A water-base silicone-modified acrylate polymer emulsion produced by emulsion-polymerizing a monomer system (A) containing an acrylate monomer selected from the group consisting of acrylic esters, methacrylate esters and mixtures thereof in an aqueous medium in the presence of an emulsifier (B) selected from the group consisting of ethylenic monomers having a sulfo or sulfonate group, ethylenic monomers having a sulfuric ester group, and mixtures thereof, and modifying the obtained acrylate polymer emulsion with a specified modifier (C) having a silicone structure during or after the polymerization. The obtained emulsion can form a coating film excellent in water repellency, water resistance, weathering resistance, pigment dispersion, retention of luster, staining resistance, and close contact. Hence, it is useful as a coating material, prime coating or finishing material for construction materials, adhesive, pressure-sensitive adhesive, paper coating material or textile finishing material, in particular, as a coating material and a finishing material for construction materials. |
