The material is not particularly limited, and may be either a thermoplastic resin or a thermosetting resin as long as it has good adhesion to the transparent substrate. In particular, in order to easily carry out the adhesive treatment, thermoplastic resins are suitable, such as polyamide resins, polyester resins, ethyl cellulose, ethylene-vinyl acetate copolymers, vinyl acetate resins or derivatives thereof, polystyrene or copolymers thereof, and butyl resins. Examples include acrylic rubber made of methacrylic resin or a copolymer thereof, polyisobutylene, polypropylene, and the like.
