Description

[Detailed Description of the Invention] [Industrial Application Field] The visitor's invention relates to a decorative material used as a surface material for furniture, furnishings, wall materials, etc., and is a decorative material that has a three-dimensional wood grain similar to natural wood. It is a decorative material with a pattern, which has a gloss matte effect.

[Prior Art] Decorative materials with printed patterns similar to the grain patterns of natural wood are widely used as surface materials for furniture, furnishings, wall materials, etc. A glossy transparent resin coating layer is formed on the entire surface of the decorative sheet base paper obtained by applying the pattern, and then a matte printing layer corresponding to the wood grain conduit grooves is coated on the transparent resin coating layer. For a decorative sheet partially formed on a resin coat layer or a decorative sheet base paper obtained by adding a wood grain printing pattern to a decorative base paper, a portion corresponding to the wood grain conduit groove portion is placed on the wood grain printed pattern surface. The matte printing layer and the glossy printing layer forming a part corresponding to the non-conduit groove part which is a part other than the matte printing layer, and the height of the glossy printing layer corresponding to the non-conduit groove part is the wood grain conduit groove part. A decorative sheet (Japanese Patent Publication No. 53-331), which is formed to be higher than the height of the corresponding matte printing layer, is used.

[Problems to be Solved by the Invention] By the way, all of the conventional decorative sheets mentioned above have the following problems:
This is because the degree of matteness expressed in the wood grain conduit groove pattern portion, which has a color and outline shape similar to the wood grain conduit grooves, is determined only by the degree of matteness that can be expressed by the aforementioned matte printing layer. However, this method has the disadvantage that it is not possible to express a conduit groove pattern with a high degree of matte on the surface of the decorative sheet.

In addition, in the case of the former decorative sheet in which a matte printed layer corresponding to the wood grain conduit grooves is partially formed on the transparent resin coat layer, the conduit groove pattern made of matte ink forms the uppermost surface of the decorative sheet. Therefore, the conduit groove pattern does not give an impression of resembling the grain pattern of natural wood, which has concave portions, and furthermore, the difference between the matte printed layer and the glossy pattern layer of the latter. In the case of a decorative sheet having a negative/positive printed layer, when a printing misregistration occurs in the negative/positive printed layer, the surface physical properties of the exposed base portion are poor, and moreover, the exposure of the base portion causes a sense of discomfort. However, it has disadvantages such as reducing the design effect.

On the other hand, in the inventions of wood brushes 1 and 2, conduit groove pattern portions with a high degree of matteness and concave portions are exposed on the surface of the decorative material, and are partially formed. It is possible to provide a decorative material that does not give an unnatural feeling even if there is some misalignment of printing registration in the printed layer.
