Abstract
A light refractive coated paperboard is provided comprising a normally oil and grease permeable substrate, a non-leafing silver-colored ink layer applied to one surface of said substrate and a highly pigmented (titanium dioxide) ink layer superimposed on said non-leafing silver colored ink layer and possibly a clear lacquer or varnish layer superimposed on the TiO.sub.2 containing ink layer. The above order of coating layers produces a somewhat flat appearance; for producing a more metallic look the order of the silver-colored ink layer and of the highly pigmented (TiO.sub.2) layer are reversed. The light refractive coated paperboard conceals, from the outer surface of a package made therefrom, oil and grease stains which have penetrated the inner surface of the package. A method of making such light refractive coated paperboard is also disclosed.
