SOLUTION: At least on a face at one side, a face which accepts an image 15 and a data 17 is provided. An identification data contains images and characters or numerals. On each face of a core, a non-oriented polyester film having an adhesive layer is formed. On one face or both faces of the film, a hard coat is provided. Abrasion resistance and copy resistance are given to a completed card.

Description

Detailed Description of the Invention

A security card, which is a term that includes an identification card, a driver's license, and a financial transaction card such as a credit card, a loan card, and a card for an automatic teller machine, is usually a person's identification data or a photo You have both on one or both sides of the card. When using, pass the warranty card through the "reader". The reader reads the magnetic stripe, bar code or optical characters on one or both sides of the card. The warranty card must not curl for it to be read correctly. The interaction of the security card with the reader often results in scratches on the surface of the card, which can eventually lead to reader misreading of the data on the security card.

Prior art security cards use a film of oriented polyester as the outer wear surface to provide scratch resistance, which film protects the core containing the photographic image and / or data. . However, when an oriented polyester film is used for a guarantee card, the card often curls during the laminating process due to relaxation of the stretched polyester of the card or orientation disorder. Cards that are not flat can cause problems in use, as they may not be able to be read accurately by the machine. Some warranty card manufacturers avoid the problem of curling cards by using non-oriented polyester film for the outer wear surface of the laminated construction security cards. However, security cards with a non-oriented polyester outer surface tend to copy traces of the surface that the card contacts when heated during the laminating process. Examples of traces that are picked up on the face of such cards are traces of lamination rollers or carriers that are often used to convey components of the warranty card during the laminating process. The collection of such unwanted marks on the face of the card usually means “replication (re
replication) ”.

Therefore, a primary object of the present invention is to provide a non-curl, scratch and replication resistant security card that can be laminated with layers of non-oriented polyester film.

Another object of the present invention is to provide a laminated security card having a scratch and replication resistant coating applied to at least one non-oriented polyester film which is the exterior surface of the card. That is.

Yet another object of the present invention is to provide a laminated security card in which a scratch and replication resistant coating is applied to both outer surfaces of the card.

Other objects of the present invention will be apparent from the following detailed description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a component development view of an embodiment of a guarantee card of the present invention. The warranty card 11 of this embodiment includes a core 13. This core may be a sheet of photographic printing paper or a sheet of resin substrate having an image receiving surface formed on one or both sides thereof. The image receiving surface may be a separate photographic printing paper, or it may be a photographic emulsion to which the identification data image can be applied by photography.
Further, the one or more image-receiving layers of the core 13 are image 1 produced by a multicolor laser printer, an inkjet printer or a diffusion dye printer.
5 and data 17 can also be configured to be received. In other words, the image 15 may be a photographic image or, alternatively, a computer created image. This image and / or data can be formed on one or both sides of core 13.

In the completed card 11, adhesive films 19 are arranged on both sides of the core 13, respectively. This adhesive film is a heat-sensitive adhesive film characteristically compatible with a non-oriented polyester film. A layer of non-oriented polyester 21 is disposed on each outer surface of each adhesive film 19. Image 15
A hard coat 23 is provided on the outer surface of the non-oriented polyester film 21 on the core 13 side having the data 17 and the data 17. Various paints are available for use as this hard coat 23, and such paints can be cured by UV or electron beams in an air atmosphere or an oxygen atmosphere. Many of these hardcoats show good adhesion to polyester fills. GA is an example of a suitable hard coat
It is available on the market under the trade name of FGARD 233, which is an Abrasion Resistant Radiation Curable.
It is called Coating.

To facilitate manufacture and assembly, an adhesive film 19 is applied to one side of a non-oriented polyester film 21 and the laminate of adhesive film and polyester film is in the form of a separate die cut panel or elongated roll. Will be supplied to the final assembly machine. Then another laminate containing a non-oriented polyester film 21 with an adhesive film 19 applied on one side and a hard coat 23 on the other side is fed to a guarantee card assembly machine of the same shape as above. . And these 2
Two laminates, one with layers 19 and 21 and the other with layers 19, 21 and 23, are laminated by a conventional lamination process involving heating rollers to form a complete warranty card 11. be able to.

A second embodiment of the scratch and copy resistant polyester security card of the present invention is shown in FIG. In the case of this embodiment, the warranty card 31 comprises a core 33 similar to the core 13 of the previous embodiment, this core 33
Can also have image 35 and data 37 on one or both sides. Adhesive film layers 39 similar to the adhesive film layer 19 are arranged on both sides of the core 33. A non-oriented polyester film 41 is arranged on the outer surface of each of the adhesive films 39, and a hard coat 43 similar to the hard coat 23 described above is laminated on the outer surface of each non-oriented polyester film 41.
The hard coat 43 is cured by the same method as described above. Two laminates, each having three layers 39, 41, 43, are laminated to the core 33 in a conventional manner using heated rollers to complete the complete warranty card 31. The guarantee card 31 has hard coats 43 on both surfaces thereof, which prevents scratches on the card during use and also eliminates the tendency to copy traces of the surface contacted by the card during the lamination process.
