Benefits of technology

[0008]It is an object of the present invention to provide a scratch tape capable of enhancing security reliability by forming a lightproof layer on the scratch tape using a platen press, and protecting the lightproof layer from being scratched during a transport and storage by forming a water-based coating layer on the lightproof layer.
[0009]It is another object of the present invention to provide a method for manufacturing an improved scratch tape capable of enhancing security reliability.

Problems solved by technology

However, this silkscreen process causes the ink to be thickly doped, resulting in wasting of the ink.
Furthermore, the silkscreen process has some drawbacks in that the security required area can be read without scratching off the silver ink-doped layer such that the security is not reliable.
Also, the ink layer can be unintentionally scratched during a transport and storage since the doped surface is not even.

Embodiment Construction

[0016]A preferred embodiment of the present invention will be described hereinafter with reference to the accompanying drawings.

[0017]FIG. 1 is a cross-sectional view illustrating a layered structure of a scratch tape according to a preferred embodiment of the present invention.

[0018]As shown in FIG. 1, a scratch tape sheet 1 according to a preferred embodiment of the present invention comprises a base substrate 10, an ultraviolet (UV) coating layer 20, a lightproof layer 30, and a water-based coating layer 40 deposited in sequential order.

[0019]The base substrate 10 comprises a carrier web 11, an adhesive layer 12, and a fabric 13 orderly deposited such that the fabric 13 is applied to an upper surface of the carrier web 11 with the adhesive layer 12.

[0020]In this embodiment of the present invention, the carrier web 11 is a light blue or white draft paper of the Fuji company, and the adhesive layer 12 is a conventional polyurethane and synthetic rubber adhesive as it is or attenuat...

Abstract

A scratch tape includes a base substrate, a UV coating layer formed on the upper surface of the base substrate, a lightproof layer 30 formed of the UV coating layer for shielding light, and a water-based coating layer 40 such that the enhanced lightproof property provides the security-required products with the reliable security, and is manufactured using the platen press printing such the whole manufacturing costs can be reduced.

Description

BACKGROUND OF THE INVENTION[0001](a) Field of the Invention[0002]The present invention relates to a scratch tape and a method for manufacturing the same, and in particular, to a scratch tape and its manufacturing method capable of improving lightproof property thereof.[0003](b) Description of the Related Art[0004]Recently, issued are various cyber lottery tickets, pre-paid cards, phone cards, and gift certificates having secret numbers of winning numbers, and the numbers are secured using various techniques until the tickets / cards are sold.[0005]One of the techniques is to apply a tape processed by a silk screen-printing thereon. The tape is manufactured by applying a fabric such as PET 50th micro polyester on a light blue or white kraft paper, manufactured by the Fuji company, with an adhesive and then required areas of the tape is doped with silver ink using the silk screen process. However, this silkscreen process causes the ink to be thickly doped, resulting in wasting of the in...
