To provide a water borne compsn. with an excellent storing stability and coating hardness, and furnishing the coating further with an excellent water resistance, water repellency, stain resistance, flexibility and adhesion to a substrate.
This compsn. is prepd. by dissolving or dispersing, into an aq. dispersion of a polymer, a silicone copolymer comprising, as monomeric units, an alkoxysilyl group-containing radically polymerizable monomer, a carboxyl group-containing radically polymerizable monomer, a silicone macromonomer having one or two vinyl polymerizable groups at one or both of molecular terminals, and optionally a radically polymerizable monomer copolymerizable with any of the above monomers wherein by a part or the whole of the carboxyl group in the copolymer is neutralized.
