Abstract
A composition for forming a transparent film, comprising photocatalytic particles; zirconium ammonium carbonate; a cohydrolysis-polycondensation product of an aluminum alkoxide represented by the formula Al(OR)3 where R is an organic group and a titanium alkoxide represented by the formula Ti(OR′)4 where R′ is an organic group; and water, and having a pH of 7 to 9.
Claims21
A composition for forming a transparent film, comprising photocatalytic particles;
- zirconium ammonium carbonate in an amount of 0.1 mass % to 0.75 mass %;
- a cohydrolysis-polycondensation product of an aluminum alkoxide represented by the formula Al(OR)3 where R is an organic group and a titanium alkoxide represented by the formula Ti(OR′)4 where R′ is an organic group in an amount of 0.1 mass % to 1 mass % as reduced to Al2O3 and in an amount of 0.01 mass % to 0.1 mass % as reduced to TiO2;
- and water, and having a pH of 7 to 9, wherein said composition being able to be cured at 10 to 20° C. to form a transparent film.
