<p>An aqueous dispersion which is excellent in storage stability, and can form a coating film excellent in leveling properties, anti-checking properties, water resistance, etc., transparent and high in hardness, which is obtained by mixing and emulsifying (A) at least one selected from an organosilane represented by (R<1>)4-n- (Si)-(OR<2>)n, a hydrolysate of the organosilane and a partial condensation product of the hydrolysate, (B) a radical polymerizable monomer, (C) an emulsifier and (D) a hydrolytic catalyst for component (A) to reduce the particle size of an emulsion, as well as to allow hydrolysis of component (A) to proceed, and adding (E) a radical polymerization initiator to allow hydrolysis/condensation reaction of component (A) and polymerization reaction of component (B) to proceed, has a concentration of alcohols having a boiling point of 100 DEG C or less of 0.1 to 2.0 wt%, and further contains (F) a component having ultraviolet absorption and/or light stabilization action as needed.</p> |
