PROBLEM TO BE SOLVED: To provide an anatase type titanium oxide-containing composite film for interior use that has a photocatalytic activity and produces active oxygen even for visible light or weak light beam, has a self-cleaning capability, as well as in which the invasive action by active oxygen on the interior surface is effectively shielded.SOLUTION: An anatase type titanium oxide-containing composite film for interior use is characterized in being formed by: preparing a liquid A of peroxotitanic acid solution; preparing a liquid B by heating said liquid A to 70 to 200°C to produce an anatase type titanium oxide fluid dispersion, and adding thereto a noble metal salt or nano-colloid; and applying liquid A to the interior surface of a structure, and upon drying and on top of thereon applying a mixture obtained by mixing said liquid A and liquid B, followed by drying.SELECTED DRAWING: None |
