Abstract: A technique is disclosed for transferring information from a hot stamping foil or other physical transfer elements to a substrate wherein the adhesive used to attach the information to the substrate is a solid, radiation-curable resin which is cured by radiation to form a tenaciously adhered bond between the substrate and the information transferred. The resulting bond is resistant to solvents, chemicals, detergents, heat and mechanical stresses likely to be encountered in the use of substrates.

Abstract: A method for making transparent, reflective films includes coating a polymer film with ZnS by charging a set of carbon crucibles with ZnS cubes or pellets. The crucibles are heated by induction in a vacuum deposition chamber having a supply roll of the polymer film and a take-up roll. The ZnS cubes sublimate at a rate matched to web advance to insure a coating thickness for colorless films of at least 1,000 angstroms. The thickness of the ZnS layer on the film is monitored by visual observation of color by a source of visible white light and the rate of transfer of the film is adjusted to control the thickness of the ZnS layer.

Abstract: A phase hologram is embossed in a mylar web having a reflective layer which is made from tin tungsten oxide, zinc sulfide, or a mixture thereof. The embossed microtexture produces a hologram that is semi-transparent, thereby allowing the visualization of indicia underlying the hologram.

Abstract: There is provided a novel substantially anhydrous UV curable composition comprising a monomer and a solvent wherein the monomer is a multi-functional, non-oxygen inhibited polyacrylate and the solvent is a low volatility solvent containing at least 2 oxygenated functions which is substantially incorporated into the polymer during the curing step. There is also provided a method of curing such compositions which avoids the conventional drying step required heretofore.

Abstract: A continuous process for preparing finely divided thin, bright metal particles which comprises applying a release coating to at least one side of a carrier sheet, depositing a metal film of from 350 to 450 angstroms thickness onto the release coating solubilizing the release coating, removing the metal film from the carrier sheet, and breaking the thin metal film into particles having a diameter of between 25 to 50 microns.
