monomer other than components (A) and (B), provided that a total mass of said components (A) to (C) is 100 parts by mass; and (D) 5 to 70 parts by mass of a polymeric emulsifier having a number average molecular weight of 1,000 or more, relative to the total 100 parts by mass of said components (A) to (C); and water.
