There is also a method of producing a polyester decorative board having an uneven pattern on the surface by providing unevenness on the surface of a vinylon film. To create unevenness on the surface of the vinylon film used in this method, the vinylon film is embossed to make it uneven, the resin is raised in a pattern on the surface of the vinylon film, and the uneven original is coated with polyvinyl alcohol resin. There are various methods such as forming a film and peeling it off.
From the viewpoint of reproducibility of unevenness, expression of appearance of natural products, etc.
An excellent method is to coat the manuscript with resin.

However, in order to form a film by coating polyvinyl alcohol resin, it is necessary to heat and dry it to remove moisture, and if the amount of resin applied is large, it takes time to dry, which reduces productivity. is expensive, and if the amount of coating is small, the strength of the imprinted film will be insufficient, making it unusable or unable to be used repeatedly.

(Means for Solving the Problems) The present invention uses a backing film to increase the durability of the imprinted film. , is characterized in that a nylon film having a moisture permeability of 200 g/m 2 /24 hr or more is used as the backing film.

In the manufacturing method of the present invention, first, an aqueous solution of polyvinyl alcohol resin is applied to the surface of a manuscript made of natural wood or the like, and a nylon film is superimposed and laminated thereon.

The nylon film is laminated before the polyvinyl alcohol resin is dried. This makes it possible to bond and integrate the nylon film and the polyvinyl alcohol resin film without using an adhesive or the like, and has the effect of preventing the occurrence of wrinkles, increase in the number of steps, etc. due to the use of adhesives.

The nylon film used has its adhesion surface treated with corona discharge treatment to further strengthen the adhesion with the polyvinyl alcohol resin film, and is also moisture permeable to allow the moisture in the polyvinyl alcohol resin to evaporate. Use a material with a weight of 200g/m 2 /24hr or more.

After laminating the nylon film, it is heated to remove the moisture in the polyvinyl alcohol resin.
The polyvinyl alcohol resin is formed into a film and adhered to the nylon film, and then peeled off from the original to obtain a shaped film.

Polyvinyl alcohol resin has a saponification degree as high as possible, and a higher degree of polymerization is desirable because it has better resistance to polyester resin, but if the viscosity becomes too high, the solubility (concentration) will decrease and workability will decrease. Since it falls, the degree of saponification is 97-99%
A degree of polymerization of 500 to 1000 is desirable.

Further, it is preferable that the polyvinyl alcohol resin aqueous solution is vacuum defoamed as much as possible in advance in order to prevent bubbles from being generated later. The backing film should be one that has good adhesion to the polyvinyl alcohol resin and allows the moisture in the polyvinyl alcohol resin to escape easily when heated, and should be a nylon film with a moisture permeability of 200 g/m 2 /24 hr or more that has been subjected to corona discharge treatment. Use.

It is also possible to form a molded film by forming a film of polyvinyl alcohol alone without using a backing film, but it tends to "repel" and a smooth film cannot be obtained due to poor leveling. In addition, since the strength is weak, a molded film using a backing film is better.

Next, the water in the aqueous solution is volatilized through the film by placing it in an oven at 80℃ for 1 hour, and then peeling it off from the mold.The result is a polyester decorative board that integrates a polyvinyl alcohol resin film with an uneven wood grain pattern and a nylon film. A shaped film was obtained.
