Abstract: A molded article having an adhesion of at least 50 squares per 100 squares in crosscut adhesion test and at least 40 squares per 100 squares even after kept in a warm water of 70.degree. C. for 1 hour, a haze value of 1.0% or less in Taber abrasion test and a pencil hardness of 2H or higher, said molded article being obtained by modifying the surface of a substrate formed of a thermoplastic norbornene resin to have a surface tension of 50 dynes/cm or greater by a treatment such as corona discharge treatment or the like or forming a preliminary primer layer of a modified product obtained by introducing a polar group into a copolymer of a vinyl aromatic compound and a conjugated diene, or the like; forming a primer layer for silicone hard coating agent on the modified surface or the preliminary primer layer, and then forming thereon a silicone hard coat layer, and a method for producing the molded article.
