DETAILED DESCRIPTION OF THE INVENTION
[0031]
[0032] The laser reactive film 104 is attached to the topside of metal layer 100, as shown as in
[0033] A laser reactive copolymer layer may be attached to the top and/or to the bottom of subassembly 50.
[0034] The introduction of the laser reactive copolymer layer 106b provides significant features. The laser reactive copolymer layer 106b is preferably an amorphous thermoplastic polyester plastic material such as polyethylene terephthalate (APET) or any like material. A significant aspect of this amorphous thermoplastic material is that certain of its properties change drastically as it is heated above its glass transition temperature, Tg, and below its melting point temperature, Tm. When heat is applied to the plastic material such that it is at a selected temperature, which exceeds its Tg and is less than its Tm, the plastic material starts to cross link or crystalize and enters a thermosetting state (rather than being a thermoplast). As used herein and in the appended claims, this means that its external shape cannot be changed without irreversible destruction from the form it assumed when it reached the selected temperature. Thus, the copolymer layer 106b can be heated to a selected temperature within this temperature range (between Tg and Tm) to cause the material to enter a crystalline state and assume a (thermo)set condition.
[0035] The temperature dependent characteristic of the copolymer layer 106b ensures that when the layer 106b is embossed (or debossed) with a pattern at a predetermined temperature (above the glass transition temperature, Tg, of the copolymer and below its melting temperature, Tm) it becomes thermoset, rather than being thermoplastic, and its external shape (the embossed form) cannot be changed from the embossed form to which it was set at the predetermined temperature without destroying the embossed pattern. The resultant embossed pattern is found to be scratch resistant and to mask scratches due to optical light reflectivity of the embossed pattern. The copolymer (e.g., APET) selected for use in practicing the invention is stiffer than PVC and can be thermally set into the desired pattern. By way of example, a co-polyester manufactured by Eastman Chemical under the brand name Tritan was used to make some experimental cards.
[0036] Another significant aspect of layer 106b is that it is also laser reactive so it can be laser engraved to enable information to be introduced on or within the layer. In addition, the laser reactive property enables the color of the layer to be altered to shades of black or white dependent on laser settings. The laser reactive portion of the copolymer layer enables virtually any desired information or design to be laser engraved on or within the layer and to also alter the color of the layer.
[0037]
[0038] Another significant aspect of the invention is that the embossed pattern alters the surface and body of layer 106b without substantially affecting the adjacent layers (e.g., layer 96 shown below layer 106b in
[0039] A significant benefit and result of the invention is that the embossed pattern formed on and within layer 106b is scratch resistant due to the hardness (firmness) of the pattern formed in the layer. In addition, any scratching of the surface is masked minimized. The material itself conforms to a more scratch resistant geometry and material state, and additionally draws the eye away from any scratches. The reflectivity of light incident on the surface (see

[0044] During card construction, the core layer 100 (e.g., metal substrate) may be treated with a laser, as shown in
[0045]
[0046] (a) Copolymer layers (106a, 106b) - - - 0.0015;
[0047] (b) Laser Reactive Film layer (104) - - - 0.002;
[0048] (c) Adhesive layer (102) - - - 0.0018;
[0049] (d) core layer(100) - - - 0155;
[0050] (e) Adhesive layer (98) - - - 0.0018; and
[0051] (f) Thermoplastic Layer (96) - - - 0.0070.
[0052] Note: The dimensions are illustrative only and the thickness of the various layers may be varied considerably in other cards embodying the invention.
[0053] Novel features of this invention include creating a transactional card with a physically embossed surface, the creation of such a surface using a lamination process which emulates a traditional gravure process, and the specific advantages of the embossing layer are described below.
[0054] The embossed layer provides several advantages over previous hybrid cards. [0055] a Raised physical nature of the layer provides desirable tactile and visual aspects to the card. [0056] b. The embossed layer can be composed of a co-polymer & other scratch resistant plastic. [0057] c. Provides larger range of colors than traditional metal coatings on metal cards by using a colored polymeric film layer. [0058] d. Provides controllable translucency to color on metal layer. [0059] e. Laser reactive front & back. [0060] f. Unique laser reactive layer that turns black or white depending on layer composition and laser operation. [0061] g. May contain metal or metal filled plastic
[0062] Processes for forming cards embodying the invention are shown in
[0067] Similarly, the layers shown in
[0068] The processing of the cards and their lamination and embossing can be accomplished by assembling all the components into one assembly and then laminating and embossing that assembly.
[0069] Alternatively, as indicated in
[0070] Utilization of a plastic embossed layer, rather than an etched or milled, metal embossed layer has an advantage when using a laser artwork or personalization technique. When applying a laser to a patterned metal surface, non-uniform coloring often occurs in raster like pattern due to the beam skipping across the patterned surface. With an identical, plastic, embossed pattern, the beam can penetrate the 3D structure of the embossed material, which creates a uniform color line without optical raster.
[0071] This artwork complements and is complemented by the embossed, laser reactive copolymer on the outside of these layers. In addition to artwork, the layers may be treated with the laser to provide personalization information such as account number, expiration, or account holder name in black, white, or any suitable color.
[0072]
[0073] Embossing the laser reactive copolymer layer also provides the ability to include security features that prevent counterfeiting. Examples include forming an embossing plate 601 with an optical lens 611 for embossing (or debossing) into the laser reactive copolymer 16 as shown in
