Description

TECHNICAL FIELD [0001] The present invention relates to a decorative sheet and a method for manufacturing the decorative sheet.

The present invention relates to a decorative sheet used as a surface finishing material and a method for producing the same.

The decorative sheet, which is one of the surface finishing materials, is a sheet for representing various decorations on a molding material made of wood, furniture, doors and the like.

As the decorative sheet, a sheet made of polyvinyl chloride (PVC) having excellent workability and handling property was mainly used. However, the polyvinyl chloride sheet has a problem in that it is not environmentally friendly and harmful to the human body due to the use of a stabilizer containing a heavy metal, a phthalate plasticizer or the like in the production process.

Accordingly, in order to improve the environmental friendliness of the decorative sheet, various sheets have been developed in which a polypropylene material is applied instead of a polyvinyl chloride material. However, sheets made of polypropylene are difficult to produce through heat-pressure (heat lamination) process as a hard adhesive material, and the adhesiveness with a substrate is also poor.
