The front plate and deck of furniture are decorated with a three-dimensional pattern to make it appear as if it is carved. The height difference of the unevenness on the most surface side is 4-5 mm. It was a big one. The cross-sectional structure of this conventional laminated plate has a sturdy substrate 1 having a thickness of 12 mm or more, a thin decorative plate 2 composed of a single plate adhered to the surface 1a of the substrate 1, and a surface of the decorative plate 2. The resin layer 3 is provided so as to be in a surface-covered state or an impregnated state with respect to the entire top and the wall thickness and the surface portion of the substrate 1. The decorative board 2 was not necessary when the surface properties of the substrate 1 were satisfactory from the viewpoint of appearance.

That is, one thermosetting resin has the function of maintaining the uneven shape that is uneven on the most surface side of the conventional laminate and developing moisture resistance after curing, and the other thermoplastic resin is The decorative plate 2 and the substrate 1 have a function to protect the surface portions of the decorative plate 2 and the substrate 1 from being cracked and to easily deform them into an uneven shape. As described above, the resin layer 3 is formed of the thermosetting resin and the thermoplastic resin. Therefore, when the unevenness is formed on the resin layer 3, it is necessary to provide the uneven shape. Was heated at the same time as the embossing, and this embossed state was maintained for 2 to 3 minutes until the thermosetting resin was cured.

あった。(Problems to be Solved by the Invention) First, in the conventional laminated board, in forming the resin layer 3, the entire thickness of the decorative board 2 and the surface portion of the substrate 1 are impregnated with a thermoplastic resin. Secondly, the substrate 1 is thick (12 mm) due to the two points that the substrate 1 has a required strength for increasing the height difference of the unevenness.
I had to do this). Therefore, the conventional laminated board is usually used for high-class furniture furniture and the like, and is not versatile for other purposes. This is because, when the conventional laminated board is used for things other than high-end furniture furniture, the ratio of the conventional laminated board to the manufacturing cost of the entire product may be too high, and the entire product is taken into consideration. Even in the case, it was not possible to make a fine balance in the work with other parts. Moreover, in the conventional laminated plate, the thermoplastic resin has to be impregnated not only to the entire thickness of the decorative plate 2 but also to a predetermined depth of the surface portion of the substrate 1, so that a mold for imparting an uneven shape is formed. The simultaneous heating of the push had to be maintained for as long as 2-3 minutes. As a matter of course, during this heating, various work to be refrained from after the heating is delayed, so that the conventional laminated plate is also inferior in manufacturing efficiency.

なる。(Operation) The base layer used in the method of the present invention is to form the basis of a laminated plate, which is similar to the conventional laminated substrate.
The wall thickness covers a wide range from thin to thick. In the base layer used in the method of the present invention, the biggest reason why a thin one can be used is the stress dispersion layer adhered on the surface of the base layer. That is,
This is because the stress-dispersing layer diffuses the pressing force of the mold for imparting the uneven shape over the entire surface of the base layer and prevents the decorative layer and the base layer from being cracked due to stress concentration. Further, due to this, in the method of the present invention, whether the surface coating layer made of the synthetic resin material formed on the surface of the decorative layer is impregnated into the decorative layer or the base layer is not so important. Become. Therefore, in the method of the present invention, the embossing and the simultaneous heating for imparting the uneven shape may be maintained for an extremely short time. And
When the method of the present invention as described above is carried out, the thickness of the base layer is 10 mm.
Even if it has the following thickness, it can be used without any trouble. That is, the thickness of the base layer
In the laminated board of the present invention whose thickness is limited to 10 mm or less, the overall thickness of the laminated board can be reduced, so that it is not limited to a furniture-oriented furniture intended for high-class purposes.

However, the material of the base layer 4 used in the method of the present invention includes board materials such as gypsum board, particle board, wood board, plywood, fiber board, solid wood, metal board, synthetic resin board, paper material or cloth material. Any material having a smooth surface (not necessarily flat) such as a synthetic plate may be used. Although not shown in the drawing, like a veneer plate is attached to the front and back surfaces of the plate-shaped object as a framework,
A so-called flash material may be used as the base layer 4. Therefore, the base layer 4 can be applied in a wide range from a thin one having a thickness of less than 10 mm to a thick one (without limitation).

多の優れた利点を有している。"Effects of the Invention" As is apparent from the above description, according to the method for manufacturing a laminate having an uneven surface according to the present invention, the thickness of the base layer is applied in a wide range from thin to thick. In addition, the unevenness provided on the outermost surface side can be arbitrarily formed from a large unevenness to a small unevenness. Therefore, the versatility of the obtained laminate is endlessly expanded. In addition, since it is not necessary to impregnate the decorative layer and the base layer with the synthetic resin material for forming the surface coating layer, the conventional embossing maintenance time required for that is not required, and the amount of the synthetic resin material used is also reduced. Can be reduced. Therefore, the manufacturing efficiency can be increased and the manufacturing cost can be reduced. On the other hand, according to the uneven laminate using the thin base layer according to the present invention, not only the overall wall thickness can be reduced, but also the unevenness provided on the most surface side can have a small undulation, so that the furniture Even if the product is used for a product other than a product having a high-grade orientation, there is no fear that the fine balance of the work will give an uncomfortable feeling. Therefore, it has a number of excellent advantages such as being able to be effectively used as a unit furniture relatively popular with the general public and a wall plate having a large area.
