Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a security paper, and more particularly, to a security paper using an electromagnetic sensitive material and a method of manufacturing the same.
Generally, security paper includes "copy-stopping paper" that prevents copying or forgery such as securities or official documents, and "electronic paper" to prevent confidential information of companies or organizations or information that requires security from being leaked to the outside .
The principle of the " electronically sensitive paper " is that the electromagnetic field generated by the detection gate when the sensing paper containing the electromagnetic sensitive material, i.e. the " tag for detection " And the detection tag is detected due to such a change in the magnetic field.
In addition, there is a radio frequency (RF) system for recognizing, tracking and managing an IC chip to which unique identification information is input.
Security paper to which such an electromagnetic system or a radio frequency system is applied requires a special means for concealing the tag for detection in common. Conventionally, the first raw paper and the second raw paper are joined by an adhesive means, and a tag for detection is inserted therebetween. A related art has disclosed a method of manufacturing a security paper including a bonding means (Prior Art 1). However, since at least two sheets of paper are required for the manufacture of security paper, it is necessary to use a base paper having a basis weight of 40 g / m 2 or less for use in a general copying machine or a printer. Blistering occurs, and the manufacturing process is complicated, resulting in an increase in manufacturing cost. Further, since the tag for detection is a conventional filament type, there is a problem that the position is easily exposed.
Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a security paper which can hide a tag for detection even with a single sheet of paper, .
According to an aspect of the present invention, there is provided a security sheet comprising a detection tag including a magnetic powder and a coating layer formed on a surface of the base sheet on which the detection tag is printed, .
The magnetic powder may be a crystalline metal powder.
Further, the present invention may further comprise a coating layer formed on the back surface of the surface on which the detection tag is printed.
The coating layer may include a coating material, an adhesive, and an additive.
The detection tag may be formed in a pattern or a pattern.
The coating material may include at least one of fired clay, calcium carbonate and plastic.
Further, the present invention includes the following steps as a method for manufacturing the security sheet:
Printing with a magnetic ink containing a magnetic powder on one side of the base paper to form a detection tag; And
Forming a coating layer by coating a coating material on a surface of the base paper on which the tag is formed.
The manufacturing method may further include the step of forming a coating layer on the rear surface of the surface on which the tag for detecting the raw paper is formed to form a coating layer.
The magnetic powder may be a crystalline metal powder.
The coating material may include a coating material, an adhesive, and an additive.
Since the security paper of the present invention can be directly written and printed on paper coated with a paint, it can be directly used in a general OA such as a printer or a fax machine,
Further, since the tag for detection is formed of a magnetic powder, detection can be performed even if the paper is damaged due to folding, cutting, or the like.
Since the security paper of the present invention is made of a single sheet of paper, there is no layer separation phenomenon, and the bonding between the paper and the coating layer becomes stronger due to the high heat of the OA device during printing, which is excellent in durability.
According to the manufacturing method of the present invention, since the tag for detection can be formed on a paper by a printing method, pattern or pattern formation is possible and mass production is easy.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view of a conventional security paper comprising a laminate.
FIG. 2 is a photograph of a tag for detecting a filament of conventional security paper, which is made of a laminate, exposed by light.
3 is a cross-sectional view of a security sheet according to an embodiment of the present invention.
4 is a cross-sectional view of a security sheet according to another embodiment of the present invention.
5 is a flowchart illustrating a method of manufacturing a security sheet according to an exemplary embodiment of the present invention.
6 is a flowchart illustrating a method of manufacturing a security sheet according to another embodiment of the present invention.
Hereinafter, a specific embodiment of the security sheet according to the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many modifications and alternatives, all of which fall within the scope of the claims as defined by the claims. It is obvious that it can be done.
3, the security sheet of the present invention includes a sheet of
The
The raw paper can be produced by a conventional printing paper manufacturing method. Particularly, the hardwood pulp or the mixed pulp is removed from the line and processed with a refiner to an appropriate degree of accuracy (about 20 to 50 ° SR), followed by mixing chest, machine chest, fan pump, etc., and various additives including sizing agents are reacted to form a support. The ground material is uniformly injected into the head box in the cross direction. At this time, the jet ratio is operated within a range of about 0.95 to 1.05. The drying step is a step of drying the paper formed from the wire. This paper is then passed through a winder and a rewinder and wound into rolls of a suitable size in a post-process.
The basis weight of the raw paper may range from 60 g / m 2 to 100 g / m 2 . Conventional security paper produced by laminating at least two sheet will have a general printing paper having a basis weight of 70 g / m 2 to 100 g / m 2 range for use in the general printer or fax machine, so the base paper a sheet basis weight is 40 g / m 2 Or less. However, since the security sheet of the present invention uses only one sheet, it is possible to use plain printing paper having a basis weight of 60 g / m 2 to 100 g / m 2 as a base paper. The base material having a high basis weight can improve the hiding power of the detection tag.
The
The detection tag is detected through an electromagnetic sensing means. When the tag for detection passes through the sensing means, a change occurs in the alternating magnetic field of the sensing means by the magnetic powder of the tag for detection, and the spectrum of the high frequency generated by the change is detected to detect the presence of the tag for detection It informs. The sensing means generally includes a transmission coil for generating an alternating magnetic field, a reception coil for sensing a change in the alternating magnetic field generated by the transmission coil, an ac magnetic field generated in the transmission coil, And the like.
The
The adhesive may be an acrylic resin, a polyvinyl alcohol resin, a starch, a starch derivative, or a sodium silicate for fixing the coating material to the base paper and may be 0-30% by weight based on the entire coating material. The additive may include a sizing agent, a filler retention agent, and the like, and may be 0-5 wt% based on the total amount of the coating material.
In some cases, a pretreatment agent (primer) can be used so that the coating material is well formed on the detection tag on the paper.
In addition, as shown in FIG. 4, the present invention can further form a
The security paper according to the present invention can be printed using a general OA device such as a general printer or a fax machine. Since the paper is one sheet, the paper having high basis weight can be used, thereby improving the hiding power of the tag for detection by the paper itself, the layer separation phenomenon occurring in the lumber does not occur, It is possible to strengthen the durability of the security paper by strengthening the coupling between the original paper of the security paper and the coating layer.
