Abstract

PURPOSE:To enrich the luster and depth of a wooden base material and to add a high class feeling to said material, by forming on the surface of said wooden base material through an adhesive agent, a pearl ink layer, a foundation printing layer, a tone printing layer and a conduit printing layer sequentially in this order, each layer partially blanked. CONSTITUTION:A transfer sheet is roughly divided into two layers, namely, a basic separating sheet 1 and a transfer layer 2 to be transferred onto a wooden base material 3. The transfer layer 2 is formed on a pearl ink layer (a), a foundation printing layer (b), a tone printing layer (c) and a conduit printing layer (d). The transfer sheet is laminated onto wooden base material 3 through an adhesive 4. It is desirable that the conduit printing layer (d) and the tone printing layer (c) are printed, similarly to the other printing layers (a) and (b), by an ink having a vinyl chloride-vinyl acetate copolymer as a binder. The foundation printing layer (b) is printed so that it is partially provided with unprinted blanks. Although the pearl ink layer (a) is desirable to be printed by titanium coated mica, copper or zinc may be employed for printing. Printing is carried out with the use of an accented plate having blanks formed on a shaded form plate obtained on the basis of a model of an aimed natural wood.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a makeup (fabric) that takes advantage of the material window of the transfer base material and has an improved design through a printed pattern, and a method for producing the same.

This decorative board is used for furniture, fittings, housing materials, etc.

<Conventional technology> A technique for producing a decorative board that resembles natural wood (e.g. oak), which is different from the wood substrate (e.g. lauan plywood) by providing an ink layer on the surface of a wood base material such as lauan plywood. is well known. In this case, the ink layer consists of three layers, and these three layers consist of, in order from the surface side of the wood base material, a base printing layer, a tone printing layer, and a conduit printing layer. The base printing layer is usually dark throughout and has a color tone that is the desired base of natural wood. The tone printing layer has a darker color than the base printing layer and is printed with wood grain shading, and the base printing layer can be seen through the areas where the density is light or where it is not printed at all.

The conduit printing layer is a layer in which only the conduit is printed with dark ink. Methods for forming these printed layers include printing directly on the wood base material, as well as printing these printed layers on a release sheet and then using an adhesive etc. to remove these printed layers. There is a method of transferring to a wood base material, but the above three printing layers are all the same.

By the way, natural wood has a unique texture, depth, and wood texture, so in order to create a decorative board that is close to natural wood, it is necessary to reproduce this texture, depth, and wood texture. For this reason, instead of printing 11 layers all over the base, there is a method of making a partial cutout and printing it so that the wood base material can be seen through the cutout. The base material that can be seen through is the wooden base material of lauan plywood, so the texture, depth, and wood texture can be maintained as is.

<Problems to be Solved by the Invention> In this way, if a cut-out part is provided in the base printing layer so that the wooden base material can be seen through, the part to be seen through is made of cheap wood such as lauan plywood. It is not possible to obtain a decorative board with a luxurious design.

Therefore, the present invention utilizes an inexpensive wood base material to create a textured texture.
Provides a method for producing a decorative material that has depth and wood texture, and also uses pearl effect to enhance the texture and depth of a wood base material, giving it a luxurious feel, and the decorative board obtained in this way. The purpose is to

<Means for Solving the Problems> In order to achieve this object, the present invention first applies an intonation layer (a ), a partially hollow base printing layer (b), a tone printing layer (c), and a conduit printing layer (d) are provided in this order.

In addition, as a method for manufacturing this decorative board, the present invention is to apply the above (a) to (d) on a releasable sheet in reverse 1 direction (that is, sequentially from (d) to (c), (b), A method is provided in which a transfer sheet having a transfer layer formed in (a) is laminated and adhered onto a wooden base material via an adhesive layer, and then a release sheet is peeled off and removed.

<Function> All of the four printing layers (a) to (d) according to the present invention have a punched portion. Therefore, there are differences depending on where these four printing layers overlap and where they do not, but FC)
The tone printing layer and (d) conduit printing layer are the same as in the conventional decorative one roll.

Therefore, in the areas where both the (a) pearl printing layer and (BL base printing layer) are not present, the wood base material can be seen through, and the original texture and depth of the wood base material can be utilized as is.

(al pearl printing layer is printed with an intonation layer, (b
) When there is no base printing layer, it is possible to emphasize areas of the base material with less texture, and a high-quality design can be obtained.

(b) In the area where the base printing layer is present, this color can be seen through, creating a pattern similar to natural wood.

The printing area, shape, etc. of each printing layer are determined depending on the desired type of natural wood, but as a result of the above, a decorative board with a luxurious design can be obtained.

<Description of Examples> The present invention will be described below with reference to the drawings. The drawings show examples of the present invention, with FIG. 1 being an explanatory cross-sectional view of a transfer sheet, and FIG. 2 being an explanatory cross-sectional view of the obtained decorative board.

In Fig. 1, the transfer sheet is a releasable sheet that becomes a hese, and a transfer layer (2) that is transferred to a wooden base material (3).
It is roughly divided into two layers. The transfer N (2) consists of a pearl print layer f8), a base print N (b), a tone print layer (c), and a conduit print layer (d), but in addition to these, a release sheet (1)
In order to adjust the peel strength of the transfer layer (2) and to protect the surface after producing the decorative board (after removing the release sheet), a layer is added between the release sheet (1) and the conduit printing layer (d). A protective layer can also be provided.

The above transfer sheet is placed on the wooden base material (3) with adhesive (4).
). The adhesive (4) is applied to the wood base material (3
) or the surface of the transfer layer (2) of the transfer sheet.

In addition, on the surface of the transfer layer (2), in order to strengthen the adhesive force with this adhesive (4), or the solvent of the adhesive (4) penetrates into each printing N (a) to (d). In order to prevent deformation of the image, an adhesion auxiliary layer (f) (not shown) may be provided in advance.

This adhesion aid (") is provided on the pearl ink layer (a). Any material can be used as the wood substrate (3), but it is preferable to use an inexpensive material such as raw plywood. . Apply adhesive (4) to the surface of the wooden base material (3).
If the adhesive (4) easily permeates into the wooden base material (3) of the cloth, the surface of the wooden base material (3) can be pretreated with a sealer treatment or the like.

As the release sheet (1), one that can be easily peeled off from the transfer layer (2) is used. For example, polyester, Volip I
-1 and synthetic resin sheets and items such as polyethylene, polyamide, polyamideimide, polycarbonate, polyvinyl chloride, cellulose acetate, nylon, vinylon, etc. Polypropylene, polyethylene, polyester, ethylene- A sheet formed by coating or adhering a vinyl acetate copolymer or the like as a release layer can be used.

Further, paper coated with urethane, aminoalkyd, silicone, polyamide, etc. may also be used.

The surface protective layer (e) is provided at a position in contact with the releasable sheet (1) for the purpose of protecting the surface of the decorative board after manufacturing.

The conduit printing layer (d) and the tone printing layer (c) may be printed in the same manner as before, but like the other printing layers (al and (b)),
It is desirable to print with an ink containing a vinyl chloride-i>acid vinyl copolymer as a binder.

The lower print layer (b) is partially unprinted (missing)
Printing is performed in the same manner as before, except for printing to have .

The pearl ink layer (Al is preferably printed with titanium-coated mica, but copper or zinc may also be used.

Printing is done using a tone plate with holes, that is, a plate with shading made from the target natural wood as a manuscript, with holes created in it. It is desirable that the voids be formed partially in the grain direction of the wood base material (3), but
There is no need to match the omission.

The adhesion auxiliary layer ([) is used to improve the adhesion between the transfer layer (2) and the adhesive (4), and to ensure that the container agent in the adhesive (4) adheres to each printed layer (2) of the transfer layer (2). In order to prevent deformation of a) to (d), it is provided as necessary.

The adhesive layer (4) is bonded or cured at room temperature at 10°C.
Anything that does not require higher temperatures can be used. For example, curable adhesives such as unsaturated polyester resins, epoxy resins, and urethane resins, vinyl acetate resins, ethylene-vinyl acetate copolymer resins, and acrylic-vinyl acetate copolymer resins can be used. It is desirable that the volume change is small during assimilation or curing, volatile components such as solvents are dissipated in a relatively short period of time, and that adhesive horns are provided in a state in which the volatile components are dissipated.

The adhesive (4) can be applied using a roll coater, reverse coater, flow coater, Curtan coater, air knife coater, gravure coater, spray coater, etc.
Can be applied to a wood base (O(3)) or a transfer sheet.

<Example> A mixed resin consisting of 75% polypropylene resin and 25% polyethylene resin was coated to a thickness of 20 μm by an extruder method on a smooth paper of 160 g/or to obtain a sub-form sheet.

Next, as a surface protective layer, a urethane-based (3) layer of 3μ thick
After applying a transparent ink mixed with vinyl chloride/vinyl acetate copolymer resin and acrylic resin, a conduit printing layer (d) and a tone printing layer (c) are sequentially applied.

A base printing layer (b) with gaps and a pearl ink layer (a) were printed. Note that these printed layers (a) to ((11) are
With a version created using the grain pattern of Izukimo oak as a manuscript,
It is printed.

On the other hand, 100 g/n of ethylene-vinyl acetate copolymer adhesive was applied to the surface of furan plywood with a thickness of 4 m/m.
? (Wet) After coating with a roll coater and dissipating the volatile components, the surfaces of the pearl ink layer (a) of the transfer sheet were overlapped while still having adhesive strength, and laminated by pressing.

After the adhesive had dried and hardened, only the %I type sheet was peeled off.

The resulting decorative board has the real texture and deep wood texture of a wood base material, and due to the effect of the pearl ink layer, the areas where the texture of the base material is weak are treated with IrM to improve the texture. It was designed to emphasize the natural wood of oak, making it more similar to natural oak wood.

<Effects of the Invention> As described above, according to the present invention, any wood material can be used as a material, and the pattern is the same as the intended one, yet it can be made from natural wood by emphasizing the texture. A very similar decorative board can be obtained.
