Abstract
An object of the invention is to provide a laminate which is good in adhesiveness between a substrate and a thin film laminated thereon by a dry film-forming method such as a chemical vapor growth method or a vacuum evaporation method even if the substrate is a polymer substrate made of a nonpolar polymer; and a process for producing the same. In order to attain the above-mentioned object, the invention provides a laminate comprising a polymer substrate, a primer layer comprising a cyclized rubber which is a conjugated diene polymer cyclized product or a derivative thereof, the layer being formed on the surface of the polymer substrate, and a thin film laminated on the surface of the primer layer by a dry film-forming method; and a process for producing the same.
