2. Description of the Related Art As a conventional decorative board of this type, for example, titanium paper or the like having a pattern layer formed on the upper surface thereof with a large number of concave portions corresponding to a desired decorative pattern, for example, a pattern of wood grain or the like is used. The embossed base paper is laminated on a substrate such as a particle board or a plywood by an adhesive through a roll press, and a decorative board made of an embossed base paper having the above-mentioned pattern layer and an unsaturated polyester resin applied to the entire upper surface of the embossed base paper. Can be mentioned.

The embossed base paper is formed of a pulp material which is a swelling material, and the adhesive used is an emulsion type in which a resin is dispersed in water. Therefore, the moisture penetrates into the embossed base paper. As a result, the recesses formed on the embossed base paper are caused to lose their shape, resulting in a design problem in that a desired uneven decorative pattern cannot be obtained.

[0004]

SUMMARY OF THE INVENTION Therefore, the technical problem to be solved by the present invention is that when embossed base paper in which recesses are formed according to a desired pattern is laminated on a substrate through an adhesive, This is to prevent the recess from losing its shape.

[0005]

In order to solve the above problems, the present invention provides a decorative board having the following structure.

That is, in this decorative plate, a thermosetting unsaturated polyester resin as an adhesive layer is applied onto a substrate,
An embossed decorative base paper on which a large number of concave portions corresponding to a desired decorative pattern are formed and a pattern layer is formed on the upper surface is laminated on the unsaturated polyester resin layer, and the entire upper surface of the embossed decorative base paper having the pattern layer is unsaturated. It is formed by applying a polyester resin and curing it integrally.

In the above structure, a glitter ink layer may be laminated between the picture layer and the embossed decorative base paper, and the glitter ink layer is formed on the upper surface of the embossed decorative base paper and the recesses. May be laminated on the entire surface including. In this case, gold ink or silver ink is preferably used as the material for forming the glitter ink layer.

According to the above constitution, since the unsaturated polyester resin liquid does not contain water, when the polyester resin liquid is used as the adhesive, when the resin liquid penetrates into the embossed decorative base paper, the liquid Therefore, the embossed decorative base paper is not swollen. Therefore, the depressions formed on the embossed decorative base paper are prevented from losing their shape, and a decorative design faithful to a desired embossed decorative pattern can be realized. Further, since the embossed decorative base paper has permeability to unsaturated polyester resin as described above, the embossed decorative base paper laminated on the substrate through this unsaturated polyester resin was integrally heat-cured. Occasionally, the unsaturated polyester resin that has penetrated into the embossed decorative base paper is also cured at the same time, so that the adhesion of the embossed decorative base paper to the substrate can be improved.

Embodiments of the present invention will be described in detail below with reference to FIGS.

First, a first embodiment will be described with reference to FIG.

FIG. 1 is a sectional view of an essential part showing the steps of manufacturing a decorative board according to this embodiment, in which (III) is
The finished product of the decorative board is shown.

In FIG. 1 (III), 10 is an embossed decorative base paper, and 6 is a pattern layer printed on the embossed decorative base paper. As shown in the figure, a concave portion 16 is formed on the upper surface of the embossed decorative base paper 10 according to a desired decorative pattern. For example, when it is desired to express a grain of wood, a large number of concave portions 16 corresponding to the conduits of the grain of wood are formed at predetermined positions on the upper surface of the embossed decorative base paper 10. Further, the pattern layer 6 is formed on the upper surface of the embossed decorative base paper 10.

Further, as shown by (III), the embossed decorative base paper 10 on which the pattern layer 6 is laminated is laminated on the substrate 14 with the unsaturated polyester resin layer 12 interposed therebetween.

Further, the unsaturated polyester resin layer 4 is laminated on the entire upper surface of the embossed decorative base paper 10 on which the pattern layer 6 is laminated, whereby the entire upper surface of the embossed decorative base paper 10 having the pattern layer 6 is protected. To be done.

The decorative board having the above structure is manufactured by the following manufacturing process.

That is, as shown by (I), first, the pattern layer 6 is formed by printing on the embossed decorative base paper in which the recesses 16 are formed according to the desired pattern.

On the other hand, the unsaturated polyester resin 12 is roll-coated on the substrate 14. Then, as shown in (II), the embossed decorative base paper 10 on which the pattern layer 6 is formed is laminated.

Then, as shown in (III), the unsaturated polyester resin 4 is applied on the entire upper surface of the embossed decorative base paper 10 having the pattern layer 6, and the polyester film 2 as a gas barrier layer is further laid on the unsaturated polyester resin 4. To match.
Since the unsaturated polyester resin liquid has a property that the curing speed is slowed down by contacting with oxygen in the atmosphere when it is thermally cured, the unsaturated polyester resin liquid can be treated by stacking the polyester film 2 thereon as described above. The liquid polyester resin layer 4 is kept out of contact with the outside air.

Then, the laminate is heated and cured. At this time, the unsaturated polyester resin 4 applied to the entire upper surface of the embossed decorative base paper 10 having the pattern layer 6 by the polyester film 2 is blocked from contact with the outside air, and the curing is accelerated. After the curing is completed, the polyester film 2 is removed from the unsaturated polyester resin layer 4 to obtain a finished product of the present decorative board.

Next, the second embodiment will be described with reference to FIG. 2, and the third embodiment will be described with reference to FIG.
