Abstract

The present invention provides an interior film having a transverse hairline implemented therein and, more specifically, provides an interior film (F) having a transverse hairline implemented therein, comprising: a transparent plastic film layer (30); an UV imprinting layer (50) which has a transverse hairline implemented therein and is formed below the transparent plastic film layer (30); and a metal deposition layer (70) formed below the UV imprinting layer.

First claim

What is claimed is:

1. An interior film having transverse hairlines implemented therein comprising:
a transparent plastic film layer;
an UV imprinting layer which has transverse hairlines formed therein and is formed below the transparent plastic film layer; and
a metal deposition layer formed below the UV imprinting layer,
wherein the UV imprinting layer is formed by applying an ultraviolet-curable resin composition to one side of the transparent plastic film layer, imprinting a ultraviolet-curable resin composition applied to the transparent plastic film layer with a forming roller in which transverse hairlines are formed, and curing the ultraviolet-curable resin composition with ultraviolet rays,
wherein the transverse hairlines formed in the UV imprinting layer are formed perpendicularly to the length direction of the interior film, have various lengths and average roughness (Ra) within the ranges of the length of 0.1 to 100 mm, and the average roughness of 0.1 to 10 μm, and are 20 to 350 per unit length of 1 cm in the number of lines.

2. The interior film according to claim 1 , further comprising:
an adhesive layer formed below the metal deposition layer.

3. The interior film according to claim 1 , further comprising:
a base layer formed below the adhesive layer.

4. The interior film according to claim 1 , wherein the transparent plastic film layer is one selected from a polyethylene terephthalate (PET) film, a polybutylene terephthalate (PBT) film, a polypropylene (PP) film, a polyethylene (PE) film, a poly vinyl chloride (PVC) film, a poly methyl methacrylate (PMMA) film, an acrylonitrile-butadiene-styrene (ABS) film, a polycarbonate (PC) film and a styrene-acrylonitrile copolymer (SAN) film.

5. The interior film according to claim 1 , wherein the transparent plastic film layer is 20 to 200 μm in thickness.

6. The interior film according to claim 1 , wherein the UV imprinting layer is made of ultraviolet-curable resin composition containing acrylate oligomers, monomers, photoinitiators, and additives.

7. The interior film according to claim 6 , wherein the acrylate oligomer is one selected from urethane groups, epoxy groups, ester groups, ether groups and silicon groups.

8. The interior film according to claim 6 , wherein the ultraviolet-curable resin composition has 30 to 100 weight % of solid.

9. The interior film according to claim 1 , wherein the UV imprinting layer is 2 to 80 μm in thickness.

10. The interior film according to claim 1 , wherein the transverse hairlines formed in the UV imprinting layer have various lengths and average roughness (Ra) within the ranges of the length of 0.1 to 10 mm, and the average roughness of 0.2 to 0.7 μm and are 80 to 140 per unit length of 1 cm in the number of lines.

11. The interior film according to claim 1 , wherein the metal deposition layer is formed below the UV imprinting layer 50 by deposition of one selected from aluminum, chrome, zinc, copper, stainless steel, gold, silver, nickel, cobalt, iron, tin and sten.

12. The interior film according to claim 1 , wherein the metal deposition layer is 100 to 1,000 Å in thickness.

13. The interior film according to claim 1 , wherein the metal deposition layer is substituted with a pearl coating layer or a printing layer.

14. The interior film according to claim 13 , wherein the pearl coating layer is formed by a calcium aluminum borosilicate-based pigment.

15. The interior film according to claim 2 , wherein the adhesive layer is formed polyurethane-based, polyester-based or epoxy-based adhesives and is 1 to 20 μm in thickness.

16. The interior film according to claim 15 , wherein the adhesive contains a pigment.

17. The interior film according to claim 3 , wherein the base layer is one selected from a poly vinyl chloride (PVC) film, a polypropylene (PP) film, a polyethylene (PE) film, an acrylonitrile-butadiene-styrene (ABS) film, a polycarbonate (PC) film and a styrene-acrylonitrile copolymer (SAN) film and a poly methyl methacrylate (PMMA) film.

18. The interior film according to claim 17 , wherein the film is a colored film.

19. The interior film according to claim 3 , wherein the base layer is 30 to 300 μm in thickness.

20. The interior film according to claim 1 , further comprising:
a first primer layer formed on the transparent plastic film layer.

21. The interior film according to claim 1 , further comprising:
a second primer layer formed between the transparent plastic film layer and the UV imprinting layer.

22. The interior film according to claim 1 , further comprising:
a third primer layer formed between the UV imprinting layer and the metal deposition layer.

23. The interior film according to claim 20 , wherein the first primer layer, the second primer layer and the third primer layer are formed by coating acryl-based resin, acrylurethane-based resin or epoxy-based resin.

24. The interior film according to claim 20 , further comprising:
a surface coating layer formed on the first primer layer.

25. The interior film according to claim 24 , wherein the surface coating layer is formed by an ultraviolet-curable resin composition or a thermo-hardening resin composition.

26. The interior film according to claim 24 , wherein the surface coating layer is 1 to 30 μm in thickness.

27. The interior film according to claim 3 , further comprising:
a release sheet which is disposed below the base layer and on which an adhesive is coated.

28. The interior film according to claim 27 , wherein the adhesive is a hot melt type adhesive.
