To provide a coating film formed of an aqueous coating composition which is superior in weatherability and stain resistance to the coating film to be formed of the conventional aqueous coating and has flexibility capable of sufficiently coping with the movement of a structure.
The coating film is formed of an aqueous coating composition having, as the main component, a water dispersion type binder obtained by dispersing composite particle bodies having a particle diameter of 20-200 nm obtained by compounding synthetic resin particles with inorganic solid particles into water, and the above inorganic solid particles are interspersed in the interface of the surface of the coating film and a material to be coated. Furthermore, in the coating film, an association of three or more of the above inorganic solid particles is interspersed.
