る。2. Description of the Related Art In recent years, there is known an embossed decorative plate that imitates or faithfully reproduces the shape of a conduit groove on a wood surface, which has been reviewed as a substitute for natural wood, which is becoming difficult to obtain due to exhaustion. In particular, in the field of polyester decorative boards using unsaturated polyester resins, many products and attempts have been made so far due to the difference in the embossing method, but when roughly classified, (a) from natural wood manuscripts,
An embossing type (film type) that faithfully molds the uneven shape of the surface such as conduit grooves using a curable resin with good mold release
Or (b) using an embossing roll obtained by electroforming such as (b), or (c)
A natural wood manuscript made of a thermoplastic film or the like, or an embossed die (film form) formed by inverting and casting from a mother die by a hot press or a high frequency press, or (d) It is widely known that an arbitrary plate obtained by making a plate based on a positive or negative manuscript of the natural wood conduit part and using an embossed type (film form) of a raised printing method by gravure printing or silk screen printing is widely known. Has been.
Among the above-mentioned four kinds of giving methods, (a),
With regard to (b) and (c), it is possible to realistically reproduce the shape of the conduit groove of natural wood due to its technical characteristics.

ことにある。However, in order to reproduce this realistic conduit groove shape, the thickness of the emboss-forming resin layer of the decorative plate tends to be large, and any synthetic resin widely used at present should be used. However, it is an undeniable fact that, when the decorative plate is cut, the resin layer is cracked or chipped, and the secondary processability is lowered, and the cost is increased due to an increase in the amount of resin used. Therefore, the present invention has been made in view of these problems, and an object thereof is to provide a wood grain embossed decorative board having a more stable, inexpensive, and realistic embossment of a conduit groove of natural wood.

It is not necessary to reproduce the conduit depth of 0) 100% of the natural wood conduit depth, and if it is reproduced to about 10-80% from the surface side of the natural wood surface conduit depth, a design-satisfactory appearance is obtained. Therefore, even if the thickness of the synthetic resin layer (6) is about 50 to 700 μm, a design effect very similar to the shape of the conduit groove on the surface of natural wood and a significant saving of the resin layer are possible. For example, FIG. 3 (a) is an embossed type in which the surface of a natural wood is inverted / cast to reproduce almost 100% of its conduit groove, and FIG. 3 (b) is obtained by inverting / casting the surface of a natural wood. The depth of the embossed conduit is adjusted to about 50% of that of natural wood. Figure 3 (c) shows the embossed conduit depth obtained by inverting and casting the surface of natural wood. It was adjusted to about 10%. The design effect (similarity to natural wood) of the embossed decorative board that is rolled and hardened using these three types of embossing dies.
Shows no significant difference in any of FIGS. 3 (a), (b), and (c). However, the thickness of the resin layer (6) required at this time is as shown in FIG. 3 (a)>(b)> (c), and in the case of FIGS. 3 (b) and 3 (c), its designability is secured. The resin layer (6) can be largely saved as it is.

０μｍに削減することが可能となった。EFFECTS OF THE INVENTION The wood grain embossing board according to the present invention forms a wood grain emboss by using an embossing type in which the opening shape of the conduit portion on the surface of natural wood is formed in reverse, or an embossing type having a conduit groove shape similar to this. In doing so, the obtained embossed mold is applied to the natural wood surface from the surface side of the groove depth of the conduit for 10 to 80
%, It is possible to reduce the thickness of the transparent or translucent resin layer that is embossed without impairing the realistic expression of the wood grain conduit, giving embossing to the wood grain embossed decorative board. Resin layer thickness of 50 to 70
It became possible to reduce to 0 μm.
