description PROBLEM TO BE SOLVED: To obtain a primer composition for fixing a thin titanium oxide film even on e.g. a polyvinyl chloride or ethylene/tetrafluoroethylene copolymer substrate having a hydrophobic surface by mixing a tetraalkoxytitanium with a tetraalkoxysilane and an alkyl silicate for fixing photocatalytic titanium oxide particles on a plastic substrate. SOLUTION: The tetraalkoxytitanium used is desirably tetramethoxytitanium, tetraethoxytitanium or the like. The tetraalkoxysilane used is desirably tetramethoxysilane, tetraethoxysilane, tetrabutoxysilane or the like. The alkyl silicate used is methyl silicate, ethyl silicate, methylethyl silicate or the like. The photocatalytic titanium oxide is a crystalline titanium oxide which can generate conduction elections and positive holes upon excitation with high and is desirably anatase or rutile titanium oxide. The primer composition is applied to the surface of a plastic film and is cured by heat treatment or standing at ordinary temperature.
