PROBLEM TO BE SOLVED: To provide an aerosol composition containing a powder having a photocatalytic effect, which is injected over a specific coating film to dissolve (to fluidize) its surface, wherein the photocatalytic effect is successfully maintained in a long period since the powder is easily adhered to the surface of the coating film and hardly comes off from the film after the solvent dries. SOLUTION: The aerosol composition comprises a powder having a photocatalytic effect, a solvent having the solubility parameter of 7-15 and a liquified gas. Furthermore, the solubility parameter of the above solvent is preferably 8-12.5. The powder having the photocatalytic effect is titanium oxide. COPYRIGHT: (C)2005,JPO&NCIPI
