Title:
NATURAL-WOOD THIN PAPER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/174120
Kind Code:
A1
Abstract:
Provided is a natural-wood thin paper in which the texture of natural wood is retained, colors are visible in a clear manner, and a desired color can be obtained. Also provided is a method for manufacturing the natural-wood thin paper. A backing sheet (8) is bonded to the rear surface of an ultra-thin veneer (1) made of natural wood, and a pigment-containing resin is impregnated into the vessels of the ultra-thin veneer (1). The natural-wood thin paper (A) is produced by: a lamination/coloring step I in which the backing sheet, which is primarily made of paper or a nonwoven, is bonded using an adhesive containing a pigment raw material to the rear surface of a veneer obtained by slicing natural wood; and a grinding/polishing step II in which the backing sheet of the veneer is polished using a grinding/polishing machine to obtain an extremely thin veneer having a thickness of 0.05-0.1 mm. Because both the earlywood and latewood constituting the wood material are impregnated with the pigment-containing resin, coloring is obtained without any change to the contrast in the wood grain, and it becomes possible to finish the natural-wood thin paper into a decorative plate having a discretionary color while maintaining the characteristics of natural wood.
