Description
特許文献2には、レーザー誘導弾に対して有効な防御手段が可能なレーザー照射検出装置が開示されているが、軍事目的の極めて高価かつ大がかりな装置であり、到底一般の用途に適用できるものではなかった。
以下に本発明を詳述する。

上記ポリビニルアセタール樹脂のアセタール化度の好ましい下限は40モル%、好ましい上限は85モル%であり、より好ましい下限は60モル%、より好ましい上限は75モル%である。
なお、上記アセタール化度及び水酸基量は、例えば、JIS K6728「ポリビニルブチラール試験方法」に準拠して測定できる。
上記ポリビニルアルコールの重合度の好ましい下限は500、好ましい上限は4000である。上記ポリビニルアルコールの重合度が500以上であると、得られる発光シートを透明板との積層体としたときに耐貫通性が高くなる。上記ポリビニルアルコールの重合度が4000以下であると、発光シートの成形が容易になる。上記ポリビニルアルコールの重合度のより好ましい下限は1000、より好ましい上限は3600である。
ランタノイド錯体のなかでも、ハロゲン原子を含む多座配位子を有するランタノイド錯体はレーザー光を照射することにより高い発光強度で発光する。上記ハロゲン原子を含む多座配位子を有するランタノイド錯体としては、ハロゲン原子を含む二座配位子を有するランタノイド錯体、ハロゲン原子を含む三座配位子を有するランタノイド錯体、ハロゲン原子を含む四座配位子を有するランタノイド錯体、ハロゲン原子を含む五座配位子を有するランタノイド錯体、ハロゲン原子を含む六座配位子を有するランタノイド錯体等が挙げられる。

これらは単独で用いてもよく、2種以上を用いてもよい。
上記発光シートの透明性がより一層高くなることから、xは1又は2であることが好ましく、ベンゼン環の2位又は5位に水酸基を有することがより好ましく、ベンゼン環の2位及び5位に水酸基を有することが更に好ましい。

上記炭化水素基はアルキル基であることが好ましい。
なかでも、コントラストがより一層高い画像を表示できることから、上記一般式(1)で表される構造を有する化合物はジエチル-2,5-ジヒドロキシルテレフタレート(Aldrich社製「2,5-ジヒドロキシテレフタル酸ジエチル」)であることが好ましい。
上記R2の有機基は炭化水素基であることが好ましく、炭素数が1~10の炭化水素基であることがより好ましく、炭素数が1~5の炭化水素基であることが更に好ましく、炭素数が1~3の炭化水素基であることが特に好ましい。

上記可塑剤は特に限定されず、例えば、一塩基性有機酸エステル、多塩基性有機酸エステル等の有機エステル可塑剤、有機リン酸可塑剤、有機亜リン酸可塑剤等のリン酸可塑剤等が挙げられる。上記可塑剤は液状可塑剤であることが好ましい。

そこで、上記発光シートに含まれるカリウム、ナトリウム及びマグネシウムの合計の含有量は50ppm以下であることが好ましい。カリウム、ナトリウム及びマグネシウムの合計の含有量を50ppm以下とすることにより、発光材料の発光性が低下するのを防止することができる。

本発明のレーザー光検知具の態様は特に限定されないが、透明板と発光シートとの積層体構造を有することが好ましい。上記積層体構造とすることにより取り扱い性が向上し、種々の用途への適用が可能となる。なかでも、一対の透明板の間に上記発光シートが積層されている構造(合わせガラス構造)を有することが好ましい。
上記透明板として、2種類以上の透明板を用いてもよい。また、上記透明板として、2種以上の厚さの異なる透明板を用いてもよい。
上記検知部としては特に限定されず、例えば、上記発光シートの全面の画像を撮影し、得られた画像上で発光シートに発光が認められた場合に、シグナルを発信する装置等が挙げられる。
この際、レーザー光検知具の一方の側から照射されたレーザー光のみを検知し、他方の側から照射されたレーザー光は検知しない装置とすることが好ましい。このような装置とすることにより、例えば、本発明のレーザー光検知具を合わせガラス構造として、車やバイク、飛行機等の車両用窓ガラスとして用いた場合に、外部から照射されたレーザー光を検知できる一方、ヘッドアップディスプレイ等の表示のために内側から照射されたレーザー光を検知してしまうのを防止することができる。
上記報知部は、検知部がレーザー光を検出しなくなったときに報知を停止することが好ましい。これにより、レーザー光の照射が持続している間はそれを検知することができ、照射が止んだときにはそれを検知することができる。
