At this time, the substrate does not need to be a transparent material unlike in the case of the first embodiment, and the light projected from the outside of the hardcore layer 70 passes through the transparent hardcore layer 70 and the base film 40 and is a decoration coating layer. Since it reaches (30), the pattern of the decoration coating layer 30 is seen to the outside. The light that reaches the decoration coating layer 30 from the outside is shielded by the white film layer 10 on the lower surface thereof, so that it can no longer proceed and reflects back to the outside.

이상 설명한 바와 같이, 본 발명에 따른 데코레이션 필름에 의하면, 그 재료 로서 PVC를 사용하지 않으므로 친환경적인 데코레이션 필름을 제공할 수 있다. 또한, 데코레이션 필름의 소재 특성상 기재에의 부착 및 기재에의 부착시 재단이 용이하여 작업성을 향상시킬 수 있다. 또한, 종래의 PVC 재질의 데코레이션 필름은 열분해 및 황변현상이 발생되고 열에 의한 연성이 있다는 단점이 있었으나, 본 발명에 따른 데코레이션 필름은 PET 등의 결정화된 제품이라는 점에서 열적 특성이 우수하고, 경도가 높으며 열수축율이 낮으므로 PVC의 단점을 보완할 수 있다는 이점이 있다.As described above, according to the decoration film according to the present invention, since PVC is not used as the material, it is possible to provide an environment-friendly decoration film. In addition, on the basis of the material properties of the decoration film, cutting can be easily performed when adhering to the substrate and the substrate, thereby improving workability. In addition, the decoration film of the conventional PVC material has a disadvantage in that pyrolysis and yellowing occur and ductility due to heat, but the decoration film according to the present invention has excellent thermal properties in that it is a crystallized product such as PET, High and low heat shrinkage has the advantage of being able to compensate for the disadvantages of PVC.
