Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative sheet used for interiors of building materials, furniture, kitchens, etc., and more specifically to a decorative sheet having a genuine wood grain and a sense of depth and high designability. Is.

[0002]

2. Description of the Related Art There is a method of finely embossing a surface of a base material having a feeling of brightness such as a metallic layer or a pearl-containing layer in order to express a feeling of depth and a feeling of depth that a genuine wood grain design has. . This fine emboss is
A striped pattern consisting of a plurality of parallel straight or curved uneven striped patterns with fine intervals is defined as a unit pattern, and adjacent striped striped patterns are embossed patterns that are combined so that the striped directions of different striped patterns are different from each other. That is.

[0003]

By the way, in making an embossing plate for forming the above-mentioned fine embossing, first, the angles of several kinds of line patterns for changing the brightness depending on the viewing angle are set. The changed films are superposed to form one negative film, which is then turned into a positive and used as a film original to prepare a synthetic resin or metal embossing plate by a usual photoengraving method.

However, when a negative film is formed by laminating films having different parallel line angles as described above, the films do not completely overlap with each other due to thermal expansion and contraction of the films, and are displaced from each other. There will be a part where the line patterns overlap each other and a part where they separate from each other. This situation will be described with reference to FIG. 2. Pattern films A, B, and
When C is superposed on a negative film, a portion indicated by 10 is a portion separated at the time of superposing the films, and a space is formed between adjacent line patterns. Further, a portion indicated by 20 is a portion which is overlapped when the films are superposed, and adjacent line patterns are overlapped at their end portions. Further, the portion indicated by 30 is a portion where the adjacent line patterns do not separate from each other when the films are superposed and the edges do not overlap with each other, and the edges match exactly.

When an embossing plate is prepared using such a negative film, the portion indicated by 10 on the negative film has a concave shape on the embossing plate, the portion indicated by 20 has a convex shape on the embossing plate, and the portion indicated by 30. No unevenness occurs.

When the surface of the base material having a feeling of brightness is embossed with the embossing plate thus formed, the portion indicated by 20 on the negative film is formed into a concave shape, but the portion indicated by 10 on the negative film is formed. The portion is formed in a convex shape, and the convex portion is lifted up on the surface of the finished decorative sheet, resulting in a markedly poor design.

Therefore, the embossed shape on the surface of the decorative sheet is made so as not to be conspicuous even when the embossed shape is raised on the surface of the decorative sheet because the line pattern is not superposed when the negative film is produced. Although it was concealed with a gloss, luster, etc., there was a problem that the obtained designs were limited because there was a limit to the method that was made in time.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to solve the problems caused by the misalignment of line patterns when the negative film is formed, and to provide a decorative sheet having a high designability. The purpose is to provide.

[0009]

In order to achieve the above object, the decorative sheet of the present invention is provided with a plurality of parallel linear or curved concave-convex stripe patterns at fine intervals on the surface of a substrate having a feeling of brightness. The striped pattern consisting of is a unit pattern, and the striped patterns of adjacent striped patterns are combined so that the striped directions of the striped patterns are different from each other and there is no space between the striped patterns of adjacent striped patterns. It is characterized in that an uneven embossed pattern is formed.

In the decorative sheet of the present invention, the first transparent resin layer, the pattern printing layer and the second transparent resin layer are provided on the base material having the uneven embossed pattern formed on the surface thereof with an adhesive layer interposed therebetween. Are sequentially provided, a desired embossed pattern is formed on the surface thereof, wiping is performed, and a top coat layer is further provided thereon.

[0011]

In the decorative sheet of the present invention, when the negative film having an embossed pattern is formed, the adjacent line pattern patterns are scratched and made opaque with a colored opaque ink or the like, so that the line pattern patterns are separated from each other. It has the same effect as overlapping at the end, and there is no space between adjacent line patterns, so that the embossed shape of this part does not appear on the surface of the finished decorative sheet. It is possible to obtain various decorative sheets, and to express the texture and depth of a real wood grain design.

[0012]

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

FIG. 1 is a sectional view showing the construction of an embodiment of the decorative sheet of the present invention.

According to FIG. 1, a fine concavo-convex embossed pattern 2 is formed on the surface of a base material 1 having a sense of brightness, and a first transparent layer is formed on the base material 1 with an adhesive layer 3 interposed therebetween. Resin layer 4,
A pattern printing layer 5 and a second transparent resin layer 6 are provided in order, a desired embossed pattern is formed on the surface of the second transparent resin layer 6, and wiping with a wiping ink 7 is performed.
The top coat layer 8 is further provided thereon.

The fine embossed embossed pattern 2 is an embossed embossed pattern in which adjacent line patterns are combined so that the line angles thereof are different from each other, as shown in FIG. In addition, according to the present invention, when an embossing plate used for applying such embossing is produced, an adjacent portion line pattern generated during the production of a negative film and a line portion separated from each other (that is, a portion indicated by 10). ), The portion shown by 10 is scratched in an arbitrary line or pattern with a pen tip of a fountain pen and a colored opaque ink is put in the groove, or a colored opaque ink is formed. It is possible to form an opaque portion by a method such as directly applying a pattern or solid coating with, and to obtain the same effect as the overlapping portion of the pattern shown by 20. Therefore, by reversing such a negative film into a positive film, the open portion indicated by 10 can be made into the same state as the state in which the patterns of the portion indicated by 20 are overlapped. When embossing 2 is applied to the surface of the base material 1 by an embossing plate made using this positive film, it seems that a perforation in which the line pattern overlap is not successful 1
A concave emboss is imparted even in the 0 portion, and a decorative sheet in which the embossed shape of the 10 portion does not float on the surface of the finally obtained decorative sheet can be obtained.

In this way, on the surface of the base material 1 having a sense of brightness, there is a space between adjacent line patterns so that the line directions of adjacent line patterns are different from each other. The uneven embossed pattern is formed so as not to appear.

The above-mentioned substrate 1 having a sense of brightness is, for example, a metallic layer or a pearl-containing layer, and specific examples thereof include scaly aluminum particles and organic or inorganic fine particles (polyethylene beads, glass beads, etc.). ) Or an emulsion type acrylic resin containing a pearl pigment coated on flame-retardant paper, a laminate of a polyethylene terephthalate film and a polyvinyl chloride film vapor-deposited on aluminum on the flame-retardant paper.

As the adhesive layer 3, a polyurethane adhesive or the like can be used.

Vinyl chloride resin or the like can be used for the first transparent resin layer 4 and the second transparent resin layer 6. The thickness of this transparent resin layer is arbitrary, but is usually 0.0
About 6 to 0.2 m / m is desirable.

The pattern printing layer 5 can be formed by a known printing method such as gravure printing, but the position where the pattern printing layer 5 is formed is not limited to that shown in FIG. For example, it may be formed under the first transparent resin layer 4 (in this case, one of the first and second transparent resin layers 4 and 6 may be omitted).

A desired embossed pattern can be formed on the surface of the second transparent resin layer 6 to improve the design, and wiping can be performed. In particular, it is desirable that the embossed pattern in this case be in synchronization with the pattern of the pattern printing layer 5. Explaining an example of a wiping method, first, a wiping ink (coloring paint) 7 is applied to the entire surface of the second transparent resin layer 6, and the surface of the second transparent resin layer 6 is covered with a squeegee, a barrel or a dry cloth before the wiping ink 7 solidifies. The wiping ink 7 on the convex portions is removed, and the remaining wiping ink 7 on the concave portions is dried and solidified.

For the purpose of protecting the surface of the decorative sheet, it is desirable to provide the top coat layer 8 on the top.
Generally, it is preferable to use urethane resin or the like for the top coat layer 8.

[0023]

As described above in detail, the decorative sheet of the present invention has a striped pattern composed of a plurality of parallel linear or curved uneven striped patterns with fine intervals on the surface of the substrate having a feeling of brightness. Is a unit pattern, and adjacent unit striped patterns are embossed by embossing so that the strip directions of the same striped patterns are different from each other and there is no space between the adjacent unit striped patterns. Since the pattern is formed, there is no problem that the embossed shape of the base material surface partially rises on the surface of the decorative sheet, and it is possible to fully express the feeling of texture and depth that a real wood grain design has, A decorative sheet with a high design property can be obtained.

Further, the decorative sheet of the present invention, in particular, has a first transparent resin layer, a pattern printing layer, and a second transparent layer on the base material having the uneven embossed pattern formed on the surface thereof via an adhesive layer. A resin sheet is sequentially provided, a desired embossed pattern is formed on the surface of the resin layer, wiping is performed, and a top coat layer is further provided on the resin layer, whereby a decorative sheet having a higher design property can be obtained.
