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:
an extruded polymeric primary film substrate having embossed images with holographic-style prismatic surfaces extruded therein from a master film having holographic-style prismatic images with a plurality of differing depth characteristics that reflect light at differing angles, the embossed images with prismatic surfaces are visible on a face of the extruded polymeric primary film and provide three-dimensional decorative characteristics to products to which the extruded primary film is applied;
said embossed images with prismatic surfaces of the extruded primary film substrate are holographic-style diffractive optical elements of image-imparting prismal etching and jagged etch cuts;
said extruded polymeric primary film is comprised of a polymer having a melt temperature of at least about 175° C.;
said extruded polymeric primary film is comprised of 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 (i) the embossed images and their prismatic surfaces that are holographic-style diffractive optical elements of image-imparting prismal etching and jagged etch cuts and (ii) the dye pattern are simultaneously visible at identical locations of the substrate.
2. 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.
3. 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.
4. The substrate according to claim 1 , further including 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.
5. The substrate according to claim 1 , wherein the embossed images with holographic-style prismatic surfaces comprise patterns of variable shifting spectral coloring.
6. A product intended for rugged use and having a decorative holographic-style surface, comprising:
a product intended for rugged use and including on an external portion thereof an extruded polymeric primary film substrate having embossed images with holographic-style prismatic surfaces extruded therein from a master film having holographic-style prismatic images with a plurality of differing depth characteristics that reflect light at differing angles, the embossed images with prismatic surfaces are visible on said external portion of the product and provide three-dimensional decorative characteristics to said product;
said embossed images with prismatic surfaces of the extruded primary film substrate are holographic-style diffractive optical elements of image-imparting primal etching and jagged etch cuts;
said extruded polymeric primary film is comprised of a polymer having a melt temperature of at least about 175° C.;
said extruded polymeric primary film is comprised of 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 (i) the embossed images and their prismatic surfaces that are holographic-style diffractive optical elements of image-imparting prismal etching and jagged etch cuts and (ii) the dye pattern are simultaneously visible at identical locations of the substrate.
7. The product according to claim 6 , wherein the product is a recreational sportsboard.
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, polybutylene terephthalate, polytrimethylene terephthalate, acrylics, nylons, polyurethanes, and combinations thereof.
9. The product according to claim 6 , further including a backing applied to the surface that is opposite to the face of the extruded polymeric primary film that has the embossed images, said backing being between the extruded polymeric primary film and the external portion of the product.
10. The product according to claim 6 , wherein the embossed images with holographic-style prismatic surfaces comprise patterns of variable shifting spectral coloring.
