Low-cost tough decorative printable film products having holographic-type images
View Patent ↗Tough decorative printable film products having holographic-type images are provided that are low in cost. These film products include a relatively high temperature film that is made by continuous extrusion of the film resin onto a master film having pre-etched holographic-type imaging in order to provide a high-temperature primary film with conforming holographic imaging. This primary film provides a tough holographic-type image that is readily secured to any number of products to impart a holographic character to them. For example, this primary film is suitable for use on the surface of recreational sportsboards. When desired, sublimation printing can be used to impart indicia, text, images and colors, alone or in combination, to the primary film.
1. A decorative holographic-style substrate for a product intended for rugged use, comprising:
a substrate comprising an extruded polymeric primary film of a polymer having a melt temperature of at least about 175° C. and having embossed images extruded therein from a master film to form in the extruded polymeric primary film holographic-style prismatic images that are defractive optical elements of prismal etching and jagged etch cuts with a plurality of differing depth characteristics that reflect light at differing angles;
the substrate further comprising a backing applied to the surface of the substrate that is opposite to the face of the extruded polymeric primary film that has the embossed images, and the substrate is further comprised as a revealed substrate that has the master film removed from the primary polymeric primary film;
the backing of the revealed substrate is intended to be bonded to the external portion of a product component, whereby the embossed images with prismatic surfaces of the extruded polymeric primary film are visible on a face of the extruded polymeric primary film and provide three-dimensional decorative characteristics to product components to which the revealed substrate is applied;
said extruded polymeric primary film is a sublimation dye-receptive polymer that accepts dye sublimation printing; and
a sublimation dye pattern on the embossed images at the face of the extruded polymeric primary film that has the embossed images with prismatic surfaces, and wherein both (i) the embossed images, including their hololgraphic-style prismatic images and (ii) the dye pattern are simultaneously visible at identical locations of the substrate.
2. The substrate according to claim 1 , wherein the embossed images with holographic-style prismatic surfaces comprise patterns of variable shifting spectral coloring.
3. The substrate according to claim 1 , wherein the characteristics of the sublimation dye and of the embossed images are simultaneously visible at identical locations of the substrate.
4. The substrate according to claim 1 , wherein the polymer of the extruded polymeric primary film has a melt temperature of at least about 200° C.
5. The substrate according to claim 1 , wherein the polymer of the extruded polymeric primary film is a thermoplastic polymer selected from the group consisting of a polyester, polybutylene terephthalate, polytrimethylene terephthalate, acrylics, nylons, polyurethanes, and combinations thereof.
6. A product intended for rugged use and having a decorative holographic-style surface, comprising:
a product component intended for rugged use and including an external portion thereof;
a substrate comprising an extruded polymeric primary film of a polymer having a melt temperature of at least about 175° C. and having embossed images extruded therein from a master film to form in the extruded polymeric primary film holographic-style prismatic images that are diffractive optical elements of prismal etching and jagged etch cuts with a plurality of differing depth characteristics that reflect light at differing angles;
the substrate further comprising a backing applied to the surface of the substrate that is opposite to the face of the extruded polymeric primary film that has the embossed images, and the substrate is further comprised as a revealed substrate that has the master film removed from the primary polymeric primary film;
the backing of the revealed substrate is bonded to the external portion of the product component, whereby the embossed images with prismatic surfaces of the extruded polymeric primary film are visible on said external portion of the product and provide three-dimensional decorative characteristics to said product component;
said extruded polymeric primary film is a sublimation dye-receptive polymer that accepts dye sublimation printing; and
a sublimation dye pattern on the embossed images at the face of the extruded polymeric primary film that has the embossed images with prismatic surfaces, and wherein both (i) the embossed images, including their holographic-style prismatic images and (ii) the dye pattern are simultaneously visible at identical locations of the substrate.
7. The product according to claim 6 , wherein the polymer of the extruded polymeric primary film has a melt temperature of at least about 200° C.
8. The product according to claim 6 , wherein the polymer of the extruded polymeric primary film is a thermoplastic polymer selected from the group consisting of a polyester, polystyrene, high melting point polyolefin, polyethyl vinylacetate copolymer, polyethyl ethyl acrylate copolymer, polyethyl methyl acrylate, polybutylene terephthalate, polytrimethylene terephthalate, acrylics, nylons, polyurethanes, and combinations thereof.
9. The product according to claim 6 , wherein the polymer of the extruded polymeric primary film is a thermoplastic polymer selected from the group consisting of a polyester, polybutylene terephthalate, polytrimethylene terephthalate, acrylics, nylons, polyurethanes, and combinations thereof.
10. The product according to claim 6 , wherein the characteristics of the sublimation dye and of the embossed images are simultaneously visible at identical locations of the substrate.
11. The substrate according to claim 6 , wherein the face of the extruded polymeric primary film having embossed images is gaseous phase diffusion dye printed with a decorative pattern.
12. The substrate according to claim 6 , wherein said polymeric master film is holographic sheeting previously having a metallized top layer and from which the metallized top layer had been removed to leave said pre-etched polymeric master film.
