[PROBLEMS] To provide an aqueous coating composition which forms a coating film which is hardly wetted by water on buildings, automobiles, glass, paper, industrial products and the like, and in which attached water droplets easily slide off. (A) (a) 3 to 70% by weight of a monomer having a polysiloxane group, and (b) α having one kind of functional group selected from the group consisting of a carboxyl group, a sulfonic acid group and an amino group. A monomer mixture containing 1 to 25% by weight of an .alpha.,. Beta.-ethylenically unsaturated monomer and (c) 5 to 96% by weight of another copolymerizable .alpha.,. Beta.-ethylenically unsaturated monomer. Aqueous solution or aqueous dispersion of a copolymer obtained by copolymerizing And (B) a reaction product of (g) an epoxy-terminated siloxane polymer and (h) an acid compound. |
