Abstract
A method of producing silicone-containing aqueous coating compositions excellent in shelf stability of the emulsion and in weather resistance, stain resistance, water resistance and solvent resistance of coatings derived therefrom is provided. The method comprises subjecting an aqueous emulsion prepared in advance by emulsification in an aqueous medium containing a polyalkoxypolysiloxane (A), an unsaturated monomer (B) and an emulsifier (C) so as to attain an oil droplet diameter not more than 1,000 nm to polymerization in the presence of a polymerization initiator (D).
