Abstract

Thin coating layer of this compn. for opaque synthetic resin print paper enabled a photographic emulsion or printing ink to absorb and preserve in good condition. Thus, 3 g nitro cellulose was dissolved in a mixed solvent of 50 ml methanol and 50 ml methylethylketone and then 2 g gelatin-dissolved acetic anhydride 5 ml added to give coating compn. for synthetic resin print paper.

Description

인화지용 수지필림의 도포액 조성물Coating liquid composition of resin film for photo paper

본원 발명은 백색 수지필림의 상면에 도포화하여 그상면에 사진 감광 유체와 인쇄잉크 및 기재 잉크가 잘 흡착 보존될 수 있는 피막층을 형성시키는 인화작용 수지필름의 도포액 조성물에 관한 것이다.The present invention relates to a coating liquid composition of a ignition resin film which is coated on an upper surface of a white resin film to form a coating layer on which the photosensitive fluid, printing ink, and base ink can be adsorbed and stored well.

종래의 신분증 사진용 인화지는 고가인 고급 바라이다지상에 사진 감광유체를 도포건조하여 만들었는데 바라이다지가 흡수성인 섬유로 되어 있어 사진이 오손되기 쉽고 찢어지거나 구겨지기 쉬운데 특히 물이 묻었을 때에는 그와 같은 폐단이 더욱 심하였다.Conventional photo paper for photo identification is made by applying a photosensitive fluid to a high-quality barrier paper, which is expensive, and the barrier paper is made of absorbent fibers, making it easy to be damaged and torn or crumpled. The lung was worse.

그러므로 전기와 바와같은 결함을 적게하기 위하여 신분증의 표면에 수지막을 형성시키는 등의 번거로운 과정을 실시하였으나 그 수지막이 사진 및 신분증표면에서 박리되는 일이 있어 소기의 목적을 다할수 없었다.Therefore, in order to reduce defects such as electricity, a cumbersome process such as the formation of a resin film on the surface of the identification card was performed, but the resin film may be peeled off from the surface of the photo and ID card, and thus the purpose was not fulfilled.

출원인은 전기한 바와같은 종래의 신분증용 인화지의 단점을 없애고 사용이 간편하며 내구성이 있는 신분증 인화지용 수지필림을 창안하기 위하여 많은 실험을 실시하여 본 발명의 조성물을 완성하였는데 그실시예는 다음과 같다.Applicant has completed the composition of the present invention by carrying out a number of experiments to eliminate the disadvantages of the conventional photo ID paper as described above and to create a resin film for ID photo paper that is easy to use and durable. .

[제1공정(본발명의 조성물의 제법)][First step (manufacturing method of composition of this invention)]

메탄올 50ml에 메칠에칠케톤 50ml를 혼합한 용액에 약 3g의 니트로 셀루로우즈를 용해시켜 A액으로하고 따로 빙초산 5ml에 제라틴 2g을 가하고 가열용해하여 B액으로 한다.Dissolve about 3 g of nitro cellulose in 50 ml of methanol and 50 ml of methyl ethyl ketone to make A solution. Separately, add 2 g of gelatin to 5 ml of glacial acetic acid, dissolve it, and make B solution.

다음 A액을 잘 교반하면서 서서히 B액을 가하여 본 발명의 조성물을 얻는다.Next, liquid A is gradually added while stirring well, and the composition of this invention is obtained.

[제2공정][Step 2]

적당한 두께의 백색 불투명한 수지필림 특히 염화수지필림의 표면에 제1공정에서 얻어진 조성물을 고르게 도포후 건조시켜 피막을 형성시킨다음 그 표면에 신분증에 필요한 인쇄사항을 인쇄하고 어두운 곳에서 사진 인화할곳에 공지의 감광유제를 도포건조하여 신분증인화지용 수지필림을 제조한다.Apply the composition obtained in the first step evenly on the surface of the white opaque resin film, especially the resin film film, of suitable thickness and dry it to form a film. Then print the prints necessary for identification card on the surface and place it in the dark A known film emulsion is applied and dried to prepare a resin film for identification photo paper.

본 발명의 특징과 작용효과는 다음과 같다.Features and effects of the present invention are as follows.

수지필림 표면에 신분증의 인쇄를 하거나 감광유제를 도포하면 인쇄잉크가 지워지고 감광유제가 쉽게 박리되는데 그 필림표면에 인쇄잉크나 감광유제를 잘흡착 보존할수 있는 피막을 형성시키더라도 그 피막이 수지필림으로부터 쉽게 박리되어 소기의 목적을 다할수 없었다.When printing ID card or applying photosensitive emulsion on the surface of resin film, printing ink is erased and photosensitive oil is easily peeled off. Even if the film is formed on the surface of the film to adsorb and preserve printing ink or emulsion, It peeled and could not fulfill its intended purpose.

그러나 본 발명의 조성물을 도포건조후 인쇄와 사진유제를 도포한 인화용 백색불투명한 수지필림 특히 염화비닐 수지필림은 조성물에 들어있는 메탄올과 메칠에칠케톤에 의하여 수지필림 표면이 약간 용해연화되고 그 상면에 니트로 셀룰로우즈와 제라틴의 혼합피막이 형성되어 수지필림의 표면에 견고하게 고착되고 또한 그 혼합피막이 감광유제를 견고하게 접착시킴과 동시에 인쇄용 잉크나 기재용 잉크를 잘 흡착 보존 하는 것으로 특히 염화 비닐 수지를 사용하면 전기한 바와같은 접착등이 더욱 좋아진다.However, the white opaque resin film for printing and photo-emulsion after application of the composition of the present invention, especially the vinyl chloride resin film, is slightly dissolved and softened by the methanol and methyl ketone in the composition. A mixed film of nitro cellulose and gelatin is formed on the upper surface to firmly adhere to the surface of the resin film, and the mixed film firmly adheres to the photosensitive emulsion and adsorbs and preserves printing ink or substrate ink. The use of vinyl resin improves the adhesion as described above.

본 발명의 신분증 인화지용 수지필림은 전기한 바와같은 장점이 있고 또한 사진 인화시에 현상액이나 정착액의 손실이 적고 세척액이 적게들어 그 사용이 간편하고 신분증이 오손되거나 구겨지는 율이 극히 적은 등의 작용효과가 있다.The resin film for ID card photo paper of the present invention has the advantages as described above, and also has a small loss of developer or fixer when photographic prints and a small amount of cleaning solution, so that its use is simple and the ID card is not damaged or crumpled. It works.
