Abstract

The present invention provides articles comprising a substrate, a coating that is applied to the substrate, and surface reliefs that are cast or embossed onto the coating at substantially the same speeds and widths of conventional printing, and in substantially perfect register to conventional printing, wherein the coating is selected from the group consisting of HRISR coatings, LRISR coatings, water-based coatings, solvent-based coatings, UV/EB based coatings, sol-gel based coatings, conductive coatings, silver reduction based coatings and metallic coatings, A protective or printed layer may (or may not) be applied on top of the coating. Specifically, if the coating is an HRISR or LRISR coating, then it is unnecessary to apply a special high refractive layer because HRISR and LRISR coatings inherently contain the refractive index properties that are necessary to keep the surface reliefs viewable despite any printing on top of the coating. Otherwise, if the coating does not comprise an HRISR or LRISR coating, then a high refractive protective layer is applied on top of the coating, wherein the protective layer follows a topography of the surface reliefs such that a thickness of the protective coating is substantially uniform.

Abstract

The present invention provides articles comprising a substrate (80), a high (or low) refractive index and/or metallic surface relief coating (84) that is applied to the substrate (80) and surface relief structures (86) that are applied to the coating (84) at substantially the same speeds and widths of conventional printing systems, and in substantially perfect register to conventional printing systems, thereby obviating the need for already-embossed substrates including films and hot-stamping foils.
