Description
【０００１】
【産業上の利用分野】
本発明は、ラッピング加工やラミネート加工など、複雑な形状に追従して加工を可能とする、柔軟性を有するエンボス化粧シートに関するものである。
【０００２】
【従来の技術】
従来より、幅木、額縁、框などの複雑な形状に追従するラッピング加工用化粧シート、合板などにラミネート加工して化粧板にする柔軟性を有する化粧シートは、一般的に広い範囲で使用されている。
【０００３】
例えば図３に示すように、原紙（３１）上に、柄印刷層（３２）とマット（光沢が鈍い）樹脂層（３４）を塗布、乾燥させた層上に、グロスインキ層（３５）とマットインキ層（３６）で意匠性を表現すると共に、原紙及び各層厚を薄くして柔軟性を持たせた、ラッピング加工などに用いられる化粧シート（３０）が知られている。
【０００４】
しかしながら、この化粧シート（３０）においては、ラッピング加工などに適した柔軟性を有する化粧シートにするために、肉厚感のある樹脂層にする樹脂塗料を塗布することができなかった。すなわち、樹脂塗料を塗布、乾燥すると硬化して化粧シート全体が硬くなるために、ラッピング加工などにおいて被着体の複雑な形状に追従することが難しくなる。従って、ラッピング加工後に改めて樹脂塗料の塗装を行っているために、コスト的に高価なものになっていた。また、ラッピング加工のように、複雑な形状に追従するような柔軟性のある樹脂を含浸させたりして樹脂層を薄くすると、（Ａ）耐摩耗性が低下する、（Ｂ）浅いエンボス加工しかできずラッピングの際に化粧シートが破け、意匠性も劣る、などの問題が起きている。
【０００５】
【発明が解決しようとする課題】
すなわち、化粧シート単体では意匠性、塗装感、耐摩耗性、耐溶剤性などの表面物性、形状に合わせた柔軟性、エンボス適性、加工適性などを同時に満たす化粧シートを得ることは難しかった。このため肉厚感があり、しかも、複雑な形状に追従するラッピング加工などに用いるエンボス化粧シートの要請がなされていた。そこで本発明は、原紙上に樹脂印刷層を設けて、原紙に樹脂を含浸させるとともに、原紙上に樹脂層を形成して、エンボス加工などを可能とした化粧シートを提供するものである。
【０００６】
【課題を解決するための手段】
上記の課題を解決するために本発明は、原紙（１１）上に柄印刷層（１２）を設けてから、分子量が２００００〜３００００のポリエステル系樹脂を塗布し、原紙（１１）上にディップ含浸するとともに、原紙（１１）上に３０〜４０ｇ／ｍ２ の透明又は半透明の含浸樹脂層（１５）を設けて、この含浸樹脂層（１５）上に導管模様（Ｅ）をエンボスして、この導管凹部に導管インキ（１３）を設けたことを特徴とするものである。
【０００８】
【作用】
上記に述べたように、本発明のエンボス化粧シートによれば、表面に含浸樹脂層（１５）が塗布、含浸されているため塗装感が発現して意匠性が向上すると共に、表面に樹脂層を厚く形成できるので深いエンボス加工が可能となり、耐摩耗性が生じる。また、この含浸樹脂層（１５）として、分子量が２００００〜３００００のポリエステル系樹脂を用いることで、樹脂層が厚くともシートに柔軟性が生じて複雑な形状に対しても追従性の良い化粧シートとなる。
【０００９】
【実施例】
以下実施例により本発明を詳細に説明する。
図１は、本発明の実施例におけるラッピングなどに用いるエンボス化粧シートの説明図である。また、図２は、導管模様のエンボス加工用の賦型シートの説明図（ａ）と、樹脂含浸シートの説明図（ｂ）である。
【００１０】
図２（ａ）に示すように、原紙（１１）としては坪量８０ｇ／ｍ２ のチタン紙（紀州製紙（株）社製）を用いて、この上に、複数色の硝化綿インキ（東洋インキ製造（株）社製）により木目柄などをグラビア印刷方式で印刷して、柄印刷層（１２）を設ける。さらに、この全面に、含浸樹脂層（１５）を設けて樹脂含浸シート（１０ａ）とする。この含浸樹脂層（１５）としては、分子量が２００００〜３００００のポリエステル系樹脂を塗布する。この樹脂は原紙（１１）にディップ含浸するとともに、原紙（１１）上に３０ｇ〜４０ｇ／ｍ２ の含浸樹脂層（１５）が形成されるので、耐摩耗性、耐溶剤性が生じる。
【００１１】
本実施例においては、前記の樹脂含浸シート（１０ａ）の表面に意匠性を付与するために、片面に微細な凹凸模様を形成した離型性のある賦型シート（２０）を用いて導管模様（Ｅ）のエンボス加工を行った。この賦型シート（２０）は、図２（ａ）に示すように、坪量３０ｇ／ｍ２ の薄紙の支持紙（２１）上に、ポリプロピレン樹脂層（２２）を設けて、この樹脂層上に導管模様の微細な凹凸模様を形成したものである。この賦型シート（２０）の凹凸模様面と、樹脂含浸シート（１０ａ）の含浸樹脂層（１５）面を重ね合わせて、１４０℃で１分間、圧力２〜５ｋｇ／ｃｍ２ により含浸樹脂層（１５）面上に導管模様（Ｅ）を形成した後、さらに、この形成した導管模様（Ｅ）の凹部に、ワイピング方式により導管インキ（１３）を設けることで、図１に示すような、エンボス化粧シート（１０）が得られる。
【００１２】
【発明の効果】
本発明は以上の構成であるから、下記に示す如き効果がある。
すなわち、表面に透明又は半透明の樹脂が塗布、含浸されているため塗装感が発現し意匠性に優れたものとなる。この表面には含浸されずに残る樹脂層が厚いため耐摩耗性に優れた化粧シートが得られる。また、表面の樹脂層が厚く残るのでシート表面に深い導管模様などをエンボス加工することができ、木目ではより本物の木材に近い意匠感が得られる。
さらに、得られるエンボス化粧シートは、樹脂層が厚くてもシートに柔軟性があるために、幅木、額縁、框などの複雑な形状の被着体にラッピング加工が可能となり、しかも、複雑な形状に対して追従性のよいシートとなる。

[Industrial applications]
TECHNICAL FIELD The present invention relates to a flexible embossed decorative sheet that enables processing following a complicated shape such as lapping or laminating.
[0002]
[Prior art]
Conventionally, decorative sheets for wrapping that follow complex shapes such as skirting boards, picture frames, frames, etc., and decorative sheets that have the flexibility to be laminated into plywood and made into decorative boards are generally used in a wide range. ing.
[0003]
For example, as shown in FIG. 3, on a base paper (31), a pattern printing layer (32) and a mat (dull gloss) resin layer (34) are applied and dried, and a gloss ink layer (35) is formed. There is known a decorative sheet (30) used for lapping or the like, in which a matte ink layer (36) expresses design properties, and is made flexible by making the thickness of a base paper and each layer thin.
[0004]
However, in this decorative sheet (30), in order to obtain a decorative sheet having flexibility suitable for lapping or the like, a resin paint for forming a thick resin layer could not be applied. In other words, when the resin paint is applied and dried, it hardens and the whole decorative sheet becomes hard, so that it becomes difficult to follow the complicated shape of the adherend in lapping or the like. Therefore, since the resin coating is newly applied after the lapping, the cost is high. Further, when the resin layer is thinned by impregnating with a flexible resin that follows a complicated shape as in the case of lapping, (A) abrasion resistance is reduced, and (B) only shallow embossing is performed. There are problems such as the decorative sheet being broken during wrapping and poor design.
[0005]
[Problems to be solved by the invention]
That is, it has been difficult to obtain a decorative sheet that simultaneously satisfies the surface properties such as design, painting, abrasion resistance, solvent resistance, etc., flexibility according to the shape, embossing suitability, processing suitability, etc. by using the decorative sheet alone. For this reason, there has been a demand for an embossed decorative sheet which has a sense of thickness and is used for lapping or the like which follows a complicated shape. Therefore, the present invention provides a decorative sheet in which a resin printing layer is provided on a base paper to impregnate the resin into the base paper, and a resin layer is formed on the base paper to enable embossing or the like.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a pattern printing layer (12) on a base paper (11), then applies a polyester resin having a molecular weight of 20,000 to 30,000, and dips and impregnates the base paper (11). And 30-40 g / m 2 on the base paper (11). Wherein a transparent or translucent impregnated resin layer (15) is provided, a conduit pattern (E) is embossed on the impregnated resin layer (15), and a conduit ink (13) is provided in the concave portion of the conduit. It is assumed that.
[0008]
[Action]
As described above, according to the embossed decorative sheet of the present invention, since the impregnated resin layer (15) is applied and impregnated on the surface, a feeling of painting is exhibited and the design is improved, and the resin layer is formed on the surface. Can be formed thick, so that deep embossing can be performed, resulting in abrasion resistance. Further, by using a polyester-based resin having a molecular weight of 20,000 to 30,000 as the impregnated resin layer (15), the sheet is flexible even if the resin layer is thick, and the decorative sheet has good follow-up ability to a complicated shape. It becomes.
[0009]
【Example】
Hereinafter, the present invention will be described in detail with reference to examples.
FIG. 1 is an explanatory diagram of an embossed decorative sheet used for wrapping and the like in an example of the present invention. FIG. 2 is an explanatory diagram (a) of an embossing sheet for embossing a conduit pattern and an explanatory diagram (b) of a resin-impregnated sheet.
[0010]
As shown in FIG. 2A, as the base paper (11), a titanium paper having a basis weight of 80 g / m 2 (manufactured by Kishu Paper Co., Ltd.) was used, and a plurality of nitrified cotton inks (Toyo A wood pattern or the like is printed by a gravure printing method by Ink Manufacturing Co., Ltd.) to provide a pattern printing layer (12). Further, an impregnated resin layer (15) is provided on the entire surface to obtain a resin-impregnated sheet (10a). As the impregnated resin layer (15), a polyester resin having a molecular weight of 20,000 to 30,000 is applied. This resin dips and impregnates the base paper (11), and the impregnated resin layer (15) of 30 g to 40 g / m 2 is formed on the base paper (11), so that abrasion resistance and solvent resistance are generated.
[0011]
In this embodiment, in order to impart a design property to the surface of the resin-impregnated sheet (10a), a release pattern forming sheet (20) having a fine uneven pattern formed on one side is used. The embossing of (E) was performed. As shown in FIG. 2A, the imprint sheet (20) is provided with a polypropylene resin layer (22) on a thin paper support paper (21) having a basis weight of 30 g / m 2 , and A fine concave and convex pattern of a conduit pattern is formed thereon. The uneven pattern surface of the shaping sheet (20) and the surface of the impregnated resin layer (15) of the resin-impregnated sheet (10a) are overlapped, and the pressure is 2 to 5 kg / cm 2 at 140 ° C. for 1 minute. 15) After the conduit pattern (E) is formed on the surface, the conduit ink (13) is further provided in the concave portion of the formed conduit pattern (E) by a wiping method, thereby embossing as shown in FIG. A decorative sheet (10) is obtained.
[0012]
【The invention's effect】
The present invention having the above configuration has the following effects.
That is, since a transparent or translucent resin is applied and impregnated on the surface, a feeling of painting is exhibited and the design is excellent. Since the resin layer remaining without being impregnated on this surface is thick, a decorative sheet having excellent wear resistance can be obtained. Further, since the resin layer on the surface remains thick, a deep conduit pattern or the like can be embossed on the sheet surface, and the grain of wood gives a design feeling closer to that of real wood.
Furthermore, since the obtained embossed decorative sheet has flexibility even when the resin layer is thick, it is possible to wrap an adherend having a complicated shape such as a skirting board, a frame, a frame, and the like. It becomes a sheet with good followability to the shape.
