Moisture and abrasion resistant holographic products
First Claim
1. A holographic product suitable for attachment to a substrate comprising a transparent plastic top layer, a moisture impermeable adhesive bottom layer, an intermediate mirror-like layer of a metallic material which engages the said top layer to form an embossed surface capable of reflecting the holographic image or a diffraction grating pattern through the said top layer in the presence of light, and a seal along the entire perimeter of the assembly of said layers that binds the said layers together at the outside edges of the said layers making up the same assembly and thereby substantially prevents separation of the said three layers by either ordinary wear and tear or penetration by moisture.

Abstract
A product and process comprising a layered hologram and diffraction grating which will resist deterioration from abrasion and moisture as a separate article of commerce or when attached to a substrate (especially fabrics). Such resistance is accomplished by sealing the edges of the layered product and thereby protecting the embossed surface that produces the hologram image or the iridescent diffraction grating pattern. When attached to a substrate by a moisture impermeable adhesive, detachment from the substrate is also inhibited. The combination of holographic art with a printed graphic is thereby perfected.

- 6. In a process for producing embossed iron-on holographic films suitable for attachment to a substrate the improvement which comprises sealing the edges along the perimeter of the holographic film sufficiently to substantially inhibit penetration by moisture between the layers of the holographic film.
- 8. A process of interfacing a display hologram or a diffraction grating with printing for creating a total graphic, comprising in sequence, printing a graphic upon a fabric substrate with an adhesive silk screen printing ink, drying said printing ink, loading said substrate onto a lower platen of a thermostatically controlled heat transfer machine, inserting a heat radiating metal plate between said lower platen and an underside of said substrate against the rear side of a portion of the printed graphic of said substrate, said plate being of a contoured shape and of sufficient size to underlay the film that is to be placed upon a portion of said printed graphic, placing a film having the hologram or diffraction grating thereon on said printed graphic in registry with said metal plate with said ink underlying the entire area of said film, placing a glossy coated release paper on said film and on the remaining portion of said printing ink not covered by said film, said paper holding said film flat and preventing it from shifting, lowering an upper-heated element of said heat transfer machine onto said paper with sufficient heat and pressure to melt and soften said ink, said upper element radiating heat therefrom to said metal plate, said heat being reflected to a rear side of said ink while the top side of said ink is heated by said upper element, said heat being retained for a period of time, removing said upper heating element and said glossy paper and recovering said substrate including said graphic having said ink oozed upwardly around the edges of said film whereby said film is embedded in said ink to provide a strong bond while leaving a smooth, satin-finished surface on said film and ink.
- 13. An interfaced assembly having a fabric substrate, an embossed hologram having a holographic or a diffraction grating image thereon, and a plastisol adhesive underlying the entire area of said film in contact with said substrate and also encasing the perimeter of said film to provide a seal behind and at said perimeter of said film whereby repeated immersion of said assembly in water will not result in separation of said film from said substrate.
- 17. An interfaced assembly comprising a fabric substrate having a printed design thereon, a film having a holographic or a diffraction grating image thereon, and an adhesive silk screen printing ink underlying the entire area of said film in contact with sizing on the underside of said film whereby the printed design on said substrate cooperates with the image on said film to provide a total graphic and the adhesive ink and sizing together curl around and embed the edges of said film so as to prevent said film from peeling off or becoming detached during use and laundering.
-
21. An interfaced assembly comprising a fabric substrate having a printed design thereon, a film having a holographic or diffraction grating image thereon designed to overlay and cooperate with a portion of said printed design to provide a total graphic, an adhesive silk screen printing ink durable in the presence of wear and laundering overlying the entire area of said substrate overlaid by said film, said adhesive bonding together said fabric substrate and said film with said adhesive curling around and embedding the edges of said film so as to prevent said film from peeling off or becoming detached during use or repeated laundering.
-
22. An interfaced assembly having
a non-textile substrate selected from the group consisting of metal, wood, plastic, ceramic, leather, Masonite, glass, and paper, a film having a holographic or a diffraction grating image thereon, and a plastisol adhesive underlying the entire area of said film in contact with said substrate and also encasing the perimeter of said film to provide a seal behind and at said perimeter of aid film whereby repeated immersion of said assembly in water will not result in separation of said film from said substrate.
-
23. An interfaced assembly comprising
a substrate selected from the group consisting of metal, wood, plastic, ceramic, leather, Masonite, glass, and paper, a film having a holographic or a diffraction grating image thereon, and an adhesive silk screen printing ink underlying the entire area of said film in contact with sizing on the underside of said film whereby the printed design on said substrate cooperates with the image on said film to provide a total graphic and the adhesive ink and sizing together curl around and embed the edges of said film so as to prevent said film from peeling off or becoming detached during use.
