Description

Film for preventing forgery and application product thereof {A Film for Preventing Forgery and Falsification and Product for Application}

The present invention relates to an anti-counterfeiting film using a combination of a scintillation layer and a polarizing layer and an application product thereof. It relates to a film and its application products.

With the development of information and communication technology along with the industrial development of the 21st century, the level of awareness of general users about commercial products and technologies is increasing. It is becoming a serious social problem.

In particular, the increasing popularity of color copiers and other imaging systems, and the improved technical quality of color copying, have led to an increase in counterfeiting of banknotes, passports, authentication labels, and identification cards, and the like. For this reason, interest in all industries is focused on anti-counterfeiting and falsification prevention technology that has been limitedly applied like banknotes in the past.

In relation to the forgery prevention technology, in recent years, a two-dimensional code reader represented by a quick response (QR) code using a grid pattern on a plane to contain more information than a conventional one-dimensional code has been widely used. A QR code is a two-dimensional barcode in a matrix format that displays information in a black and white grid pattern. QR codes are being used in various fields due to the advantage of being able to store data of a larger size than general barcodes that store numeric or character information in one direction. In general, the QR code can read stored data through image capturing through a camera provided in a smart phone or the like or a device having a separate reader. That is, any user who has the means to read the standard QR code can view the data in the QR code.

However, in the case of QR codes, light and focal length are sensitive problems during code recognition, so NFC is increasingly used as a field of RFID technology. NFC is a technology that can exchange data between terminals in a contactless short distance (within about 10cm) using the 13.56 Mhz frequency band, and is widely used as a payment method. It is becoming a possible tool.

On the other hand, various technologies have been proposed to prevent counterfeiting and alteration of expensive goods or goods requiring authenticity of contents. Conventionally, techniques using mainly fine patterns, braille, holograms, RFID, etc. have been used to prevent counterfeiting and falsification of products, but these prior technologies have limitations in that it is not easy for general users to distinguish whether or not products are forged or tampered with. There is a problem in that it has or requires a lot of cost to manufacture anti-counterfeiting and tamper-proof means.

Looking at the patents and utility model literature on forgery prevention means using RFID, which is one of the prior art, KR Patent Application No. 10-2010-0030842 (Title of the Invention: RFID tag for copy protection, copy prevention system using the same) and method) satisfies the EPC standard and includes: a first memory bank in which information arbitrarily input by a user is stored; a second memory bank in which tag ID information for a corresponding tag is stored; a third memory bank interworking with the tag ID information to store EPC (electronic product code) information on the object to which the tag is attached; and an access password area in which an access password for controlling access to the tag is stored, accessible through the access password and assigned in connection with the EPC information of the object to be the target of determining the uniqueness of the RFID tag Disclosed is an RFID tag for copy protection including a fourth memory bank having a kill password area in which secret information is stored.

However, in the case of the above-described RFID tag for preventing copying, there is a problem in that whether or not forgery can be determined only through an RFID reader and cannot be confirmed with the naked eye.

Numerous papers and patent documents are referenced throughout this specification and their citations are indicated. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to more clearly describe the level of the technical field to which the present invention pertains and the content of the present invention.

Examples of articles including the anti-counterfeiting film according to the present invention can be applied in various ways, and are not interpreted as being limited to the following examples, but all changes, equivalents or substitutes included in the spirit and scope of the present invention should be understood as including

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an anti-counterfeiting film included in various application products, comprising: a base layer; a design print layer located on the upper side of the substrate; and a polarizing layer positioned above the design print layer and including a liquid crystal material layer; It is positioned above the polarizing layer and characterized in that it comprises a scintillation layer including a nano-imprinting layer.

Here, the scintillation layer causes the birefringence of the light reflected from the polarization layer to change the unique color or shape of the polarization layer, thereby hiding the properties of the material of the existing polarization layer, thereby providing difficulty in duplication. .

In addition, since the birefringence may vary according to the thickness of the scintillation layer, various colors may be realized. As the thickness of the scintillation layer becomes thicker, the refractive index increases and the diffraction wavelength becomes shorter, so that a color with a short wavelength (eg, a color of blue to purple color) is implemented.

For the base layer of the anti-counterfeiting film of the present invention, a film made of a known synthetic resin may be used.

The polarizing layer of the forgery prevention film of the present invention may be an ink containing cholesteric liquid crystal, and the pattern and printing of the polarizing layer may be performed using known methods such as silk screen, offset, flexo, gravure, ink-jet or comma. It may be implemented as a coating.

The polarizing layer for forgery prevention of the present invention, the glare layer may be manufactured using a polymer mold, and may be manufactured by imprinting a polymer mold surface having ductility in a specific pattern.

The nano-imprinted pattern of the forgery prevention film of the present invention may be formed using a known transfer method.

The scintillation layer including the nano-imprinting layer of the forgery prevention film of the present invention is characterized in that the color or shape confirmed with the naked eye changes when receiving light, preferably when light generated from a flash for photographing or video recording is received. It is characterized in that the color or shape confirmed with the naked eye changes.

Here, it is a very important configuration that a color or shape identified with the naked eye changes when light generated from a flash for photographing or moving pictures is received. This is because, when the color or shape that can be seen with the naked eye changes when receiving the light from the flash for taking photos or videos, it is possible to check whether the color or shape has changed through the screen of a smartphone, etc. can be used for precise comparison.

The application product to which the anti-counterfeiting film of the present invention is applied is money for exchanging goods, where the anti-counterfeiting film of the present invention may be positioned 70 on a hologram of money. In particular, in the case of money, since it is continuously used by many people, there is a risk that the glare layer showing a change in color or shape may be damaged. Therefore, the anti-counterfeiting film of the present invention included in the application product may further include a glare layer-reinforced protective film 60 on the upper side of the glare layer in consideration of the above problems.

On the other hand, application products to which the anti-counterfeiting film of the present invention is applied may be mainstream. In particular, the anti-counterfeiting film of the present invention is preferably located on the lid portion of the alcoholic beverage, preferably the upper end 80 of the alcoholic beverage lid for the ease of the user's forgery confirmation.

The application product to which the forgery prevention film of the present invention is applied may be a genuine sticker label or a genuine sticker film 90 .

The size of each pattern included in the glare layer of the forgery prevention film of the present invention may be 10 μm or less, preferably 1000 nm (1 μm) or less, and most preferably 500 nm or less. That the size of each pattern present in the scintillation layer is within the above range is an important configuration from the viewpoint of vividness of the implemented color. In particular, it is important to set the height and horizontal pattern of the scintillation layer differently for each location because a color or shape that can be confirmed with the naked eye may vary depending on the height and horizontal pattern of the scintillation layer. By setting the height and horizontal pattern of the flash layer differently depending on the embodiment, the user can determine a reference color or shape for detecting forgery.

The difference in refractive index between the film of the scintillation layer and the nano-pattern layer included in the forgery prevention film of the present invention is preferably 1.0 or less. Even when the difference in refractive index between the film of the scintillation layer and the nano-pattern layer is 1.0 or less, the shape that can be confirmed with the naked eye may be different. By setting the refractive index difference between the film of the scintillation layer and the nano-pattern layer to be 1.0 or less, the user can determine a reference color or shape to detect forgery.

The thickness of the scintillation layer included in the forgery prevention film of the present invention is preferably thinner than the thickness of the polarizing layer. The thinner the glare layer and the thicker the polarizing layer, the clearer the implemented color or shape.

Here, the thickness of the scintillation layer is preferably about 10 to 25㎛.

The anti-counterfeiting film of the present invention is characterized in that two or more types of colors that can be confirmed with the naked eye appear when receiving light. Furthermore, the forgery prevention film may be partitioned, and the partitioned portions may be printed to represent different colors.

Here, printing so that two or more types of forgery prevention films constituting the present invention appear is a very important configuration. This is because, when the anti-forgery film of the present invention is printed so that two or more kinds of colors appear, the nano-imprinting layer must be accurately printed so that two or more different colors appear, so that the possibility of forgery can be significantly reduced.

The anti-counterfeiting film of the present invention is characterized in that it includes an electronic tag capable of performing an authentication procedure for whether or not forgery is performed by a computer. Furthermore, the electronic tag in which the authentication procedure for forgery or not is implemented by the computer preferably includes additional information in addition to the authentication procedure information on whether forgery or not. It is a very important configuration that the electronic tag to which the forgery prevention film of the present invention is applied includes additional information in addition to the authentication procedure information on whether or not forgery or not. This is because, when distribution information, price information, or country of origin information is added to the electronic tag in addition to information on whether or not forgery or not, various functions can be performed with one electronic tag.

For an electronic tag including a QR code and an anti-counterfeiting film according to an embodiment of the present invention, forgery using a computer built in a smartphone and an electronic tag in the process of taking a QR code to check the QR code using a smartphone application It is possible to simultaneously proceed with the primary authentication of whether or not there is a forgery, the secondary authentication of forgery using the computer and QR code built into the smartphone, and the tertiary authentication of whether or not forgery using the color or shape change of the anti-counterfeiting film.

Here, the tertiary authentication for the above-described forgery or not may be made through visual identification or a shape and/or shape comparison means built into a smartphone application.

In the present invention, it is a very important configuration that the authentication procedure for forgery or not is implemented using an electronic tag, QR code, and an anti-counterfeiting film that can confirm whether a color or shape has changed with the naked eye. Because primary authentication through electronic tag, secondary authentication of forgery using a computer and QR code in the process of shooting QR code to check QR code This is because the third authentication of whether or not forgery can be carried out at the same time can further reduce the possibility of forgery.
