Acrylic pressure-sensitive adhesive on the side to be attached to glass is 10 to 20 μm
On the other side of the coating, for example, one coated with a hard coat agent such as a UV resin or the like having a thickness of 3 to 5 μm for the purpose of protecting the film from being damaged by a rubber spatula used when affixing the film to glass. It has been found that the scattering prevention performance of glass depends on the adhesive strength of the adhesive used to the glass surface, but if the adhesive strength is too high, the removability will be low, and the adhesive at the time of re-pasting will be reduced. There is a drawback that the remainder increases, so it is necessary to select an appropriate adhesive.
