- Fig. 5 shows the XPS measurement results of the protective layer. From this figure, many organic polymer compounds were present on the surface of the protective layer on the photocatalyst layer side, and no component-graded structure could be confirmed.
- the substrate in this example had a large increase in the haze value in the solvent resistance test, and the durability of the photocatalyst was extremely poor. Comparative Example 3
- Example 1 The same operation as in Example 1 was performed, except that a layer of acrylic silicone resin [Nippon Soda Co., Ltd. “Vistrator NRC-30 OA”) was provided as a protective layer in Example 1. Table 1 shows the evaluation results.
- PET polyethylene terephthalate
- TORENE clay “Lumilar T-60” an ultraviolet absorbing primer [Nippon Shokubai Kagaku Co., Ltd. "U Double UV-G300”] 100 g equivalent and isocyanate-based curing 15 g of an agent [Sumitomo Bayer Urethane Co., Ltd. “Sumidur N-320 °”] was mixed and applied with a thickness of 5 ⁇ to obtain a PET film with a weather-resistant layer.
- This film was subjected to an accelerated weathering test with a light source of 255 W / 1000 hours using a sunshine weather meter (hereinafter abbreviated as SWM), and the total light transmittance was 88%, the haze value was 2.0%, and the yellowing degree ( YI) 5.5, and the change in haze value in the solvent resistance test was 0, 1%.
- SWM sunshine weather meter
- Table 2 shows the evaluation results.
- a photocatalyst solution [“PC-455” manufactured by Titanium Industry Co., Ltd.] was applied on the composite gradient film to form a photocatalyst layer having a thickness of 40 nm.
- a 30 / im-thick protective film [Sanitek PAC 2-70 manufactured by San-A Kaken Co., Ltd.] is cold-laminated on the photocatalyst layer.
- PET adhesive film 100 parts by weight of adhesive “BP S_5296” manufactured by Toyo Ink Manufacturing Co., Ltd. and 30 parts by weight of curing agent “BXX_4773”] with a thickness of 25 Xm
- a release film with an adhesive was laminated to produce a photocatalyst film.
- Test pieces were prepared from the photocatalyst film prepared in (2) above in the following procedure.
- the photocatalyst film from which the release film was peeled off was placed on a 2 mm thick 5 Omm square slide glass so that the adhesive layer was in contact with the photocatalyst film, and then a rubber roller was used to press and adhere to the film. Then, the protective film was peeled off to obtain a sample for evaluation.
- This photocatalyst film sample had a total light transmittance of 87%, a haze value of 2.7%, a yellowing degree (YI) of 6, and a water contact angle of 5 ° after accelerated weathering with a light source of 255 W / m for 1000 hours using SWM.
- Table 2 shows the evaluation results. Table 2
- T T Total light transmittance
- H Z Haze value
- Y I Haze value
- various functional films having a photocatalytic active material layer on the surface of a base film via a protective layer, having excellent weather resistance, transparency and interlayer adhesion, and exhibiting a photocatalytic function are provided. It is possible to provide a photocatalytic film which is useful for applications and has a particularly long life, and a structure provided with the photocatalytic film and having a photocatalytic ability on the surface thereof.
