性が低下するという問題点があった。[Problems to be Solved by the Invention] However, in the above-mentioned molding, a molding made of a vinyl chloride resin is repeatedly contracted and expanded due to a temperature difference between daytime, nighttime, summer, and winter. Double-sided tape due to factors such as shrinkage due to volatilization, and the interaction of heat, light, moisture, etc., causes the plasticizer and stabilizer in the vinyl chloride resin to decompose and become low molecular weight, and to shrink due to volatilization of these in the air. There is a problem in that the adhesiveness between the molding and the body or the body is reduced.

えられる。The reason why the test pieces of each example show such excellent performance is that the (meth) acrylate having 4 to 18 carbon atoms that exhibits flexibility and tackiness and the polyfunctional acrylic compound that forms an appropriate crosslinked structure. Is copolymerized by UV irradiation, and it is believed that the resulting high-molecular-weight acrylic polymer exhibits sufficient cohesive strength of the adhesive layer and excellent adhesion at the interface between the adhesive layer and the vinyl chloride resin plate. To be In addition, by blending a foaming agent, the surface layer of the adhesive layer foams and the foamed portion also functions as the base material of the double-sided tape (previously a foam of chloroprene rubber). It is considered that the high molecular weight acrylic polymer having the adhesive property and applied to the resin plate suppresses the generation of sound.
