The present invention provides a method for laminating a decorative metal film on a resin base material with excellent adhesion to the resin base material and with a sufficient gloss imparted to the decorative metal film, and a resin base material having a decorative metal film. The method laminates a polymeric planarizing film on the resin base material using a vapor deposition polymerization method, and then laminates the decorative metal film on the planarizing film.

Method for lamination of decorative metal film on resin base material, and resin base material having decorative metal film thereon

An object of the present invention is to provide an apparatus and a method by which quantities of water vapor passing through a measured object can be measured with high sensitivity and in a short time period. The apparatus and method measure water vapor permeability of the measured object based on a dew point temperature in a second space measured after introducing water vapor into a first space, wherein the first space and the second space are parted from each other by the measured object, and wherein the first space is maintained at a predetermined temperature and a predetermined humidity under atmospheric pressure, and the second space is maintained in a dry state with a dew point temperature of &#x2212;70&#xb0; C. or less under atmospheric pressure.
