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 method for manufacturing a holographic-style film for application to products to impart holographic-style decoration thereto, comprising:
providing a polymeric master film having images that are embossed to exhibit a plurality of differing depth characteristics that reflect light at differing angles;
extruding a molten primary film polymer onto the polymeric master film and onto its embossed images without distorting the master film and its embossed images;
allowing the molten polymer to cool into an extruded primary film, said extruded primary film polymer facilitating formation of image embossments on a face of the primary film to provide a combination film comprising the primary film with said image embossments and the polymeric master film joined together, the extruded primary film image embossments being an inverse image of the embossed images of the polymeric master film;
applying the combination film to a product;
separating the master film and the extruded polymeric primary film with its image embossments, the extruded primary film being a holographic-style film having an embossed face and that is suitable for application onto a product to be given holographic-style decoration, wherein said separating is carried out after the combination film is applied onto the product; and
sublimation dye treating the embossed face of the extruded polymeric primary film with a sublimation dye printing pattern thereby chemically absorbing the printing pattern into and below the surface of the image embossments of the polymeric primary film such that the printing pattern does not obscure the image embossments, whereby the printing pattern and image embossments are simultaneously visible at identical locations on the embossed face.
2. The method according to claim 1 , further including applying a backing to the extruded polymeric primary film at a location other than its said embossed face to provide a backed holographic-style laminate for application to a rugged-use product.
3. The method according to claim 1 , wherein the sublimation dye treating is gaseous phase diffusion dye printing, the printing pattern is a decorative pattern, further including applying a backing to a surface opposite of the embossed face to provide a backed holographic-style laminate of the combination file and backing, whereby the applying step applies the laminate to a rugged use product.
4. A method for manufacturing a recreational sportsboard having a holographic-style film on a surface thereof, comprising:
providing a polymeric master film having images that are embossed to exhibit a plurality of differing depth characteristics that reflect light at differing angles;
extruding a molten primary film polymer onto the polymeric master film and onto its embossed images without distorting the master film and its embossed images;
allowing the molten polymer to cool into a primary film to provide a combination film comprising the primary film and the master film joined together, said primary film polymer facilitating formation of image embossments on a face of the primary film, the primary film image embossments being an inverse image of the embossed images of the polymeric master film;
applying a backing to a surface opposite of the embossed face to provide a backed laminate for application to the sportsboard product and that simultaneously displays at identical locations the decorative pattern and the image embossments of the polymeric primary film;
applying the rugged holographic-style film backed laminate to the surface of a recreational sportsboard product;
separating the combination film into the master film and the extruded polymeric primary film with the image embossments, the primary film being a rugged holographic-style film;
gaseous phase diffusion dye treating of the embossed face of the polymeric primary film with a decorative pattern thereby chemically absorbing the decorative pattern into and below the surface of the image embossments of the polymeric primary film such that the decorative pattern does not obscure the image embossments whereby the decorative pattern and image embossments are simultaneously visible at identical locations on the embossed face; and
wherein said separating is carried out after the combined film is applied onto the sportsboard product.
