Abstract:
A method of producing silicone-containing aqueous coating compositions which comprises subjecting an aqueous emulsion prepared in advance by emulsification in an aqueous medium containinga polyalkoxypolysiloxane (A) represented by the general formula (1): ##STR4##wherein n represents the mean degree of condensation and is a value of 2 or more, R represents an alkyl, aryl or aralkyl group and the R groups may be the same or different in the number of carbon atoms and may be straight or branched,an unsaturated monomer (B) capable of radical polymerization, the unsaturated monomer (B) excluding an unsaturated monomer (E) containing at least one functional group, which is a hydrolyzable silyl group, a hydroxyl group or an epoxy group,an emulsifier (C) anda hydrolysis inhibitor (F) so as to attain an oil droplet diameter not more than 1,000 nm to polymerization of the unsaturated monomer (B) in the presence of a polymerization initiator (D).
