Description

【発明の詳細な説明】 (発明の利用分野) 本発明は、有価証券類の識別手段として触覚を利用することにより、真偽及び種類の判定を可能にし、かつ視覚の併用によって判定を更に確実にするセキュリティスレッド入り証券用紙に関するものものである。 DETAILED DESCRIPTION OF THE INVENTION The present invention (Field of Invention), by utilizing the tactile as identification means securities, enabling authenticity and type of determination, and further secure the determination by visual combination it is those related to security thread containing securities paper to be in.

(発明の背景) 有価証券類、例えば広範囲の流通手段として利用されている銀行券は最高度の公的信用が必須条件で、その信用維持のために偽造及び変造防止対策が施されている。 Securities, (Background of the Invention), for example bank notes, which is used as a wide range of distribution means in the public credit is essential conditions of the highest degree, forgery and tampering prevention measures are applied for the credit maintenance. 現行銀行券には、触覚に基づく「手触り」によって真偽及び券種を判定するための識別マーク付与されていることは周知であり有効な偽造防止策であるが、別の方法として銀行券、有価証券等の偽造防止策として慣用されているセキュリティスレッドに触覚による識別機能を付与し、これを紙層内に埋設することによって新たな識別及び偽造防止効果を期待することができる。 The current banknotes, although it has been granted identification mark for determining the authenticity and denomination by haptic "hand" are effective anti-counterfeit measures are well known, banknotes alternatively, an identification function tactile given to security thread which is a commonly used anti-counterfeit measures such securities, which can be expected a new identification and anti-counterfeiting effect by embedding the paper layer.

(発明の目的) 本発明は、以上のような観点から、触覚によって確実に識別できる、セキュリティスレッドを完全に埋設した証券用紙を得ることを目的としている。 INVENTION An object of the present invention, from the above viewpoint, can be reliably identified by tactile, aims at obtaining a security sheet having completely embedded security thread.

(発明の概要) 本発明は、熱可塑性合成樹脂フィルムの片面又は両面に、熱可塑性合成樹脂を用いて部分的に凸型隆起部を設け、ついでこれを糸条形態に細断した片面又は両面に部分的に凸型隆起部を有するセキュリティスレッドを抄紙段階で紙層表面に露出しないように紙層内のほぼ定位置に挿入し、該セキュリティスレッドの凸型隆起部の紙厚が他の部分の紙厚よりも明らかに厚く、紙面に軽く触るだけで隆起状態を識別できる証券用紙である。 SUMMARY OF THE INVENTION The present invention, on one or both sides of a thermoplastic synthetic resin film, using a thermoplastic synthetic resin partly provided with a raised ridge, then one or both sides chopped it to yarn form partially substantially inserted into position, the paper thickness other parts of the raised ridge of the security thread of raised ridge paper layer so as not to be exposed on the paper layer surface security thread papermaking step with the clearly thicker than the sheet thickness of a security papers which can be identified only by the raised state touching lightly on paper. 更に、前記凸型隆起部に着色剤又は発光剤を付与し、紙の表面又は裏面に露出した場合の着色又は発光状態とは異なる一種の「ぼけ」、すなわち紙を透過光又は反射光で観察する場合に、前記凸型隆起部の周辺に淡色効果を発現するセキュリティスレッドを、用紙の表面又は裏面に露出することなく紙層内に完全に埋設した証券用紙である。 Furthermore, colorant or impart emitting agent to the raised ridge, "blurring" of the different kind is a colored or luminescent state when exposed to the surface or back surface of the paper, i.e. observe the paper by transmitted light or reflected light when the security thread expressing hypochromic effect around the raised ridge, a security sheet that has completely embedded in the paper layer without being exposed on the surface or back surface of the paper.

(発明の詳述) 本発明の凸型隆起部を有するセキュリティスレッドを埋設した証券用紙は「手触り」による触覚から、例えば銀行券の真偽を前記凸型隆起部の有無で迅速に判定でき、 Security papers which are embedded security thread having a raised ridge of (recitations INVENTION) The present invention is a tactile by "hand", quickly be determined e.g. the authenticity of banknotes in the presence or absence of the raised ridge portions,
また前記凸型隆起部の個数や位置で銀行券の券種も判定できる。 The denomination of the banknotes by the number and positions of the raised ridge portions may be determined. 更に、該セキュリティスレッドの凸型部分に着色剤を付与することにより透過光又は反射光で「ぼけ」 Furthermore, "blurring" in transmitted or reflected light by applying a colorant to a convex portion of the security thread
に著しく類似した淡色効果が付加され、発光剤の付与によっても紫外線下で前記の淡色効果を発現する。 Remarkably similar to hypochromic effect was is added, also express hypochromic effect of the under UV by application of the light emitting agent.

本発明は、このような凸型隆起部を有するセキュリティスレッド入り証券用紙を提供する。 The present invention provides a security thread containing security papers having such a raised ridge.

本発明で使用されるセキュリティスレッドの材料には、 The security thread of the materials used in the present invention,
熱可塑性合成樹脂として慣用されるポリビニルアルコール、酢酸ビニル樹脂、塩化ビニル樹脂、スチロール樹脂等があるが、好ましくはポリビニルアルコールで、この場合のケン化度は99.8%以上である。 Polyvinyl alcohols which are conventionally used as the thermoplastic synthetic resin, a vinyl acetate resin, vinyl chloride resin, there are styrene resins, preferably polyvinyl alcohol, saponification degree in this case is 99.8% or more. また、凸型隆起部は前記材料の片面又は両面に、前記熱可塑性合成樹脂で部分的に凸型、例えば接着性のビニル系樹脂でドット又はバー状に付与する。 Also, the raised ridge applied to one or both surfaces of the material, partly convex in the thermoplastic synthetic resin, in a dot or a bar shape, for example, adhesion of the vinyl resin. また、凸型隆起部に付与する着色剤に染料又は顔料、例えば布地用の塩基性染料又は印刷インキ用顔料、発光剤には表示用の昼光蛍光顔料又はランプ用蛍光体等が使用できる。 Further, a dye or pigment colorant to impart to the raised ridge, for example, basic dye or printing ink pigments for the fabric, daylight fluorescent pigment or a lamp phosphor, etc. for display on the luminescent agent can be used.

本発明におけるセキュリティスレッドの凸型隆起部は、 The raised ridge of the security thread of the present invention,
ドット又はバー状のパターンを切り抜いた型版をベースフィルムの片面に置き、高粘度タイプの市販のビニル系接着剤を前記隆起部に相当する切り抜き部分に注入り、 Cut type version of a dot or a bar-like patterns placed on one surface of the base film, Ri injecting commercially available vinyl-based adhesive having a high viscosity type cutout portion corresponding to the ridge,
余分の接着剤をスクィージして取り除き、固化させることによって、第1図の部分的に凸型に隆起したベースフィルムを得る。 Removed by squeegee the excess adhesive, by solidifying, to obtain a raised base film partially convex of FIG. 1. また、ベースフィルムの両面に部分的に凸型隆起部を付与する場合には、上記のドット又はバー状に切り抜いた型版とビニル系接着剤により、片面ごとに固化させることによって、第2図の両面で部分的に凸型に隆起したベースフィルムを得る。 Further, in the case of imparting partially raised ridge on both sides of the base film, the mold plate and a vinyl adhesive cut into said dot or bar shape, by solidifying per one side, Figure 2 obtaining a raised base film partially convex in both. これらのベースフィルムを、例えば幅1mmに細断し、凸型隆起部を有するセキュリティスレッドを得る。 These base films, chopped example, width 1 mm, to obtain a security thread having a raised ridge. また、本発明のセキュリティスレッドを量産規模において作製する方法の例としては、スクリーン印刷法を適用し、スクリーン目に相当する部分で前記の凸型隆起部を付与したベースフィルムを作製し、これを細断して凸型隆起部を有するセキュリティスレッドを製造する。 Further, as an example of a method of manufacturing a security thread of the present invention in a mass-production scale, by applying a screen printing method, to prepare a base film provided with said raised ridge at a portion corresponding to the screen first, this chopped to producing security thread having a raised ridge.

このようにして得られた凸型隆起部を有するセキュリティスレッドを抄紙段階で、用紙の巻取方法に沿いほぼ定位置に挿入して、第3図(A)、(B)に示すような紙層内に完全に埋設した証券用紙を製造する。 Thus to obtained in papermaking step a security thread having a raised ridge, the insert substantially fixed position along the winding process of paper, FIG. 3 (A), as shown in (B) Paper producing security papers which were completely embedded in the layer.

(発明の効果) 本発明の証券用紙は、凸型隆起部を有するセキュリティスレッドによって、触覚による真偽及び種類の判定ができ、更に着色剤又は発光剤によっても触覚の他に視覚によっても判定が可能であるので、極めて有用な識別及び偽造防止効果がある。 Security papers of the present invention (the effect of the invention), the security thread having a raised ridge, can authenticity and type of determination by touch, determination by visual other haptic by further colorants or luminescent agent since possible, there is a very useful identification and anti-counterfeiting effect. また、モノロ及びカラー複写物においても凸型隆起部を有するセキュリティスレッドの再現は困難であり、複写防止効果がある。 Further, Monoro and reproducibility of security thread having a raised ridge even color copying thereof is difficult, there is a copy preventing effect.

(実施例) 以下、本発明の実施例を示すが、本発明はこれに限定されるものではない。 (Example) Hereinafter, Examples of the present invention, the present invention is not limited thereto. なお、以下に示す部又は%は重量基準である。 All parts or percentages given below are by weight.
