Methods for enhancing the visibility of and imparting a metallic luster to holographic and diffraction pattern surface embossments on transparent media such as plastic films (12) are disclosed. Enhancement is achieved by (1), metallic effect dyes or (2), metal flake inks containing minimal quantities of resinous binders (3), inks containing crystalline pigments that have metallic visual effects, or (4), inks containing pigments formed of optical stacks. The solvent used during application of the dye or ink must not be a solvent for the embossed surface.

Method of enhancing the visibility of diffraction pattern surface

A decorative sheet 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. Fingerprints and other skin oil 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.

Method of forming a coated sheet which wicks away oil

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.

Method of forming a coated sheet which wicks away oil and product thereof

Coating sheet which wicks away oil

The invention comprises a toner receptive coating for substrates, typically paper, label or tag stock, for use in conventional printers such as ion deposition printers and photostatic copiers. The coating on paper or polymeric film improves the print density and durability of text or images transferred thereto from printers or copiers, particularly those which employ dry magnetic toner. The coating eliminates the need to use heat fusing to fix the transferred toned image to the substrate. The coating is composed of pressure sensitive polymeric binder material and particulate fillers. The polymeric binder has a glass transition temperature less than 20.degree. C. preferably a glass transition temperature between -10.degree. C. and +10.degree. C. The fillers include a polymeric filler, typically a polyethylene wax or a polyethylene/polytetrafluoroethylene wax mixture and a mineral filler, typically particulate silicon dioxide. The receptive coating also improves the smudge resistance of transferred toned images, particularly when employing dry magnetic toner. The coating can be used to fix (without heat fusing) the transferred toned image to paper, tag or label stock that has been coated with a pressure sensitive adhesive on the opposite side.
