Abstract

Composite cards formed in accordance with the invention include a security layer comprising a hologram or diffraction grating formed at, or in, the center, or core layer, of the card. The hologram may be formed by embossing a designated area of the core layer with a diffraction pattern and depositing a thin layer of metal on the embossed layer. Additional layers may be selectively and symmetrically attached to the top and bottom surfaces of the core layer. A laser may be used to remove selected portions of the metal formed on the embossed layer, at selected stages of forming the card, to impart a selected pattern or information to the holographic region. The cards may be “lasered” when the cards being processed are attached to, and part of, a large sheet of material, whereby the “lasering” of all the cards on the sheet can be done at the same time and relatively inexpensively. Alternatively, each card may be individually “lasered” to produce desired alpha numeric information, bar codes information or a graphic image, after the sheets are die-cut into cards.

First claim

What is claimed is:

1. An assembly for forming a document comprising:
a clear plastic core layer having first and second, spaced apart, surfaces, extending generally parallel to each other;
a pattern embossed on, or in, said first surface of the clear plastic core layer;
a metal or a metal compound vapor deposited on the embossed pattern to form an embossed metalized pattern whereby light incident on the embossed metalized pattern produces a reflected light pattern corresponding to the embossed metalized pattern and wherein the vapor deposited metal, or metal compound, forms a layer which is thin enough to allow see-through; and
a selected number N of clear plastic layers formed on top of the embossed metalized pattern and a like number N of clear plastic buffer layers formed below the second surface of the clear plastic core layer; where N is an integer equal to, or greater than, one; said selected layers for forming a document having an embossed metalized pattern located along said first surface of the clear plastic core layer so as to be centrally located relative to a direction perpendicular to said first and second surfaces of the clear plastic core layer and protected and also for inhibiting the unauthorized alteration of the embossed metalized pattern while enabling the embossed metalized pattern to be visible wherein the embossed metalized pattern is a customized pattern and wherein said selected number of clear plastic layers includes a first clear plastic buffer layer attached to the top surface of the embossed metalized pattern via a first clear adhesive layer; where the top surface of the embossed metalized pattern is defined as the portion of the embossed metalized pattern away from the first surface of the clear plastic core layer; and a corresponding second clear plastic buffer layer attached to the second surface of the clear plastic core layer via a second clear adhesive layer; wherein the first and second clear plastic buffer layers have a predetermined thickness and wherein the first and second clear plastic buffer layers are of similar predetermined thickness; and wherein the first and second clear adhesive layers each have a certain thickness and wherein the first and second clear adhesive layers are of approximately the same certain thickness; and
a third clear plastic layer on which information may be selectively written attached to the first clear plastic layer and a fourth clear plastic layer on which information may be selectively written attached to the second clear plastic layer
and wherein selected ones of said additional layers include selected information; and wherein a window is formed within the pattern to enable the selected information to be seen.
