Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-dimensional decorative board that exhibits excellent beauty with a rich three-dimensional effect.

Conventionally, three-dimensional decorative boards include embossed decorative boards in which a concave pattern is formed by pressing an embossing roll or template onto the surface of a substrate, and screen-printed decorative boards in which a raised pattern is formed by screen printing on the surface of a substrate. .

However, in the embossed decorative board, if the embossed recesses are deepened, cracks will occur on the substrate surface, so there is a certain limit to the depth of the embossed recesses. In addition, screen printed decorative boards are
There is a certain limit to the thickness of a printed pattern because a thicker printed pattern requires a large amount of paint or ink, which increases material costs. Therefore, it cannot be said that these decorative boards sufficiently exhibit an excellent aesthetic appearance rich in three-dimensional effect. The purpose of the present invention is to
To provide a three-dimensional decorative board exhibiting an excellent aesthetic appearance richer in three-dimensional effect than an embossed decorative board or a screen-printed decorative board. The present invention is a clever combination of an embossed decorative board and a screen-printed decorative board, in which a recessed pattern is formed on the surface of the substrate, and a raised pattern is formed along the edges of this recessed pattern. This is a three-dimensional decorative board characterized by having three levels of height: a concave pattern portion, a substrate surface portion, and a raised pattern portion.

Since the three-dimensional decorative board of the present invention has a raised pattern along the edge of the recessed pattern, a large step is formed between the recessed pattern and the raised pattern, which is better than conventional embossed decorative board or screen-printed decorative board. It exhibits an excellent sense of beauty with a rich three-dimensional effect.

Furthermore, since three levels of height are formed on the surface of the decorative board, including the concave pattern portion, the substrate surface portion, and the raised pattern portion, the decorative board exhibits a varied and tasteful aesthetic appearance. Next, examples of the present invention will be described. The three-dimensional decorative board of this example, a part of which is shown in FIGS. 1 and 2, is made by applying adhesive to the surface of a soft fiberboard 1, and rolling an embossing roller on the surface with a thin decorative paper 2 interposed therebetween. At the same time as pasting the paper, a fine uneven pattern is formed, the adhesive is dried to form a substrate 3, water is sprinkled on the surface of this substrate 3 to which the decorative paper 2 is pasted, and the surface is heated to increase its flexibility. The embossed templates are pressed against each other to form linear dent patterns 4 and circular dent patterns 6 expressing something like flower petals, and acrylic resin is applied to the surface of the substrate 3 on which the dent patterns 4 and 6 have been formed. Silk screen printing is performed using a solution-based paint or ink to print along the linear raised pattern 8 along one side edge 5 of the linear recessed pattern 4 and the peripheral edge □ of the circular recessed pattern 6. An annular raised pattern 9 is formed.

In addition, in the three-dimensional decorative board of this example, the depth of the linear and circular concave patterns 4 and 6 is about 0.3 u, the width of the linear concave pattern 4 is about 10 u, and circular raised pattern 8
, 9 has a thickness of about 0.3IE, and both raised patterns 8,
The width of the pattern 9 is about 10n, and a slight interval is provided between the linear concave pattern 4 and the linear raised pattern 8 and between the circular concave pattern 6 and the annular raised pattern 9, respectively.

In the three-dimensional decorative board of this example, the raised patterns 8 and 9 are formed along the edges 5 and T of the recessed patterns 4 and 6, so a large step is formed between the recessed pattern and the raised pattern, which is different from the conventional embossed pattern. It exhibits an excellent aesthetic appearance with a richer three-dimensional effect than decorative laminates or screen-printed decorative laminates.

In addition, three levels of height are formed on the surface of the decorative board, including the concave patterns 4 and 6, the surface of the substrate 3, and the raised patterns 8 and 9, giving it a varied and tasteful aesthetic appearance.
