Abstract
Abstract Films coated with a primer and an adhered layer of metal, metal oxide, metal salt, semiconductor material are shown. The primer is comprised of binder and powder particles and is coated to a dry thickness between 1 micron and 100 microns. The powder particles have a median effective spherical diameter between 0.5 microns and 100 microns.
