(57) [Summary] [Problem] It is excellent in storage stability, and has an excellent balance of performance such as adhesion, water resistance, organic chemical resistance, stain resistance, weather resistance, frost resistance, and is transparent and has high hardness. Provided are an aqueous dispersion capable of forming a coating film, a method for producing the same, and a coated body. SOLUTION: The method for producing an aqueous dispersion comprises, in an aqueous medium, (A) an organosilane such as methyltrimethoxysilane or dimethyldimethoxysilane or a partial condensate thereof; (B) radical polymerizable monomer, (C) emulsifier, (D) The hydrolysis catalyst of component (A) and the compound having an ultraviolet absorbing and / or light stabilizing effect of component (A) are mixed and emulsified to promote the hydrolysis of component (A) and to make the emulsion finer. (E) A radical polymerization initiator is added to promote the hydrolysis / condensation reaction of the component (A) and the polymerization reaction of the component (B). The aqueous dispersion comprises an aqueous dispersion of composite polymer particles obtained by the above method. |
