This material is plastic, iron , Plywood or the like can be used. As the base material, the door of the temporary enclosure entrance / exit Panels are preferred.

[0010]   In the present invention, as the transparent film, biaxially stretched polyester film, especially 2 Axial stretched polyethylene terephthalate film has weather resistance, transparency, flatness and surface light It is preferably used from the standpoints of temperature and mechanical properties. This biaxially stretched film has 25 It is preferable to have a thickness of ~ 200 μm, and dry heat freezing at 105 ° C. for 30 minutes. -The heat shrinkage in the vertical direction (longitudinal direction) is 4 to 14%, and the lateral direction (width direction) is 7-1. Those in the range of 7% are preferable. If it has such a heat shrinkage rate, it can be bonded to a substrate. It is possible to prevent sagging, wrinkles, etc. of the film after It Biaxially stretched polyethylene terephthalate film itself has good weather resistance. Although it is preferable, if it has the above-mentioned heat shrinkage ratio, this weather resistance becomes more excellent. Become. To improve the weather resistance, usually a means of incorporating an ultraviolet absorber into the film is used. However, by combining this measure with the above heat shrinkage properties, the weather resistance is further improved. can do. From this point, the wavelength of ultraviolet light is 380 nm (nanometer). UV absorbing weather resistant biaxially stretched polyethylene terephthalate that absorbs 85% or more of Use of a touch film prevents deterioration over time and improves transparency, flatness, surface gloss, etc. for a long period of time. The advantage is that it can be held for a while.

[0011]   In the present invention, it is necessary to print on one side of the transparent film described above. In order to improve the adhesion of printing ink, for example, easy adhesion primer treatment, corona treatment Etc. are preferably applied to the film surface. Examples of the primer treatment include poly A coating liquid containing an easy adhesive such as an ester easy adhesive, a polyurethane easy adhesive, and a mixture of the two. Is preferably applied to one side of the film in a thickness of 1 μm or less.
