Description

[Detailed Description of the Invention] The present invention relates to a plastic card, and more particularly to a plastic card with a pseudo-transparent pattern.

Traditional plastic cards are plain, and plastic cards with watermarks are no longer available.

The inventor of the present invention focused on the fact that a plastic card with a watermark pattern allows a watermark to be added to indicate a specific membership, or a watermark to prevent counterfeiting. As a result of research to obtain a patterned plastic card, we selected a material with lower opacity than that used to make conventional plastic cards as the material for making the center core, and we also used a material with a lower opacity than that used to make conventional plastic cards. We have discovered that it is possible to form a pseudo-watermarked center core by sandwiching an opaque printed film displaying a watermark pattern between the center core-constituting sheets, and based on this knowledge, we have developed the following: Two center core forming sheets made of milky white or bone white plastic sheets having an opacity sufficient to form a plastic card with an opacity of 1.00 or more and 2.00 or less in the base portion are overlapped with each other with a transparent pattern printed layer interposed therebetween. , a pseudo-watermarked plastic card comprising a center core which is bonded between layers and has a card information printing layer on one or both sides, and a transparent overlay layer covering the entire front and back surfaces of the center core. The present invention was completed with the gist of ``.''.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a pseudo-watermarked plastic card 6 according to the present invention.

Pseudo-watermarked plastic card 6 according to the present invention
The center core 3 is constructed by laminating two center core forming sheets 1a and 1b with an openwork print layer 2 interposed therebetween and bonding between the layers. A card information printing layer 4 is provided on one or both sides of the center core 3, and a transparent overlay layer 5 is further provided on both sides of the center core 3.
is provided.

In the pseudo-watermarked plastic card 6 according to the present invention, the center core forming sheet 1
As a and 1b, milky white or bone white plastic sheets made of polyvinyl chloride, polypropylene, acrylic resin, styrene resin, etc. can be used. Furthermore, if the opacity of the base part of the plastic card is 2.00 or higher (as in conventional plastic cards), the black transparency will be difficult to see.
On the other hand, if the opacity is less than 1.00, the black transparency will be too noticeable and there is a risk that it will be difficult to read the information displayed on the plastic card.
As the sheet for forming the center core, it is desirable to select and use a sheet whose base portion has an opacity of 1.00 or more and 2.00 or less, which is sufficient to form a plastic card.

Next, in the pseudo-watermarked plastic card 6 according to the present invention, the watermark printing layer 2 is coated with black ink and white on the inner surface of one of the two center core forming sheets 1a and 1b. It is possible to use a print formed by using a highly opaque ink such as opaque ink by a normal printing method such as a screen printing method, a gravure printing method, or an offset printing method.

As detailed above, the pseudo-watermarked plastic card according to the present invention has a center core structure in which two sheets for forming the center core are overlapped with a watermark printing layer interposed therebetween and bonded between the layers. Therefore, according to the present invention, a mark indicating that the member is a specified member is attached as a pseudo watermark.
It is possible to construct a plastic card that allows one to identify with a single glance whether or not the card belongs to a specific member. In addition, in such a case, the pseudo-watermarked plastic card will be noticed by people other than the card holder, so the pseudo-watermark mark etc. attached to the plastic card will also serve the function of advertising the card issuing company or issuing organization. be. In addition, according to the present invention, a counterfeit prevention mark specified by the card issuer based on the card issue period, issue area, etc. is attached as a pseudo watermark,
It is also possible to configure an anti-counterfeiting card.
