染等の問題を解消することができるものである。That is, the adhesive of the present invention n<P that crosslinks only upon radiation
By forming a VC blended composition layer, it can be processed in an uncured state before irradiation, and after processing, it can be irradiated with radiation to increase the surface hardness, making it less prone to scratches and wear than conventional products. This can solve problems such as poor performance and contamination due to leaching of liquid over time.
