Description
본 발명은 유기용제, 표백제, 알칼리 성분 등의 약품과 접촉한 부위의 색상이 변하는 약품 변색 보안 용지의 제조 방법에 관한 것이다.The present invention relates to a method for producing a chemically discolored security paper in which the color of the site in contact with a chemical such as an organic solvent, a bleach, or an alkaline component changes.
은행권, 수표, 상품권 등의 유가증권과 복권, 기밀문서 등은 위조자에 의해 위조되기도 하고, 변조자에 의해 원본의 인쇄 상태를 바꾸는 변조도 행해지고 있다. 특히, 사용자가 서명 또는 금액을 직접 기재하는 수표의 경우 그 내용이 위변조자에 의해 변조되어 유통되기도 하는데, 이 경우 그 내용의 진위 여부를 판단하는 데에는 많은 노력이 필요하다. 따라서 유가증권, 복권, 기밀문서 등의 위조 및 변조가 방지되는 보안 용지가 절실히 요구되고 있다.Securities such as bank notes, checks, and gift certificates, lotteries, and confidential documents are forged by counterfeiters, and alterations are also made to change the printing state of originals by modulators. In particular, in the case of a check in which a user directly inputs a signature or amount of money, the contents may be altered and distributed by a forgery agent. In this case, much effort is required to determine the authenticity of the contents. Therefore, there is an urgent need for security papers that prevent counterfeiting and tampering of securities, lotteries, and confidential documents.
현재까지 보안을 위해 은화(隱畵, 숨은 그림), 형광 색사, 안전사(security thread) 등의 요소들이 보안 용지에 사용된 바 있다.To date, elements such as silver (hidden pictures), fluorescent color yarns, and security threads have been used for security paper.

S. Patent No. 5,123, 999 adds a dye that dissolves in organic solvents in the manufacture of paper, and contains a high viscosity containing 2,3,4-trihydroxyacetophenone (2,3,4-trihydroxyacetophenone) and carboxymethylcellulose. A method of producing paper by coating with a coating solution is disclosed. Paper produced by this method is discolored in yellow by reaction with an ink eraser, an alkaline solution, sodium sulfite and sodium bisulfite.
프랑스 특허공보 제 A-2365656 호에는 프탈레인(phthaleins) 또는 설포프탈레인(sulfophthaleins)를 첨가하여 산성 지시약에 반응하는 종이를 제조하는 방법이 개시되어 있다.French patent publication A-2365656 discloses a process for producing paper which reacts with an acidic indicator by adding phthaleins or sulfophthaleins.
프랑스 특허공보 제 E-2399503 호에는 옥시피렌트리카르복실산 (oxypyrenetricarboxylic acid)을 첨가하여 종이를 제조하는 방법이 개시되어 있다. 이 방법에 의해 제조된 종이는 잉크 지우개에 반응하여 형광 노란색으로 변색된다.French patent publication E-2399503 discloses a process for making paper by adding oxypyrenetricarboxylic acid. Paper produced by this method discolors in fluorescent yellow in response to an ink eraser.
따라서, 본 발명의 목적은 위조 및 변조가 방지되고 진위의 식별이 용이한 보안 용지의 제조 방법을 제공하는 데 있다.Accordingly, it is an object of the present invention to provide a method for producing a security paper which is prevented from forgery and tampering and is easy to identify the authenticity.
상기 목적에 따라, 본 발명에서는 수불용성이고 유기용제에 용해되는 염료 1종 이상을 지료에 가하여 습지를 제조한 후 이를 1차 건조시키고 이어서 표백제 또는 알칼리 성분과 반응하는 발색 약품 1종 이상을 포함하는 표면처리 용액으로 표면처리한 다음 건조시키는 단계를 포함하는 보안 용지의 제조방법을 제공한다.In accordance with the above object, in the present invention, a wetland is prepared by adding at least one dye which is water insoluble and dissolved in an organic solvent to a stock, and then first drying it, and then including at least one coloring agent reacting with a bleach or an alkali component.
