同調エンボス化粧板の製造方法に関するものである。[Detailed Description of the Invention] [Detailed Description of the Invention] The present invention uses films, metal foils, papers, etc., which have a printed pattern for transfer on one side and convex portions for embossing on the other side and are synchronized and used as a release sheet. The present invention relates to a method of manufacturing a tone-embossed decorative board characterized by:

造方法を提供する。The chemical embossing method involves foaming the concave areas and scraping off the foamed areas, or weakening the strength of the printing ink in the concave areas to physically peel them off, or further adjusting the hardening state to match the design. By changing it, uneven steps were created. Embossed decorative boards obtained by these chemical embossing methods had shallow recesses and were extremely poor in physical properties such as stain resistance.
Furthermore, in the method of using a patterned board with concaves and convexes that are synchronized with the design of the decorative board, the surface properties are good, but it is extremely difficult to obtain a precisely matched embossed decorative board, and the meaning of synchronization has diminished. The present invention overcomes these conventional drawbacks and provides a method for producing tone embossed decorative boards and decorative sheets without impairing surface properties.

以下に本発明を詳細に説明する。The present invention will be explained in detail below.

レンをラミネートする必要がある。The release sheet 1 used in the present invention can withstand temperatures during decorative board molding, generally 120 to 150°C in the case of melamine decorative boards and polyester decorative boards, and also has mold releasability from decorative boards. In the case of synthetic resin films, there are polyester and polypropylene films, and in the case of metal foils, there are aluminum and copper foils.For paper, there are

インクにより転写柄３を印刷する。If the thickness of the sheet 1 is thin, wrinkles will occur during handling, and if it is thick, the effect of the convex portions 2 for embossing will be lost, so depending on the type of release sheet 1, a thickness of 10 to 200μ is appropriate. It is. A transfer pattern 3 is printed on one side of such a release sheet 1 using transfer ink.

る。In this case, there are no restrictions on the type of ink or the printing method, and an ink that easily penetrates the surface resin of the decorative board is used for printing, such as a silk screen printing method or a gravure printing method. On the other side of the release sheet 1, a hard embossing convex portion 2 with a pattern that is in sync with the transfer pattern 3 is formed.

紙７（チタン紙）、台紙層８との間に挟む。The convex portion 2 is formed of a synthetic resin such as polyurethane, epoxy, polyester, or cellulose acetate containing an inorganic substance such as titanium white, aluminum oxide, glass beads, or metal powder. There is no particular restriction on the forming method, but it is preferable to use the same printing method as for the transfer pattern.As described above, the transfer sheet 1 with the transfer pattern 3 printed on one side and the convex portions 2 formed on the other side is As shown in FIG. 2, it is sandwiched between the backing board 4 and the decorative board components 5, such as an overlay paper 6, a patterned paper 7 (titanium paper), and a mount layer 8.

(Fig.), the hard convex portion 2 bites into the decorative laminate component 5, and the component 5 is recessed. At the same time, the transferred pattern 3 is transferred to the overlay paper 6, and an embossed decorative board 10 in which the transferred pattern and the recesses 9 are aligned is completed. In the present invention, it is also possible to print a pattern on the pattern paper 7 of the decorative board structure 5 in advance and combine it with the transfer pattern 3. The printed portion of the tuned embossed decorative board 10 of the present invention has excellent stain resistance due to the concave portions 9.
In practical terms, it has physical properties that are not much different from ordinary decorative boards. In particular, when surface properties are required, the transfer printing pattern 3 can be printed on the transfer printing surface of the release sheet 1 coated with a surface resin for decorative board in advance. In this case, there is a resin layer on the surface of the obtained tuned embossed decorative board 10, and the surface physical properties are more excellent. Next, the present invention will be explained by examples. Example 1 An abstract pattern for transfer is screen printed on one side of a 25μ matte polypropylene film using heat-resistant melamine decorative ink, and on the other side, a urethane resin containing 70% titanium white is printed at the same position as the transfer pattern. A pattern for imprinting with a thickness of 10 μm was printed using a silk screen.
