도 1은 본 발명에 따른 지문방지필름의 단면도.
도 2는 본 발명의 다른 실시 예에 따른 지문방지필름의 단면도.1 is a cross-sectional view of the anti-fingerprint film according to the present invention.
Figure 2 is a cross-sectional view of the anti-fingerprint film according to another embodiment of the present invention.

이하, 본 발명을 첨부된 도면을 참조하여 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 1에 도시된 바와 같이, 본 발명의 지문방지 필름은, 기재가 되는 필름(1)과, 상기 필름(1)의 어느 한 면 또는 양면에 도포되는 인쇄층(2), 및 상기 필름(1) 또는 인쇄층(2)의 일면 또는 양면에 코팅되는 지문방지 폴리머(3)로 형성된다.As shown in FIG. 1, the anti-fingerprint film of the present invention includes a film 1 serving as a substrate, a printing layer 2 applied to one or both surfaces of the film 1, and the film 1. Or an anti-fingerprint polymer 3 coated on one or both sides of the printing layer 2.

상기 필름(1)은, PET, PC, PI 중 어느 하나인 것이 바람직하나, 이에 한정하는 것은 아니며 지문방지 또는 오염방지를 위해 사용되는 필름이면 어느 것이든 사용 가능하다.The film 1 is preferably any one of PET, PC, and PI, but is not limited thereto. Any film may be used as long as it is used for anti-fingerprint or anti-fouling.

상기 필름(1)은, 1.5 ~ 100(㎛)임이 바람직하다.It is preferable that the said film 1 is 1.5-100 (micrometer).

상기 필름(1)이 1.5(㎛) 이하일 경우에는, 제조의 곤란성으로 제조 효율성이 떨어지고, 100(㎛) 이상일 경우에는, 유연성 및 투과성 등을 상실하여 제품의 표면에 원할하게 접착되지 못하는 문제점 및 제조단가가 상승되는 문제점이 있다.When the film 1 is 1.5 (μm) or less, the manufacturing efficiency is inferior due to the difficulty of manufacturing, and when the film (1) is 100 (μm) or more, there is a problem that cannot be smoothly adhered to the surface of the product due to loss of flexibility and permeability, etc. There is a problem that the unit price increases.

따라서, 상기 필름(1)은, 1.5 ~ 100(㎛)인 것이 바람직하다.Therefore, it is preferable that the said film 1 is 1.5-100 (micrometer).

상기 인쇄층(2)은, 지문방지 필름이 사용되는 목적에 따라 색상의 표출 또는 로고등을 인식할 수 있도록 도포 코팅한다.The printing layer 2 is coated with a coating so that it can recognize the expression of the color or logo according to the purpose of the anti-fingerprint film is used.

경우에 따라서는, 상기 인쇄층(2)은 생략 가능하다.In some cases, the printed layer 2 can be omitted.

상기 지문방지 폴리머(3)는, 상기 필름(1)에 열풍건조로 코팅 처리한다.The anti-fingerprint polymer (3) is coated on the film (1) by hot air drying.

상기 지문방지 폴리머(3)의 두께는, 10(㎚) ~ 10(㎛)임이 바람직하다.It is preferable that the thickness of the said anti-fingerprint polymer 3 is 10 (nm)-10 (micrometer).

상기 지문방지 폴리머(3)가 10(㎚) 이하일 경우에는, 상기 필름(1)에 지문방지 폴리머(3)가 고르게 분포되지 못하여 지문방지 기능이 상실되고, 10(㎛) 이상일 경우에는, 제조단가의 상승 및 필름(1)의 투과성을 저하시키는 문제점이 있다.When the anti-fingerprint polymer 3 is 10 (nm) or less, the anti-fingerprint polymer 3 is not evenly distributed on the film 1, and the anti-fingerprint function is lost. There is a problem of raising the and lowering the permeability of the film 1.

따라서, 상기 지문방지 폴리머(3)는, 10(㎚) ~ 10(㎛)인 것이 바람직하다.Therefore, it is preferable that the said anti-fingerprint polymer 3 is 10 (nm)-10 (micrometer).

도 2에 도시된 바와 같이, 본 발명의 다른 실시 예에 따른 지문방지 필름은, 필름(1)과, 상기 필름(1)의 일면 또는 양면에 도포되는 인쇄층(2)과, 상기 필름(1) 또는 인쇄층(2)의 일면 또는 양면에 코팅되는 지문방지 폴리머(3), 및 상기 필름(1) 또는 인쇄층(2)의 일면 또는 양면에 도포되는 점착제(4)로 형성된다.As shown in FIG. 2, the anti-fingerprint film according to another embodiment of the present invention includes a film 1, a printing layer 2 applied to one or both surfaces of the film 1, and the film 1. Or an anti-fingerprint polymer 3 coated on one or both sides of the printing layer 2, and an adhesive 4 applied to one or both sides of the film 1 or the printing layer 2, respectively.

상기 필름(1), 인쇄층(2), 및 지문방지 폴리머(3)은, 상술되어 있으므로, 상세한 설명은 생략한다.Since the said film 1, the printing layer 2, and the anti-fingerprint polymer 3 are mentioned above, detailed description is abbreviate | omitted.

상기 점착제(4)는, 필름(1)에 제품에 견고하게 접착 고정되도록 하는 것으로서, 접착기능을 가진 점착제이면 어느 것이든 사용 가능하다.The pressure-sensitive adhesive 4 is to be firmly fixed to the product to the film 1, any of the pressure-sensitive adhesives can be used.

상기 점착제(4)는, 필름(1)에 열간 건조로 가교하고, 그 두께는 1 ~ 100(㎛)임이 바람직하다.It is preferable that the said adhesive 4 is bridge | crosslinked to the film 1 by hot drying, and the thickness is 1-100 (micrometer).

상기 점착제(4)가 1(㎛) 이하일 경우에는, 소량의 점착성분으로 점착력을 상실하는 문제점이 있고, 100(㎛) 이상일 경우에는, 점착기능의 향상없이 대량의 점착성분의 추가로 인해 제조단가가 상승되는 문제점이 있다.When the pressure-sensitive adhesive 4 is 1 (μm) or less, there is a problem that the adhesive force is lost by a small amount of pressure-sensitive adhesive components, and when the pressure-sensitive adhesive 4 or more (100) or more, the production cost due to the addition of a large amount of pressure-sensitive adhesive components without improving the adhesion function There is a problem that is raised.

따라서, 상기 점착제의 두께는, 1 ~ 100(㎛)인 것이 바람직하다.
Therefore, it is preferable that the thickness of the said adhesive is 1-100 (micrometer).

이상에서 설명한 것은 지문방지필름을 실시하기 위한 하나의 실시 예에 불과한 것으로서, 본 발명은 상기한 실시 예에 한정되지 아니한다. 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면, 본 발명의 요지를 벗어남이 없이 다양한 변경 실시가 가능하다는 것을 이해할 수 있을 것이다.
What has been described above is just one embodiment for performing the anti-fingerprint film, and the present invention is not limited to the above-described embodiment. Those skilled in the art will appreciate that various modifications can be made without departing from the spirit of the invention.
