Description

本発明は金属箔の表面に直接印刷することが出来る印刷用金属箔シートに関するものである。   The present invention relates to a printing metal foil sheet that can be directly printed on the surface of a metal foil.

従来は金属箔に模様等の印刷を施す場合、金属箔の表面に樹脂膜層を形成しその上に各種印刷を施しているのである。
しかし、樹脂膜層の存在によって箔特有の美しさや輝きが損なわれることは否めない。 Conventionally, when printing a pattern or the like on a metal foil, a resin film layer is formed on the surface of the metal foil, and various printings are performed thereon.
However, it cannot be denied that the beauty and brightness unique to the foil are impaired by the presence of the resin film layer.

これは、金属箔に直接印刷を施すと、印刷機のローラーに残るインクの粘着力によって、金属箔が部分的に剥ぎ取られ該部分の補修が必要となること、更にローラーに接着した金属箔の除去も必要となり、手数が掛かると同時に品質の劣る製品となるのである。   This is because when printing is performed directly on the metal foil, the metal foil is partially peeled off due to the adhesive force of the ink remaining on the roller of the printing machine, and the portion needs to be repaired. Further, the metal foil adhered to the roller It is also necessary to remove this, which is troublesome and at the same time becomes a product with inferior quality.

例えば、特開平０５−３０５６９３では薄用紙の基材層に接着剤層と金属箔層とが順次積層され、金属箔層表面に凹凸エンボス加工を施し、該エンボスの凹部を埋設するように透明な合成樹脂層を被設し、この合成樹脂層上に適宜印刷ができるようにしたものがある。
特開平０５−３０５６９３ For example, in Japanese Patent Application Laid-Open No. 05-305693, an adhesive layer and a metal foil layer are sequentially laminated on a thin paper base layer, and the surface of the metal foil layer is embossed so as to be transparent so as to embed a concave portion of the emboss. There is one in which a synthetic resin layer is provided so that printing can be appropriately performed on the synthetic resin layer.
JP 05-305893

そこで、本発明は金属箔の表面に印刷用の加工を施すことなく直接印刷することが可能で、インクとの結合も強固となる印刷用金属箔シートを提供せんとするものである。   Accordingly, the present invention is intended to provide a printing metal foil sheet that can be directly printed on the surface of the metal foil without being subjected to printing processing, and has a strong bond with ink.

本発明の印刷用金属箔シートは、基材シート上に、ホットメルト型接着剤層を介して、ピンホールが散設された金属箔を被設し、熱圧着により、金属箔のピンホール内に充満したホットメルト型接着剤が金属箔表面まで達して金属箔面に滲み出て基材シートと接着させたことを特徴とするものである。   In the metal foil sheet for printing of the present invention, a metal foil in which pinholes are scattered is placed on a base material sheet via a hot-melt adhesive layer, and the metal foil pinhole is formed by thermocompression bonding. The hot-melt adhesive filled in the metal foil reaches the surface of the metal foil, oozes out on the surface of the metal foil, and is bonded to the base sheet.

基材シートと金属箔の熱圧着時に、溶融したホットメルト型接着剤が金属箔のピンホール内、及び金属箔の表面にまで達して金属箔面に滲み出て基材シートと金属箔とが強固に接着することになる。   At the time of thermocompression bonding between the base sheet and the metal foil, the molten hot melt adhesive reaches the inside of the metal foil pinhole and the surface of the metal foil and oozes out on the surface of the metal foil to form the base sheet and the metal foil. It will adhere firmly.

本発明は、基材シートと金属箔との接着が互いの当接する面同士に止まらず、金属箔に形成したピンホールから金属箔の表面にも達した接着剤によって、金属箔との当接する面、金属箔の内部及び金属箔の表面に連続した接着剤が浸透して接着するものであるから、強固な接着となる効果を有するものである。   In the present invention, the adhesion between the base sheet and the metal foil does not stop at the surfaces where they abut against each other, but the adhesive that reaches the surface of the metal foil from the pinhole formed in the metal foil makes contact with the metal foil. Since the continuous adhesive penetrates and adheres to the surface, the inside of the metal foil, and the surface of the metal foil, it has an effect of strong adhesion.

そして、接着剤にホットメルト型接着剤を用いたため、加熱により溶融した接着剤が当接面へ均質に敷延すると共に、圧着により金属箔のピンホールへ充満し、更に金属箔の表面にまで達するものとなる効果を得られるのである。   And since the hot melt type adhesive was used for the adhesive, the adhesive melted by heating was uniformly spread on the contact surface, filled into the pinhole of the metal foil by crimping, and further to the surface of the metal foil The effect that will be achieved is achieved.

更に、湿気によるカビの発生を防止し基材シートの劣化を防ぎ腐食せず、金属箔の表面にはピンホールから噴出した接着剤が残存するため、金属箔の表面を押えて接着力を補強すると同時に、印刷したインクとの結合も良好となる効果も得られるのである。   In addition, it prevents mold from being generated by moisture, prevents deterioration of the base sheet, does not corrode, and the adhesive sprayed from the pinholes remains on the surface of the metal foil, thereby reinforcing the adhesive force by pressing the surface of the metal foil. At the same time, the effect of improving the bond with the printed ink can be obtained.

したがって、直接金属箔面に印刷を施しても、印刷機のローラーに残るインクの粘着力によって、金属箔が部分的に剥ぎ取られる虞はなく、美麗な印刷を確保できると共に、箔特有の美しさや輝きが損なわれることはないのである。   Therefore, even if printing is performed directly on the surface of the metal foil, there is no risk that the metal foil will be partially peeled off due to the adhesive force of the ink remaining on the rollers of the printing press, and it is possible to ensure beautiful printing and to obtain the beauty unique to the foil. There is no loss of strength and shine.

本発明の実施の形態を図面に基づいて説明する。
図１は本発明の一実施の形態を示す断面図であり、本発明の印刷用金属箔シートは、基材シート１上にホットメルト型接着剤層２を介して金属箔３が積層され、基材シート１と金属箔３は介在したホットメルト型接着剤層２により接着している。 Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing an embodiment of the present invention. In the metal foil sheet for printing of the present invention, a metal foil 3 is laminated on a base sheet 1 via a hot-melt adhesive layer 2, The base sheet 1 and the metal foil 3 are bonded by an intervening hot melt adhesive layer 2.

金属箔３にはピンホール４が散在して形成してあり、接着時の加熱圧着でホットメルト型接着剤層２の溶融した接着剤２がこのピンホール４内にも充満し、金属箔３の表面にまで達して半球状５を形成して固化している。   Pinholes 4 are formed in the metal foil 3 in a scattered manner, and the melted adhesive 2 of the hot-melt adhesive layer 2 is filled in the pinhole 4 by thermocompression bonding at the time of bonding. The hemisphere 5 is formed and solidified.

基材シート１は、適当な紙材、樹脂シートや布地等を用いて良く、ホットメルト型接着剤層２との関係で、樹脂に対して浸透性が少ないものや、接着性を良くするためポリアクリルマイドなどの合成樹脂を混入したものを用いるのが最適である。   For the base material sheet 1, an appropriate paper material, a resin sheet, a fabric, or the like may be used. It is optimal to use a material mixed with a synthetic resin such as polyacrylamide.

ホットメルト型接着剤層２は加熱溶融性の高いホットメルト型の合成樹脂を選択し、例えば、EVA系ホットメルト型合成樹脂を挙げることができる。   For the hot-melt adhesive layer 2, a hot-melt type synthetic resin having a high heat-melting property is selected, and examples thereof include an EVA-based hot-melt type synthetic resin.

金箔、銀箔やアルミ箔等の金属箔３に散設するピンホール４は、レーザー光線を利用すれば簡単に形成でき、また、金属製のブラシやサンドペーパーを金属箔３へ押しつけることでも形成することが出来る。   The pinholes 4 scattered on the metal foil 3 such as gold foil, silver foil or aluminum foil can be easily formed by using a laser beam, and can also be formed by pressing a metal brush or sandpaper against the metal foil 3. I can do it.

図２は基材シート１上に、ホットメルト型接着剤層２を介して、ピンホール４が散設された金属箔３を被設し、熱圧着により、金属箔３のピンホール４内に充満したホットメルト型接着剤２が金属箔表面まで達して基材シート１と接着させた前記印刷用金属箔シートに、更に金属箔３の表面に印刷をしてインク層６形成して装飾を施した断面図である。   In FIG. 2, a metal foil 3 in which pinholes 4 are scattered is placed on a base sheet 1 with a hot melt adhesive layer 2 interposed therebetween, and the metal foil 3 is inserted into the pinholes 4 by thermocompression bonding. The filled hot-melt adhesive 2 reaches the surface of the metal foil and is bonded to the base sheet 1, and the surface of the metal foil 3 is further printed to form an ink layer 6 for decoration. It is the applied sectional view.

金属箔３と合成樹脂であるホットメルト型接着剤２は、湿気によるカビの発生を防止し基材シート１の劣化を防ぎ腐食しない。
また、ピンホール４から金属箔３の表面に突出したホットメルト型接着剤２がインク層６と強力に結合してインクの剥離や剥落を阻止するものとなり、印刷物の半永久的な保存が可能となる。 The metal foil 3 and the hot-melt adhesive 2 that is a synthetic resin prevent the generation of mold due to moisture, prevents the base sheet 1 from deteriorating, and does not corrode.
In addition, the hot melt adhesive 2 protruding from the pinhole 4 to the surface of the metal foil 3 is strongly bonded to the ink layer 6 to prevent the ink from peeling or peeling, and the printed matter can be stored semi-permanently. Become.
