Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative board used for surface materials such as wall boards and door boards of buildings or furniture.

This type of surface layer is often made of a decorative laminate with a surface appearance similar to that of a wood board. By applying a colored paint color to give the wood grain a three-dimensional effect, and by performing an embossing process similar to a conduit, etc.
It has an uneven shape similar to a conduit (crested), and the synergistic effect of the depth of the color and the unevenness of the crested surface (shigitsuke) skillfully gives it the luxurious feel of a wooden board.

By the way, in this type of wood-grain decorative board, when the surface of the decorative board is coated with transparent plastic for the purpose of strengthening its durability, the unevenness of the conduit engas is less likely to occur during the coating process. Due to the smoothing caused by heating and the fact that the surface of the coating becomes a smooth surface, there is a problem that the three-dimensional effect of the decorative board is significantly reduced. , you can only see the depth of the color through the transparent layer of the coating.
This is because the uneven appearance of the emboss disappears.

The present invention has been made to solve these problems, and an object of the present invention is to add transparent plastic to the surface of the plate without impairing the three-dimensional effect of the decorative plate with crests such as wood grain. To provide a decorative board on which a layer is formed (/C).

As a means for achieving the object, the decorative board of the present invention is a decorative board consisting of a smooth transparent plate surface layer, an intermediate decorative printed layer, and a printed base layer, in which a metal pigment or a nocool pigment is added to the printed base layer. It is characterized in that it is completely blended and that powder-like irregularities are integrally formed on the back surface of the surface layer from the printing base layer side as a bonded shape.

In general, the decorative board of the present invention is composed of a smooth transparent board surface layer, an intermediate decorative print layer, and a printed base layer. It is characterized in that it has a translucent layer containing a pearl pigment, and powder-like irregularities are integrally formed on the back surface of the surface layer from the printing base layer side in the form of a bond.

Furthermore, in the decorative board of the present invention, the decorative board is composed of a smooth transparent plate surface layer, a decorative printing layer, and a printing base J1', A layer, in which the decorative printing layer is coated with a metal pigment or /Yarl pigment. It is characterized in that it is composed of mixed and scratched printing, and that powder-like irregularities are integrally formed on the back surface of the surface layer from the printed nord layer side.

Hereinafter, the present invention will be explained based on Examples.

1st Embodiment (See Figures 1A and B 11 (1) The decorative board 1 of this embodiment has a surface layer 2 made of a flat 11t transparent plus deck board, and a metal face (dou or / e-le pigment). or mixed printing group jl'A' II 3' Table 1fii I':
* 2 (Printed base 4' with decorative printing Jvj7 such as wood grain on the surface of 11!1 is completely formed by polymerization with A layer 3.Furthermore, the printed base material layer 3 has a surface from the back side. A powder-like unevenness 4 similar to that of a wood-grained conduit tube is formed integrally across the entire surface, and as a result, the printing base material layer 3 is integrally bitten into the back surface of the surface layer 2. Due to this biting, the printing base material The metal pigment or pearl pigment mixed in the material 3 becomes visible through the printing layer 7, and a difference in gloss appears, so that a decorative board 1 with a three-dimensional effect is obtained.When manufacturing the decorative board 1 according to this example, As shown in Figure 2,
The surface layer 2 made of the above-mentioned plastic plate and the printing base material 3 on which the above-mentioned decorative printing layer 7 has been applied are coated with a smooth roll 5 and an embossing roll 6.
Place it on the back side of the sheet and press it together so that they overlap together.

Alternatively, as shown in FIG. 3, the surface layer 2 and the printing base material layer are pressed together so that the embossed mold 9 is positioned on the back side of the decorative printing layer 7 to overlap them.

The decorative board 11 of this embodiment is formed by the polymerization of a surface layer 12 made of a smooth transparent glass board and a printed capture material 13 having a decorative printed layer 17 such as wood grain on the surface on the surface layer J2 side. A translucent layer 20 made of a plastic film containing a small amount of metal pigment and/or ol pigment is formed on this polymerization interface. Further, the printing base material layer is integrally molded with powder-like irregularities 14 similar to wood grain conduits from the back surface to the front surface, so that the translucent layer 20 is integrally formed on the back surface of the surface layer 12. It has a biting shape. In addition, as described above, translucent Ni 20 is made by using ink or paint containing a small amount of metal pigment or pearl pigment in the decorative printing layer 1 instead of the plastic film.
It may be applied on top of 7.

In this way, since the decorative printing layer is seen through the semi-transparent layer containing a small amount of metal pigment or [Zero pigment], there is a difference in the smooth surface and the part where the diaphragm-like unevenness has been formed, and it is extremely three-dimensional. A decorative board with a nice feel can be obtained.

Third Embodiment This embodiment is characterized in that the metal pigment or pearl pigment in the first embodiment is mixed into the decorative printing layer by blending it into the printing ink, and the pigment is mixed into the decorative printing layer from the back side of the printing base layer. Powder-like irregularities resembling conduits, such as wood grain, are integrally formed on the surface, and as a result, the printing base material layer bites into the back surface of the surface layer.

By the way, the decorative boards of these examples have a very three-dimensional effect despite having a smooth surface, and the surface layer (usually has a thickness of 0.5 to 5.0 m, preferably 1.0 to 3.0 mm)
), the durability of the decorative board is significantly improved. As the surface layer, a transparent plastic plate such as a hard PVC plate, an acrylic plate, a polycarbonate plate, etc. can be used.

As the printing base layer, a plastic film or sheet with a high printing layer can be used, and suitable plastics include:
There are hard and semi-hard vinyl chloride resins, ABS resins, etc.

Metal pigments and pearl pigments that can be used in the present invention include brass, aluminum, mica, and the like.

In each of the above embodiments, the decorative printing layer may have a wood grain pattern, a leather pattern, a stone pattern, a metal corrosion pattern, or a color. In addition to the shape of a conduit, the concavo-convex irregularities can be formed into an appropriate pattern such as a leather-bound pattern or a geometric pattern.

As described above, according to the decorative board according to the present invention, a decorative board with excellent three-dimensional appearance and durability can be obtained, which has the effect of improving the marketability of the decorative board.
