Description

이중패턴이 형성된 데코시트 {DOUBLE PATTERNED DECORATION SHEET}Deco sheet with double pattern {DOUBLE PATTERNED DECORATION SHEET}

본 명세서에 개시된 내용은 이중패턴이 형성된 데코시트에 관한 것이다.The content disclosed in this specification relates to a deco sheet having a double pattern formed thereon.

최근 스마트폰, 태블릿PC 등의 전자기기의 외장재에 데코필름을 적용하여 외장재를 보호하면서도 원하는 색상과 무늬를 구현하고 있다. 소비자들은 전자기기의 기능뿐만 아니라 전자기기의 디자인을 중시하기 때문에 다양한 디자인이 연구되고 있는 실정이며, 현재 전자기기 분야에서는 금속성 디자인이 가장 각광받고 있다. 금속은 고유의 광택, 우수한 휘도 등 디자인 측면에서는 매우 우수하나 중량이 무겁고 제작 비용이 높을 뿐만 아니라 전파를 차단하는 단점이 있다. 이를 보완하기 위하여, 금속 대신 글래스 또는 투명 플라스틱을 적용하고 있으나 금속 대비 강도가 낮고 특히 충격에 약하다는 단점이 있다. Recently, deco films have been applied to the exterior materials of electronic devices such as smartphones and tablet PCs to protect the exterior materials while realizing desired colors and patterns. Because consumers value not only the function of electronic devices but also the design of electronic devices, various designs are being researched, and metallic designs are currently receiving the most attention in the field of electronic devices. Metal is excellent in terms of design, such as its inherent gloss and excellent brightness, but it has the disadvantage of being heavy and expensive to manufacture, as well as blocking radio waves. To compensate for this, glass or transparent plastic is used instead of metal, but it has the disadvantage of being less strong than metal and being particularly vulnerable to impact.

이와 같은 문제를 개선하기 위한 방법으로서, 특허문헌 1에서는 기재층으로 폴리에틸렌테레프탈레이트(PET)를 적용한 데코레이션 필름을 개시하고 있으나, 폴리에틸렌테레프탈레이트의 경우, 강성으로 인해 반복 굽힘 환경에서 쉽게 파손될 뿐만 아니라 제조과정 중 환경오염을 유발할 수 있다. 또한, 특허문헌 1에서는 데코레이션 코팅층을 단층으로 구비하고 있어 소비자가 원하는 수준으로의 디자인 구현이 어려운 문제점이 있었다. As a method to improve this problem, Patent Document 1 discloses a decoration film using polyethylene terephthalate (PET) as a base layer. However, in the case of polyethylene terephthalate, it is not only easily damaged in repeated bending environments due to its rigidity, but also difficult to manufacture. It may cause environmental pollution during the process. In addition, in Patent Document 1, the decoration coating layer was provided as a single layer, so there was a problem in that it was difficult to implement the design at the level desired by consumers.

This adhesive layer 30 may contain a polymer resin and a curing agent, and the polymer resin may include at least one selected from polyester resin, acrylic resin, alkyd resin, and amino resin, preferably an acrylic resin with excellent yellowing and dispersibility. It is desirable to use The curing agent may be one or more selected from isocyanate curing agents, epoxy curing agents, and aziridine curing agents. However, as long as it is a material capable of curing the polymer resin, its use is not significantly limited.

한편, 상기 제1 필름(10) 및 제2 필름(20) 상에는 각각 증착층 및 인쇄층 중에서 선택되는 하나 이상이 더 구비될 수 있다.Meanwhile, one or more layers selected from a deposition layer and a printing layer may be further provided on the first film 10 and the second film 20, respectively.
