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 paper 10, a detection tag 30 formed entirely or partially on one side or both sides of the sheet of paper, and a coating layer 20 ).

The ground paper 10 is a hardwood pulp, and may be mixed with softwood pulp or recycled pulp up to 80%. However, the composition of the paper is not limited thereto, and may be differently configured depending on the use or quality of the printing paper.

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 detection tag 30 may be formed entirely or partially on one side or both sides of the paper. The tag for detection is formed by printing a magnetic ink made of magnetic powder on a paper. The magnetic powder body may be a crystalline metal powder. Since the magnetic powder body is used, it is possible to print a detection tag having a pattern or a pattern, and the detection tag printing process is simplified, so that mass production is easy, and the manufactured security paper has a position The exposure problem can be solved and the magnetism of the tag for detection can be maintained even if the sheet is damaged due to folding or cutting. Further, the detection tag is improved in detection area because the area of the detection tag is wide.

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 coating layer 20 is formed by coating a coating material on a surface on which a tag for detecting a raw paper is printed. The coating layer conceals the detection tag printed on the base paper so that the printed position of the detection tag is prevented from being exposed to the outside, and the base paper can be printed on security paper using a general OA device such as a printer or a fax machine. Coating materials include paints, adhesives and additives. The coating material may include at least one of a calcined clay, calcium carbonate or plastic having a high scattering coefficient except for titanium dioxide as a white pigment.

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 second coating layer 40 on the rear surface of a paper sheet on which a tag for detection is not formed. It is possible to increase the hiding power of the detection tag and improve the whiteness of the security paper by forming the coating layer on both sides of the paper.

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.
