Problems solved by technology
[0004] However, due to the trade-off relationship between surface hardness, which indicates the hardness of the coating, and elongation, which indicates how flexible the coating is, it is not easy to provide a decorative sheet satisfying both properties
[0005] Meanwhile, regarding the realization of the matte property of the decorative board, since the conventional matting agent is porous and has a low apparent specific gravity, when it is located on the coated surface, the surface adsorption of impurities (such as fine dust, moisture, oil, etc.) increases, Even lead to deterioration of the anti-fouling property of the decorative board

Abstract
The present application relates to a laminated film that can be used in furniture or decorative materials. The present invention relates to a laminated film which is excellent in both elongation and surface hardness, which have a trade-off relationship according to the prior art, and which has a soft tactile sensation and matte characteristics, as well as excellent anti-fouling properties. In particular, the surface properties can be maintained even after the laminate film is extended.
Description
technical field [0001] The present application relates to a laminated film having a corrugated surface. In particular, the present application relates to a laminated film having an improved trade-off between elongation and surface hardness. Furthermore, the present application relates to a laminated film having excellent dirt resistance, excellent matte properties, and excellent tactile texture, wherein the laminated film of the present application can maintain the above properties even after tension is applied. Background technique [0002] Decorative sheets having matte properties (or low-gloss properties) have been widely used in the manufacture of interior materials for buildings or films for furniture. For example, there is employed a technique of manufacturing a decorative board having matte properties by coating a coating agent containing a matting agent such as silica on a substrate and curing the resulting substrate. [0003] The surface of a decorative board form...
