【０００１】
【産業上の利用分野】
本発明は、各種くじ類、学習具、玩具等に好適に用いられる印刷物に係るものであり、詳しくは隠れた文字や絵柄の画像が摩擦、引っ掻き等により現れるようにした特殊印刷物に関するものである。
【０００２】
【従来の技術】
従来、この種の印刷物として、印刷基材上に硬貨の金属よりも硬度の大きい材料を含むインキ組成物で文字や絵柄の画像を印刷したもの、すなわちその印刷部分を硬貨で擦ると硬貨の金属が削り取られ、削り取られた金属によって印刷部分が着色され、より明瞭に視認し得る状態となることを利用したものが知られている（特開昭６２−２９７１９６号公報参照）。
【０００３】
【発明が解決しようとする課題】
従来の技術で述べた印刷物は、一般のスクラッチクジのように銀インキを用いてシルクスクリーン印刷により隠蔽層を形成する工程を必要とせず、低コストで効率良く製造できるという優れた利点を有してはいるものではあるが、印刷物に形成された画像が硬貨で擦らなくても認識できてしまうという欠点がある。したがって、例えばくじの当たり外れや問題集の回答欄などに利用する場合にあっては、印刷基材上の一領域に硬貨の金属よりも硬度の大きい材料を含むインキ組成物で第１の画像を印刷形成するとともに、該印刷基材と同一印刷基材か又は別体の印刷基材上に硬貨の金属よりも硬度の小さな比較的軟らかい材料を含むインキ組成物で第１の画像と外観が同様な第２の画像を印刷形成しておき、摩擦したり引っ掻いたりしてすることにより一方の画像のみを変色させるようにするといったように、その利用形態が限られるという問題点があった。
【０００４】
本発明は、上記のような問題点に鑑みなされたものであり、その目的とするところは、低コストでありながらも、擦る前の状態では画像が視認できないようにした特殊印刷物を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明の特殊印刷物は、基材上に均一な網点で構成される平網を設けた印刷物であって、文字や絵柄の画像を構成する領域の網点を硬貨の金属よりも硬度の大きい材料を含むインキ組成物で印刷するとともに、それ以外の領域の網点を硬貨の金属と同等か若しくはそれよりも小さい硬度を有する材料を含むインキ組成物で印刷し、硬貨で擦ることにより画像部分の網点が着色化して画像が視認できるようにするとともに、印刷できる範囲で小さくかつ現れた画像が判別できる範囲で間隔をあけて網点を形成したことを特徴とするものである。
【０００６】
なお、特開昭６２−２９７１９６号公報にも記載されているように、硬貨の金属よりも硬度の大きい材料としては酸化チタン、酸化アルミニウム、二酸化けい素、酸化クロムなどを利用することができる。また、硬貨の金属と同等か若しくはこれ以下の硬度の比較的軟らかい材料としては硫酸バリウム、炭酸カルシウム、水酸化アルミニウム、カオリナイト、タルク、炭酸マグネシウム、有機顔料、染料などを適宜用いることができる。
【０００７】
【作用】
上述の構成からなる本発明の特殊印刷物では、画像を構成する領域の網点とそれ以外の領域の網点とが連続し、見た目には全面平網の状態を呈して画像が隠れた状態となる。そして、硬貨で擦ることにより、画像部分の網点のみが黒色に変化して浮き出た状態で見えるようになる。
【０００８】
【実施例】
以下、本発明の実施例について図面を参照して説明する。
【０００９】
図１に本発明の一実施例としての特殊印刷物の一部分を示す。この印刷物１は基材２としての板紙、例えば「 Jet star 」、「 Jet A マニラ」（大昭和製紙製、坪量３１０ｇ／ｍ2 ）、「シルクＧ」（興陽製紙製、坪量３１０ｇ／ｍ2 ）等の上に均一な網点３で構成される平網を設けたものであり、図２に示すように、網点３のうち画像を構成する領域４（一点鎖線で囲まれた領域）の網点３ａは表１に示す配合Ａのインキ組成物を用いてオフセット印刷（又は活版印刷）により印刷されており、一方、それ以外の領域５の網点３ｂは表１に示す配合Ｂのインキ組成物を用いて同様にオフセット印刷（又は活版印刷）により印刷されている。
【００１０】
【表１】
ここで、配合Ａのインキ組成物に含まれる酸化チタンのモース硬度は５．５〜７．０（ルチル型＝６．０〜７．０、アナターゼ型＝５．５〜６．０）であり、硬貨の材料として一般に用いられている金属のモース硬度（ニッケル＝３．８、黄銅＝３．０〜４．０、銅＝３．０）よりもはるかに大きい。また、配合Ｂのインキ組成物に含まれるＣａＣＯ3 のモース硬度は３．０であり、硬貨の金属と同等か若しくはそれよりも小さい硬度を有している。
【００１２】
上記印刷物１は図１に示す如く見た目には全面平網状であり画像の区別はつかないが、表面を硬貨で擦ると、図３に示す如く画像を構成する領域の網点３ａのみが黒色化して画像が明瞭に視認し得る状態となった。
【００１３】
そして、網点のサイズは印刷できる範囲で小さくかつ現れた文字や絵柄が判別できる範囲でできるだけ間隔をあけて網点を形成するようにしたので、擦る前の画像が判別し難くなっている。
【００１４】
【発明の効果】
以上説明したように、本発明の特殊印刷物は、基材上に均一な網点で構成される平網を設けた印刷物であって、文字や絵柄の画像を構成する領域の網点を硬貨の金属よりも硬度の大きい材料を含むインキ組成物で印刷するとともに、それ以外の領域の網点を硬貨の金属と同等か若しくはそれよりも小さい硬度を有する材料を含むインキ組成物で印刷し、硬貨で擦ることにより画像部分の網点が着色化して画像が視認できるようにするとともに、印刷できる範囲で小さくかつ現れた画像が判別できる範囲で間隔をあけて網点を形成したものであるので、銀インキを用いてシルクスクリーン印刷により隠蔽層を形成する必要がなく低コストで効率良く製造できる上に、硬貨で擦る前にあっては見た目に全面平網であって画像の区別がつかず、硬貨で擦ることによってはじめて画像部分の網点が黒色に変化して明瞭に認識できる状態となることから、擦る前に画像が視認できるのが好ましくない各種くじ類、玩具等に広く利用することができる。
【図面の簡単な説明】
【図１】本発明の一実施例としての特殊印刷物の一部分を示す平面図である。
【図２】画像を構成する領域を一点鎖線で示した平面図である。
【図３】特殊印刷物を硬貨で擦った状態を示す平面図である。
