【発明の詳細な説明】 (産業上の利用分野) 本発明は凹凸模様を有する金属化粧板の製造方法に関す
る。TECHNICAL FIELD The present invention relates to a method for producing a decorative metal plate having an uneven pattern.
(従来の技術) 転写法により各種プラスチック製品や金属製品の表面に
絵付けを行うことは、近年盛んに用いられている。この
ように、転写法により絵付けを行った場合、絵柄の表面
に保護層を設けることにより表面強度を向上させている
のが一般的である。しかし、この保護層を絵柄上に設け
ると表面の艶が均一で単調なものとなってしまうという
欠点があった。(Prior Art) Painting on the surface of various plastic products and metal products by a transfer method has been actively used in recent years. In this way, when painting is performed by the transfer method, the surface strength is generally improved by providing a protective layer on the surface of the pattern. However, when this protective layer is provided on the pattern, there is a drawback that the surface gloss becomes uniform and monotonous.
例えば絵柄が木目模様の場合、表面の艶が均一で単調に
なると、天然木に類似した感じにならない。そのため、
表面にエンボス加工等の物理的処理を施して天然木に類
似した感じとしていた。For example, when the design is a wood grain pattern and the surface gloss is uniform and monotonous, it does not look like natural wood. for that reason,
The surface was given a physical treatment such as embossing to make it look similar to natural wood.
しかし、基材か金属板の場合、金属板上に設ける塗膜の
厚さが薄く、全面に渡って均一なエンボスを施すことが
困難であった。However, in the case of the base material or the metal plate, the thickness of the coating film provided on the metal plate is thin, and it is difficult to uniformly emboss the entire surface.
(解決しようとする問題点) 本発明は、基材が金属板である金属化粧板であっても、
表面に均一な凹凸模様を施した金属化粧板を提供するこ
とを目的とする。(Problems to be Solved) Even if the base material is a metal decorative plate, which is a metal plate,
It is an object of the present invention to provide a metal decorative plate whose surface has a uniform uneven pattern.

る。(Means for Solving Problems) The present invention is to form an arbitrary pattern on the surface of a heat-resistant substrate film with a matte varnish containing a thermosetting resin and a matting agent as main components, and heat it to form a pattern. 1 thermosetting resin phase is provided, the thermosetting resin of the same kind as the first thermosetting resin layer is applied to the entire surface, and the second thermosetting resin layer is provided in a semi-cured state. A transparent thermosetting resin different from the second thermosetting resin layer is coated on the entire surface, and a third thermosetting resin layer is provided in a semi-cured state, and a pattern layer made of ink is provided on the surface. As a transfer foil provided, the transfer foil is superposed on a metal plate having an uncured base coating film formed on the surface thereof, and after transfer, the heat-resistant base film is peeled and removed, and heating is performed. It is a method for manufacturing a metal decorative plate having a pattern.

フィルムを剥離すると、第2熱硬化性樹脂の第1熱硬化
性樹脂と接している部分は剥離除去され、その他の部分
は残り、凹凸模様が形成される。(Operation) In the present invention, the first thermosetting resin layer forming the transfer foil is integrated with the heat resistant substrate film. Furthermore, since the second thermosetting resin layer is made of the same thermosetting resin as the first thermosetting resin layer and is in a semi-cured state, the adhesive force between the heat resistant base film and the second thermosetting resin layer is The adhesive force between the second thermosetting resin layer and the third thermosetting resin is smaller, and when the base film is peeled off, the portion of the second thermosetting resin that is in contact with the first thermosetting resin is peeled off. The remaining portion is left, and an uneven pattern is formed.
ここで、第2熱硬化性樹脂層は艶消剤を含んでも含まな
くてもよいが、含む場合は第1熱硬化性樹脂層とは異な
る量とし、好ましくは第1熱硬化性樹脂層より少ない量
を含む状態とすることで、表面の光沢状態を任意に変え
ることができる。Here, the second thermosetting resin layer may or may not contain a matting agent, but in the case of containing the matting agent, the amount thereof is different from that of the first thermosetting resin layer, and it is preferably more than that of the first thermosetting resin layer. By setting the amount to include a small amount, the glossiness of the surface can be changed arbitrarily.

2熱硬化性樹脂層と剥離性を有し、接着力は、耐熱基材
フィルムとの接着力より大きければ目的は達成される。As the transparent thermosetting resin forming the third heat-modified resin layer, specifically, alkyd resin, polyester resin,
A silicone resin can be used, and in the semi-cured state, it has peelability from the second thermosetting resin layer, and if the adhesive force is larger than the adhesive force with the heat-resistant base film, the purpose is achieved.
