PURPOSE:To improve the adhesive property between a substrate and a lens part by applying a specified compd. on the surface of a transparent resin base material, then irradiating the coating with active energy rays. CONSTITUTION:A UV curing type resin liquid is interposed between the transparent resin base material and a lens mold and is then irradiated it with UV rays to form the lens part on at least one surface of the transparent resin base material. The compd. expressed by formula I is previously applied on at least the surface of the transparent resin base material, which surface comes into contact with the UV curing type resin liquid. The coating is thereafter irradiated with the active rays. The adhesive property between the substrate and the lens part is improved in this way. In the formula, R1, R2 are H or CH3; n is 0 to 4 integer. |
