ABSTRACT OF THE DISCLOSURE Disclosed is a process for producing thin films, which comprises dispersing or dissolving inorganic substance or hydrophobic organic substance in an aqueous medium in the presence of a surfactant having HLB value of 10 to 20, to obtain micelle solution or dispersion, dipping a semiconductive or photoconductive substrate into said micelle solution or dispersion, applying an electric potential on said substrate if necessary, and irradiating lights on the contact interface of said mecelle solution or dispersion and said substrate, and thus forming thin films of said inorganic substance or hydrophobic inorganic substance on said substrate. Also disclosed is a process for producing color filters having excellent properties, which comprises forming color separation filter on the substrate according to the above- mentioned process, by the use of pigments or dyes in three primary colors of red, green, and blue.
