Abstract:
A method of making photocatalyst contained coating films comprising the steps of providing a coating film of the composition (i) or (ii) on the surface of an organic film and providing a coating film of the composition (I) or (II) on the coating film, wherein:the composition (i) is a coating composition containing at least one component (a) selected from organosilanes, hydrolyzates of the organosilanes, and condensates of the organosilanes represented by Formula 1 (R1)nSi(OR2)4âˆ’nâ€ƒâ€ƒ(1) (wherein, R1 is a monovalent organic group having 1 to 8 carbon atoms; when two exist, they are either identical to or different from each other; R2 is an alkyl group having 1 to 5 carbon atoms or an acyl group having 1 to 6 carbon atoms: when two exist, they are either identical to or different from each other; and n is an integer ranging from 0 to 2);the composition (ii) is a coating composition containing the component (a) and a polymer component (b) having a silyl group having silicon atoms bonded with a hydrolytic group and/or a hydroxy group; the composition (I) is a coating composition containing the component (a) and a photocatalyst (c); and the composition (II) is a coating composition containing the component (a), the polymer component (b), and the photocatalyst (c).
