Benzophenone UV absorbers such as benzoylphenyl) methane; azomethine UV absorbers; indole UV absorbers; and triazine UV absorbers.
Among these ultraviolet absorbers, a benzotriazole-based ultraviolet absorber is preferable because it has the best ultraviolet absorbing ability. Further, these ultraviolet absorbers may be used alone or in combination of two or more. It should be noted that the UV absorber is classified into any of these UV absorbers according to the main skeleton of the chemical structural formula.

外観、経済性の点で問題が生じやすい。[0009] UV absorbers are appropriate to be added to the acrylic resin film in the range of 0.05~6g / m 2, it is preferably added in a range of 0.15~3g / m 2. If the amount of the ultraviolet absorber is less than 0.05 g / m 2, sufficient weather resistance cannot be obtained. When the amount of the ultraviolet absorber added exceeds 6 g / m 2 ,
Problems tend to occur in terms of appearance and economy.

しにくいため、３００μｍ以下であることが好ましい。The thickness of the acrylic resin film used in the present invention is not particularly limited as long as the concentration of the ultraviolet absorbent per unit area is within the above range, but if it exceeds 300 μm, the rigidity becomes too large to be used as a protective film. Since it is difficult to use, the thickness is preferably 300 μm or less.

（比較例５）。変色の評価基準は下記によった。Table 2 shows the results of measuring the ultraviolet absorption performance of the obtained film. Further, the obtained acrylic resin film was bonded to a vinyl chloride wallpaper using a heating roll, and the obtained wallpaper was irradiated with ultraviolet rays for 50 hours using an eye super UV tester (100 mW / c).
m 2 ) and the degree of discoloration was visually evaluated (Examples 1 to 3).
5, Comparative Examples 1-4). In addition, a vinyl chloride wallpaper to which an acrylic resin film was not attached was similarly evaluated (Comparative Example 5). The evaluation criteria for discoloration were as follows.
【００１９】 ○：変色ほとんど無し △：変色少しあり ×：かなりの変色が見られる：: almost no discoloration Δ: slight discoloration X: considerable discoloration is observed
