Description

  The present invention relates to a decorative material, and in particular, to a float-grained decorative material.

  Natural wood processed products are widely used for building materials, joinery, construction materials and furniture. However, there is a limit to high-quality natural wood resources, and instead of exhausting, a decorative material for imparting a wood-grained design to the surfaces of building materials and furniture may be used instead. In order to obtain a visual appearance reproduction effect close to that of real wood, the wood-tone decorative material has an annual ring formed of a spring material (early material) portion and an autumn material (late material) portion. In order to enhance the appearance and feel of the design, such an annual ring is a process that raises the autumn material part of the annual ring by polishing the surface of the wood (so-called “floating” process). A spring material portion is expressed by gravure printing, and an autumn material portion is expressed by gravure printing, intaglio printing, or silk screen printing (for example, see Patent Document 1).

However, in the wood-tone decorative material proposed in Patent Document 1, the effect of reproducing the visual design appearance and tactile sensation of floating design is insufficient, and the tactile sensation is particularly insufficient. It was difficult to say that it had a close design.
Therefore, the grain of the spring wood part is printed on the resin base material by gravure printing, and the embossed plate made from the natural wood floating board surface by electrocasting is used to shape the convex part of the autumn wood part. Toned decorative materials have been proposed (see, for example, Patent Document 2).

To collect information on optical density P (X, Y) at each position coordinate (X, Y) in the plane of the surface of the wood board. As a result, an optical density P (X, Y) = mH (X, Y) corresponding to the height H (X, Y) at each position coordinate (X, Y) in the plane of the surface of the wood board is obtained. Here, m is an appropriate coefficient. Next, it is converted into an optical density P (θ, Z) at coordinates (θ, Z) on the metal cylinder used as the material of the embossed plate.
(3) Next, the cylindrical optical density P (θ, Z) is converted into cylindrical height information H (θ, Z) = nP (θ, Z). Here, n is an appropriate coefficient.
(4) Next, while rotating the metal cylinder around its axis, the surface of the cylinder is scanned while being irradiated with the engraving laser beam, and the irradiation light amount E of the laser beam at the cylindrical coordinates (θ, Z) is determined. Control is performed so that the irradiation light amount E = kH (θ, Z) corresponding to the obtained height H (θ, Z). Here, k is an appropriate coefficient. As a result, a concavo-convex shape having a depth D (θ, Z) = klH (θ, Z) corresponding to the amount of irradiation light is engraved on the surface of the metal cylinder. Here, l is an appropriate coefficient.
(5) By going through the above steps, the depth D (θ, Z) = klH (θ, Z) corresponding to the height H (X, Y) of the surface of the floating wooden plate of the original on the metal cylinder surface An embossed plate having an uneven shape of depth is obtained.
Using the laser embossing plate thus obtained, embossing on one surface of the substrate 1, that is, shaping by embossing of the embossing plate, is performed on one surface side of the substrate 1. It is possible to give a dense uneven shape composed of the first convex portion 2 and the second convex portion 3 specified by the invention, and the production time is shorter and cheaper than the embossed plate by electroforming or the like.
