Description

Tape-type card products having improved security, and method for producing the same}

The present invention relates to a tape type security card with improved security and a method of manufacturing the same, and more particularly, a tape type security card and a method for manufacturing the same, which further improve security by attaching a scratch tape having excellent light shielding properties to a card stack. It is about.

Recently, you can see the cyber lottery, prepaid card, world phone card for making international calls, gift certificates, etc. Release.

There are various methods of this commercial security method, for example, the production of a tape type security method by printing silk on a tape, PET 50 micro polyester fabric on Fuji (automatic label) turquoise or white crashed paper It is prepared by laminating the adhesive with a silk ink on top of the silver ink, the conventional scratch tape products produced by the silk printing to directly cover the ink thick, there is a burden of excessive use of the printing ink and the resulting labor costs.

In addition, this method has a need for improvement because the area to be secured may be read by others because the light blocking ability is somewhat weak, and the printing surface is not smoothed by silk printing and is easily scratched during transportation and storage. .

Thus, in order to solve the above problems, the present applicant has a structure in which a base layer, a UV coating layer, a light shielding layer, and an aqueous coating layer are sequentially stacked, and the light shielding property of sequentially stacking a printing ink layer by a pressure printing method as a light shielding layer is applied. The improved scratch tape was filed in Korean Patent Application No. 2001-0013429 (filed March 15, 2001).

That is, when the light shielding layer is formed through pressure-sensitive printing on the tape, the part to be secured by completely blocking the light cannot be read by others, and the surface of the printing can be water-coated to prevent scratches during transportation and storage.

Such a scratch tape is directly attached to the card substrate after peeling off the substrate layer. The user did not know the card number or pattern before the user purchased directly, but the seller or manufacturer carefully peeled off the scratch tape from the card substrate. After confirming the numbers and patterns, there was a risk of deliberately fraudulent use and selling to consumers.

In addition, if it is based on credit, such as cyber lottery cards, such fraud may lead to credit crimes, and thus security needs to be further strengthened.

Accordingly, the present inventors earnestly researched to prevent fraudulent use of the security card by the seller or the manufacturer or credit crimes caused by the seller, and as a result, the UV coating layer and the shading on the card substrate were used to enhance the security of the scratch tape having excellent light shielding properties. After providing a layer and attaching it to the scratch tape, a tape type security card was developed in which a portion having a unique number or a pattern printed on the scratch tape was attached to the scratch tape so that it could not be seen even if light was emitted for use of the product. Reached. Therefore, as a complementary invention to the aforementioned Korean Patent Application No. 2001-0013429, the product is further enhanced in security.

Accordingly, an object of the present invention is to improve the security of the tape-type security that can be kept secret from the seller or manufacturer by attaching the card stack provided for security to the scratch tape and the card substrate with the shading layer formed on the tape through the pressure printing To provide the card.

Still another object of the present invention is to provide a method of manufacturing a tape type security card with improved security.

In the tape type security card 1 of the present invention, the adhesive layer 12, the fabric layer 13, the first UV coating layer 20, the first light shielding layer 30 and the water-based coating layer 40, the scratch is sequentially stacked The tape 2 has a structure attached to the card stack 3 in which the second UV coating layer 60 and the second light shielding layer 70 are sequentially stacked on the card substrate 50.

Hereinafter, the present invention will be described with reference to the drawings.

1 is a cross-sectional view showing a facing state of a scratch tape 2 and a card stack 3 for manufacturing a tape type security card 1 according to the present invention, and FIG. 2 is a tape type security card according to the present invention. It is sectional drawing which shows the laminated structure of (1).

The base layer 10 is composed of a paper layer 11, an adhesive layer 12 and a fabric layer 13, characterized in that the paper layer 11 is laminated with the fabric layer 13 with an adhesive on its surface. It is done.

In the present invention, as the paper layer 11, Fuji (automatic label) turquoise or white crashing paper is used, and as the adhesive for lamination, a conventional adhesive such as a polyurethane-based or synthetic rubber-based adhesive is diluted as it is or in a solvent. use. At this time, the adhesive force to the paper layer 11 is sufficient if it is laminated enough to be peeled off even with a slight force when attached to the card stack (3).

As the fabric layer 13, a polyester fabric such as PET 50 micro polyester fabric is used to improve the tear resistance of the scratch tape. At this time, the adhesive 12 is larger than the paper layer 11 and the adhesive force with the fabric layer 13 is left in the fabric layer 13 when peeling.

The first UV coating layer 20 is formed on the thus prepared substrate layer 10. The first UV coating layer 20 is applied by applying a UV paint, and then cured by irradiating with light. The UV coating layer 20 is coated with a conventional UV coating liquid.

The reason for the UV coating is to form a boundary layer that separates the base layer 10 and the first light shielding layer 30 so that the product is easily scratched after purchase, and printing by printing ink when the first light shielding layer 30 is formed. This is to improve the printability.

The first light shielding layer 30 is formed on the first UV coating layer 20 by sequentially printing with silver, white and dark color ink by a pressure printing method.

Printing ink is a viscous fluid and uses a product having excellent light blocking property in which light transmission is blocked by inorganic pigments contained in the printing ink.

The silver ink used to form the first light shielding layer 30 in the present invention is K2311049 of Korea Special Ink Co., Ltd., K2106235 of Korea Special Ink Co., Ltd., K2106235 of Korea Special Ink Co., Ltd. K2401096 is used, and flexel pressure printing press Zeller is used for pressure printing.

In the present specification, "flat pressure printing" refers to a format in which a plate is placed on a plate and covered with ink, a printed object is placed thereon, and a pressure plate is applied under pressure to print. It is characterized by printing sequentially with silver, silver, white, white, silver, silver, dark blue, and silver ink by the printing method. These printing inks are each coated and then dried, and again coated with other printing inks. When the first light shielding layer 30 formed in this order is provided on the first UV coating layer 20, even if light is emitted, the number, pattern or letter cannot be identified and the contents to be secured cannot be read. Finally, printing with silver ink is to make the printing state look good in the final calligraphy printing.

In addition, the aqueous coating layer 40 is formed on the first light shielding layer 30 to finally manufacture the scratch tape 2. Such an aqueous coating is to prevent peeling due to contact during storage and transportation of the product, and is formed using a conventional aqueous coating liquid.

The prepared scratch tape 2 is cut up to the fabric layer 13 in a predetermined size corresponding to a unique number or pattern portion of a lottery ticket or a card to be concealed, and the upper portion is peeled off to remove the scratched tape 2 onto the card stack 3. Attach. At this time, the letter or pattern may be printed on the aqueous coating layer 40 to induce a scratch on the security card (1).

Thus, the scratch tape 2 produced by the pressure printing can significantly reduce the material cost and labor cost compared to the conventional product 2 through the silk printing, it is excellent in light-shielding properties.

The card stack 3 is formed on the card substrate by the same method as the first UV coating layer 20 and the second UV coating layer 60 and the second light shielding layer 30. It is prepared by stacking layers 70 sequentially. At this time, the second light shielding layer 60 is formed by sequentially printing in black and white ink by the same pressure printing method as the first light shielding layer 30, and formed on the second light shielding layer 60 Print the unique number or pattern you want to secure.

In the present invention, the term "security card" is meant to include all products requiring security, such as a lottery ticket and a gift certificate, in addition to a normal card, and thus the substrate includes a card substrate of any material such as paper or plastic.

3 is a cross-sectional view showing a peeling state in the use of the tape type security card 1 according to the present invention. The tape type security card 1 of the present invention shows the paper layer 11 of the manufactured scratch tape 2. After peeling off, the adhesive layer 12 and the second light shielding layer 70 of the card stack 3 face each other and are finally manufactured. The adhesive force between the second UV coating layer 60 and the card substrate 50 is weak compared to the adhesive force between the adhesive layer 12 and the second light blocking layer 70, and when the second UV coating layer 60 is applied to the card, By peeling from the board | substrate 50, the unique number or pattern printed on the 2nd light shielding layer 50 is shielded by the 2nd light shielding layer 60, and it cannot see even if it shines light.

In addition, in order to facilitate peeling at the time of use of the security card 1, it is preferable that the scratch tape 2 is attached to a slightly larger size than the card stack 3.

Hereinafter, although an Example is given and this invention is demonstrated concretely, this invention is not limited to these examples.
