Abstract
A coated sheet for decorative or informational applications is formed of an oil absorbing substrate and an oil permeable decorative layer. The decorative layer is a porous oleophilic membrane formed from fused polymer particles. Skin oil and certain other liquids placed on the exposed surface of the decorative layer are absorbed into the sheet so that they do not appear on that surface and do not interfere with the optical effect of diffraction gratings or holograms thereon.
