The present invention is a composite coating film in which an organic material is compounded in a matrix of an inorganic material, wherein the coating film has a hollow structure with regularity, and an organic inorganic composite in which a hemispherical uneven pattern is formed on the surface of the coating film. The large-area structural color film obtained by baking a coating film and its composite coating film is provided. An organic-inorganic composite coating film is obtained by applying a metal alkoxide, an aqueous dispersion of monodisperse hollow polymer particles, and an aqueous coating composition containing an acid catalyst on the substrate, followed by curing, and firing this to obtain a structural color film.n n n n Structural color film, organic inorganic composite coating film |
