| abstract |
The present invention is a tent paper canvas coated with a photocatalyst, (1) the adhesion between the photocatalyst and the tent paper canvas is maintained for a long time, (2) the antifouling ability is maintained for a long time, (3) tent It is an object of the present invention to provide a tent paper canvas in which the photocatalyst supported on the paper canvas does not promote a decrease in tear strength over time.n n n The photocatalyst is coated on the surface of which the amount of plasticizer contained in the tent paper canvas remains at least 50% after 1500 hours of sunshine carbon arc accelerated weathering test specified in JIS-K5400 or after 3 years of outdoor exposure. The tent paper canvas is used, and the tent paper canvas having the above properties and structures further contains a plasticizer having a molecular weight of 400 or more, and / or a plasticizer migration suppression layer is provided between the tent paper and the photocatalyst coating layer. |
