- the pitch is the same. This is described later because when the first pitch (P 1 ) and the second pitch (P 2 ) are the same, the first element (11) and the second element (21) always overlap at a constant interval.

It is formed in a size range of / 10. If the image element width (W 2 ) and pixel height (W 2 ) of the second element (21) are larger than 9/10 with respect to the first pitch (P 1 ), the latent This is because the second element (21) overlaps the image element (12A), the background element (13A), and the contour element (14A), so that contrast cannot be obtained and the latent image cannot be observed.
- the line width (W 2 ) and pixel height (W 2 ) of the second element (21) are smaller than 10 ⁇ m, the first element (11) and the second element (21) overlap. This is because the visibility of the latent image is reduced because the area is small.

本発明は、基材に形成された凹形状又は凸形状で成る第1の模様の上に、基材と異なる色で成る第2の模様が形成された潜像模様形成体であって、第1の模様と第2の模様の配置によって、斜めから観察したときに、第2の模様の色が観察される部分と第2の模様の色が観察されない部分が生じ、潜像が観察できるものである。第1の実施の形態は、斜めから観察すると、図1に示す潜像の図柄の左右方向の輪郭が、潜像と背景に対して異なる色で観察できる潜像模様形成体(2)である。
第1の模様(10)は、図3に示すように、基材(1)に、第1の要素(11)が第1の方向に複数配置されて成る。なお、本発明において、「第1の方向」とは、基材(1)に第1の要素(11)が配置される方向のことである。
直線で構成される第1の要素(11)が複数配置された例を、図6(a)に示す。また、破線による画線で構成される第1の要素(11)が複数配置された例を、図6(b)に示す。また、波線による画線で構成される第1の要素(11)が複数配置された例を、図6(c)に示す。また、画線内に図柄が付与された画線で構成される第1の要素(11)が複数配置された例を、図6(d)に示す。
画素の幅(X1)は、1000μm以下の範囲で形成される。これは、画素によって第1の要素(11)が構成されたとき、肉眼で観察したときに画素の形状が観察され難い大きさが、1000μm以下であるからである。
潜像要素(12A)は、背景要素(13A)に対して、第1のピッチ(P1)より小さい範囲で位相が異なるように配置される。すなわち、潜像要素(12A)と背景要素(13A)は、互いに対応する関係で配置される。なお、潜像要素(12A)は、図8(a)に示すように、背景要素(13A)に対して上側に位相を異ならせてもよく、また、図8(b)に示すように、潜像要素(12A)を背景要素(13A)に対して下側に位相を異ならせてもよい。
輪郭要素(14A)は、背景要素(13A)及び潜像要素(12A)と略平行に、かつ、背景要素(13A)の位相及び潜像要素(12A)の位相と異なる位相に配置される。略平行の範囲は、背景要素(13A)及び潜像要素(12A)に対して5度以内の角度である。5度以内であれば、輪郭部(14)の視認性に影響なく、後述する第2の要素(21)との位置合わせにおいて、許容をもたせることができる。なお、輪郭要素(14A)は、図8に示すように、背景要素(13A)の位相と潜像要素(12A)の位相の間の位相に配置、図10(a)に示すように、潜像要素(12A)の上側の位相に配置又は図10(b)に示すように、背景要素(13A)の下側の位相に配置のいずれでもよい。ただし、図10に示すように、輪郭要素(14A)が配置される場合、輪郭要素(14A)は、点線の枠を越えて隣り合う各要素を越えない範囲で配置される。なお、輪郭要素(14A)が配置される位相は、潜像要素(12A)が、背景要素(13A)に対して下側に位相を異ならせる場合も同様である。
凹形状又は凸形状の第1の要素(11)の形成方法としては、エンボス、すき入れ、レーザ加工、インキによる印刷等を用いることができる。なお、すき入れ、レーザ加工、インキによって第1の要素(11)を形成する場合は、第2の要素(21)を形成する前に、第1の要素(11)を形成する必要がある。これは、第2の要素(21)を形成した後に、第1の要素(11)を形成すると、凹形状又は凸形状の表面に第2の要素(21)が形成できなくなるからである。
第2の模様(20)は、図13に示すように、基材(1)に、第2の要素(21)が第2の方向に複数配置されて成る。なお、第2の要素(21)は、図6及び図7に示す第1の要素(11)と同様に、画線又は複数の画素で構成される。したがって、第1の要素(11)の構成で説明したところは省略することとするが、第2の要素(21)に対しては、第2のピッチ(P2)、画線の幅(W2)、画素の高さ(W2)、画素の幅(X2)及び画素のピッチ(p2)とする。なお、第2の要素(21)は、第1の要素(11)と異なる画線又は画素で形成してもよい。また、特許第3368327号公報記載の画線構成とし、第2の要素(21)において、一本の画線で構成される部分と三本の画線で構成される部分を形成し、一本の画線で構成される部分と三本の画線で構成される部分の単位長さ辺りの画線の面積率を同じにして形成してもよい。
以降、第1の模様(10)と第2の模様(20)の配置と観察される潜像について説明するが、まず、本発明の潜像の観察原理について説明する。
一方、観察点(L2)のように、基材(1)を斜めから観察した場合には、凸形状の頂点(Q)を境として、手前側となる凸形状の表面では観察することができるが、奥側の表面は凸形状の裏側にあたり、死角となることから観察することができない。また、基材(1)の平らな部分は、凸形状の死角となって基本的に観察することができないが、特に、凸形状の頂点(Q)を境として、手前側となる凸形状の表面に近い側の部分は、第1の要素(11)の形状や第1のピッチ(P1)及び画線の幅(W1)によって、観察されることもある。また、凸形状の頂点(Q)を境として、手前側となる凸形状の表面において観察できる範囲も、第1の要素(11)の形状、第1のピッチ(P1)及び画線の幅(W1)によって、若干の差はあるが、以降の説明では、凸形状の頂点(Q)を境として、手前側となる凸形状の表面のみが観察されるものとし、基材(1)を斜めから観察したときに、凸形状の頂点(Q)を境として、手前側となる凸形状の表面のことを「観察部(V)」、基材(1)を斜めから観察したときに、凸形状の頂点(Q)を境として、奥側となる凸形状の表面及び基材(1)の平らな部分のことを「非観察部(V’)」として説明する。なお、図15(b)は、図15(a)に示すX-X線の断面図であり、図15(b)に示す観察部(V)及び非観察部(V’)は、X-X線上のものであるが、実際には、図15(a)及び(b)に示すように、一つの第1の要素(11)において、所定の位置における凸形状の頂点(Q)を全体に渡って結ぶ線、すなわちZ-Z線を境として観察部(V)と非観察部(V’)に区分けされる。
第2の実施の形態は、斜めから観察すると、潜像の図柄の左右方向の輪郭が、潜像部又は背景部と同じ濃度で2重に観察できる潜像模様形成体(2)であり、図25は、潜像部と同じ濃度で2重の輪郭が観察できる潜像模様形成体(2)を示している。第2の実施の形態の潜像模様形成体(2)について、第1の実施の形態と異なる点を、図25~図38を用いて説明する。
第2の実施の形態における第1の模様(10)を図27に示す。第2の実施の形態において、第1の模様(10)の潜像部(12)と背景部(13)の構成は、第1の実施の形態と同様であり、輪郭部(14)の構成が、第1の実施の形態と異なる。そこで、輪郭部(14)の構成について以下に説明する。
輪郭部(14)は、図27(b)の拡大図に示すように、潜像要素(12A)と同じ位相に配置された輪郭要素(14A)と、潜像要素(12A)と輪郭要素(14A)の間に、潜像要素(12A)及び輪郭要素(14A)に対して、異なる位相に配置された第1の要素(以下、「輪郭補助要素(14B)」と呼ぶ。)から成る。
以降、第1の模様(10)と第2の模様(20)の配置と観察される画像について説明する。なお、第1のピッチ(P1)と第2のピッチ(P2)が同じピッチで配置されて成る第1の模様(10)と第2の模様(20)の配置と観察される図柄について説明する。第2の実施の形態においては、第5の配置から説明する。
第3の実施の形態は、斜めから観察すると図39に示すように、潜像の図柄の上下方向の輪郭が観察できる潜像模様形成体(2)である。第3の実施の形態の潜像模様形成体(2)について、第1の実施の形態及び第2の実施の形態と異なる点を、図39~図59を用いて説明する。
第3の実施の形態における第1の模様(10)を図41に示す。第3の実施の形態において、第1の模様(10)の潜像部(12)と背景部(13)の構成は、第1の実施の形態と同様である。第1の実施の形態と第2の実施の形態は、潜像の図柄の左右方向の輪郭が観察できるのに対して、第3の実施の形態は、潜像の図柄の上下方向の輪郭が観察できるものであり、第1の模様(10)の輪郭部(14)の構成が異なる。そこで、輪郭部(14)の構成について説明する。
本発明において、潜像の図柄の上下方向の輪郭が観察される輪郭部(14)の構成は、3通りあり、それぞれの構成について、図を用いて説明する。なお、輪郭部(14)の構成の説明で用いる図は、図41に示す第1の模様(10)において、太線の枠で囲まれた部分に相当する部分である。
以降、第1の模様(10)と第2の模様(20)の配置と観察される画像について、第3の実施の形態の輪郭部(14)の構成ごとに説明する。なお、第1のピッチ(P1)と第2のピッチ(P1)が同じピッチで配置されて成る第1の模様(10)と第2の模様(20)の配置と観察される図柄について説明する。第3の実施の形態においては、第10の配置から説明する。
図57(a)は、潜像隣接輪郭要素(15A)が、潜像要素(12A)の最外線から第1のピッチ(P1)の位置より下側に配置され、背景隣接輪郭要素(15B)が、潜像要素(12A)の最外線から第1のピッチ(P1)の2倍の位置より上側に配置され、第13の配置に対して、さらに、背景隣接輪郭要素(15B)の観察部(V)に第2の要素(21)が重ならない状態を示している。また、各要素の観察部(V)に重なる第2の要素(21)の面積率が、潜像隣接輪郭要素(15A)、潜像要素(12A)、背景要素(13A)の順に小さくなる状態を示している。
第3の模様(31)は、図72に示すように、基材(1)に、第3の要素(31)が第3の方向に複数配置されて成る。第3の方向は、第1の方向と同じ方向でもよいし、異なる方向でもよい。その他の構成については、第2の模様(20)と同様である。
実施例1は、第1の実施の形態の構成で作成された潜像模様形成体(2)である。実施例1の潜像模様形成体(2)について、第1の実施の形態で説明した図面を用いて説明する。
実施例2は、実施例1に対して異なる点のみを説明する。実施例2は、凹版インキを印刷して凸形状の第1の要素(11)を形成し、また、第2の要素(21)を画素で構成した潜像模様形成(2)である。
実施例3は、実施例1に対して異なる点のみを説明する。実施例3は、レーザ加工によって凹形状の第1の要素(11)を形成し、第1の模様(10)の輪郭部(14)は、輪郭要素(14A1)と輪郭要素(14A2)を二つ配置して成り、さらに第3の模様(30)を形成したものである。

実施例7は、実施例6に対して異なる点のみを説明する。実施例7は、実施例6から、さらに、第3の模様(30)を形成した潜像模様形成体(2)である。
実施例8は、実施例4に対して異なる点のみを説明する。実施例8は、第2の実施の形態と第3の実施の形態を複合的に施した潜像模様形成体(2)である。
実施例9は、実施例6に対して異なる点のみを説明する。実施例9は実施例6に対して第2の模様(20)を第1の模様(10)に対して1度傾斜させて配置したものである。
