<p>PROBLEM TO BE SOLVED: To provide a photocatalyst functional film having a photocatalytic function layer excellent in transparency or strength and useful for long-term outdoor use as an agricultural film or a window protective film. SOLUTION: In a photocatalytically functional laminated film, a photocatalytic function layer comprising a compsn. containing titanium oxide with a mean particle size of 0.001-0.5μm and a hydrolysate of a hydrolyzable silicon compd. represented by formula (wherein n is an integer of 0-8 and X1, X2, X3 and X4 are a halogen atom or a 1-8C alkoxy group and may be same or different) is provided on at least the single surface of a base material film. In this case, a glass plate is bonded to the surface opposite to the surface of the photocatalytic function layer of the laminated film and the haze change of the photocatalytic function layer after the surface of this layer irradiated with light for 1,000 hr by a sunshine weather meter is set to below 4%.</p> |
