2. Description of the Related Art Generally, wood-cut materials made of vinyl chloride resin and diallyl phthalate resin are used as wood-cut materials used for furniture, light electric appliances, furniture, doors, shelves and the like. In particular, wood-chipped materials made of vinyl chloride resin
It is used most often as a woodcut material with a high degree of freedom such as coloring property, secondary workability, and printability.

[0003]

However, since the above-mentioned vinyl chloride resin-made wood tip material generates hydrogen chloride gas at the time of combustion, a non-vinyl chloride resin-made wood tip material has been desired from the market.

[0004] Therefore, instead of vinyl chloride resin, decorative olefin resin sheets have been produced as surface materials used for attaching surfaces of various base materials such as wall covering materials, MDF, and particle boards. However, when the thickness of the olefin resin decorative sheet is increased, or when a thick wood material having strength and strength is manufactured only by the olefin resin by lamination or the like, the primer treatment step is performed because of the non-polarity of the resin. There is a drawback that it becomes complicated and secondary workability such as cutting is not sufficient.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, the olefin resin decorative sheet manufactured as a surface material has been used as a surface portion and as a base material portion. By using an amorphous polyethylene terephthalate resin sheet and bonding them together with a two-component reaction type dry laminating adhesive,
It has been found that it is possible to produce a wood-gap material having good secondary workability and the same pattern and feel as the surface material. Furthermore,
By providing a coating layer of a primer composed of a resin binder composed of an ethylene-vinyl acetate copolymer resin and / or a thermoplastic urethane resin, and particulate silica and a solvent, on the back surface of the base material, As a result, it has become possible to produce a wood opening made of an olefin resin decorative sheet having good adhesiveness with a hot melt adhesive.

Next, an embodiment of the present invention will be described with reference to the corresponding drawings. The wood mouthpieces 10 and 20 made of the decorative olefin resin sheet of the present invention use the decorative olefin resin sheets 1 and 11 for the surface portion and the two-component reaction of the amorphous polyethylene terephthalate resin sheets 4 and 14 as the base material.
