Description
本発明は、プラスチックやコート紙からなる基材の表面に、洗いざらしのジーンズ生地模様のような、スウェード調表面を有する模様や図柄などを印刷してなる印刷物とその製造方法、およびそれに用いるスクリーンインキに関する。 The present invention relates to a printed matter obtained by printing a pattern or design having a suede-like surface, such as a washed-out jeans fabric pattern, on the surface of a base material made of plastic or coated paper, a method for producing the same, and a screen ink used therefor About.
スウェード調表面を有する模様等を基材表面に形成する方法として、牛・ブタ等の鞣革表面にジーンズ生地の洗いざらし生地模様を形成する方法が知られている（特許文献１参照）が、プラスチックや紙製の基材に対して、ジーンズ生地のように風合いが良く手触りの柔らかいスウェード調表面を有する模様等を、スクリーン印刷により形成する方法は知られていない。 As a method of forming a pattern having a suede surface on the surface of a base material, a method of forming a washed fabric pattern of jeans fabric on the surface of leather such as cow and pig is known (see Patent Document 1). On the other hand, there is no known method for forming a pattern having a suede-like surface that has a soft texture and a soft touch like a jeans fabric by screen printing.
そこで、本願発明者等は、特許文献２に記載されるような、塩化ビニル系樹脂プラスチゾル組成物に着目し、これを用いて、プラスチックや紙製の基材上にスクリーン印刷により、ジーンズ生地の洗いざらし生地模様を形成し、その上に、特殊塩化ビニル樹脂を含むプラスチゾルインキでオーバーコート層を重ね刷りして印刷物を得た。この印刷物は、ジーンズ生地のように風合いが良く、手触りの柔らかいスウェード調表面を有するものであったが、基材に対する密着性が悪く剥離し易いため、製品として提供することは困難であった。 Therefore, the inventors of the present application pay attention to a vinyl chloride resin plastisol composition as described in Patent Document 2, and using this, screen printing is performed on a plastic or paper base material to make a jeans fabric. A washed fabric pattern was formed, and an overcoat layer was overprinted with a plastisol ink containing a special vinyl chloride resin thereon to obtain a printed matter. Although this printed material has a good texture and a soft suede-like surface like jeans fabric, it has been difficult to provide as a product because of its poor adhesion to the substrate and easy peeling.
本発明はこのような従来事情に鑑みてなされたものであり、その目的とする処は、プラスチックや紙製の基材表面に、洗いざらしのジーンズ生地のように風合いが良く、手触りの柔らかいスウェード調表面を有し、且つ基材に対する密着性に優れた模様、図柄などを、スクリーン印刷により形成することができる印刷物とその製造方法、およびこれに用いるスクリーンインキを提供することにある。 The present invention has been made in view of such a conventional situation, and the object of the present invention is that the surface of a plastic or paper base material has a good texture like a washed-out jeans fabric and has a soft hand feeling. An object of the present invention is to provide a printed matter, a method for producing the same, and a screen ink used therefor, which can form a pattern, a pattern or the like having a surface and excellent adhesion to a substrate by screen printing.
上記目的を達成するために本願発明者等は、塩化ビニル樹脂を含むプラスチゾルインキを用いて基材上にスクリーン印刷した印刷層の上に、発泡剤及び塩化ビニル樹脂を含むプラスチゾルインキを用いてオーバーコート層を重ね刷りした場合、その印刷部分（樹脂組成物）は、表面が、洗いざらしのジーンズ生地のように風合いが良く、手触りの柔らかいスウェード調表面を有するものの、プラスチックや紙製の基材に対する密着性に劣ることを知見した。このような知見に基づき鋭意研究を重ねた結果、プラスチックや紙製の基材表面と前記印刷層の間に、密着性を高めるための層を形成することが、本発明の課題に対し極めて有用であるとの新たな知見を得て、本発明を完成するに至った。 In order to achieve the above object, the present inventors have used a plastisol ink containing a foaming agent and a vinyl chloride resin on a printed layer screen-printed on a substrate using a plastisol ink containing a vinyl chloride resin. When the coat layer is overprinted, the printed part (resin composition) has a soft, suede-like surface that feels soft and feels like a washed-out jeans fabric. It was found that adhesion was inferior. As a result of earnest research based on such knowledge, it is extremely useful for the problem of the present invention to form a layer for improving adhesion between the surface of a base material made of plastic or paper and the printed layer. As a result, the present invention was completed.
すなわち、本発明に係るスウェード調表面を有する印刷物は、アンダーコート用インキを用いて基材上に印刷された下地層と、塩化ビニル樹脂を含むプラスチゾルインキを用いて前記下地層上に重ね刷りしてなる中間層と、発泡剤及び塩化ビニル樹脂を含むプラスチゾルインキを用いて前記中間層上に重ね刷りしてなるオーバーコート層と、からなることを特徴とする。 That is, a printed matter having a suede-like surface according to the present invention is overprinted on an undercoat layer printed on a substrate using an undercoat ink and on the undercoat layer using a plastisol ink containing a vinyl chloride resin. And an overcoat layer formed by overprinting the intermediate layer using a plastisol ink containing a foaming agent and a vinyl chloride resin.
このように、基材と中間層の間に、アンダーコート用インキにより印刷された下地層を形成することで、プラスチックや紙製の基材に対する中間層の密着性が大幅に向上する。また、プラスチゾルインキに含まれる発泡剤の作用により、オーバーコート層の表面が、微細な凹凸を有する梨地模様のような表面となって、洗いざらしのジーンズ生地のように風合いが良く、手触りの柔らかいスウェード調表面を有するようになる。 Thus, by forming the base layer printed with the undercoat ink between the base material and the intermediate layer, the adhesion of the intermediate layer to the plastic or paper base material is greatly improved. In addition, due to the action of the foaming agent contained in the plastisol ink, the surface of the overcoat layer becomes a textured surface with fine irregularities, and the texture is as good as a washed-out jeans fabric, and the suede is soft to the touch. It has a toned surface.

アンダーコート用インキによる下地層の形成をせず、基材上に直接中間層を印刷し、その上にオーバーコート層を重ね刷りしたこと以外は実施例１と同様にして印刷物を得た。
(Comparative Example 4)
A printed matter was obtained in the same manner as in Example 1 except that the undercoat layer was not formed with the undercoat ink, the intermediate layer was printed directly on the substrate, and the overcoat layer was overprinted thereon.
比較例１〜３で得られた印刷物の表面は、洗いざらしのジーンズ生地模様のような風合いが良く手触りの柔らかいスウェード調表面を有するものであった。しかし、これら印刷物に対し、前述の密着性試験を数回行った処、０〜３点という低評価の結果であった。また爪で引っ掻いた場合の剥離度合いを実施例１、２と比較した結果、明らかに剥離しやすく、印刷物としては不完全なものであった。
また、比較例４で得られた印刷物は、中間層、オーバーコート層が基材に対して明らかに密着せず、比較例１〜３以上に、印刷物としては不完全なものであった。
The surface of the printed matter obtained in Comparative Examples 1 to 3 had a soft suede-like surface with a good texture such as a washed jeans fabric pattern. However, the results of low evaluation of 0 to 3 points were obtained when the above-mentioned adhesion test was performed several times on these printed materials. Moreover, as a result of comparing the degree of peeling when scratched with a nail with Examples 1 and 2, it was clearly easy to peel off, and the printed matter was incomplete.
Further, in the printed matter obtained in Comparative Example 4, the intermediate layer and the overcoat layer were not clearly adhered to the substrate, and the printed matter was incomplete in Comparative Examples 1 to 3 or more.
以上の結果から、本発明に係るアンダーコート用インキを用いた場合、プラスチック又は紙製の基材に対する中間層、オーバーコート層の密着性が向上することが確認できた。 From the above results, it was confirmed that when the undercoat ink according to the present invention was used, the adhesion of the intermediate layer and the overcoat layer to a plastic or paper substrate was improved.
