Molded articles having hard coat layer and method for producing same
First Claim
1. A molded article comprising a substrate formed of a thermoplastic norbornene resin having no polar groups, in which the surface of said substrate has been modified to produce a modified surface layer having a surface tension of at least 50 dynes/cm;
- a primer layer formed on the modified surface layer; and
a silicone hard coat layer formed on said primer layer as a top coat layer.

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° 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.
