Abstract
The present invention is directed to an article comprising a thermoplastic polymer film and a discontinuous metallic nanoparticle coating, of an average size less than 100 nm, and the process for preparing the same. The coated film may be further stretched or shrunk to shift the absorbance peak maximum to the desired degree. The coating is formed by depositing a discontinuous layer of metallic nanoparticles by a physical vapor deposition method.
