Abstract
【解決手段】下地基板3に金属層L1を形成し、その上に屈折率nが異なる薄膜層L2〜L8を積層した干渉薄膜層Lsを設ける。干渉薄膜層Lsの表面に透明な保護層L9を形成する。干渉薄膜層Lsが反射光に波長依存性のある強度変調を与え、また薄膜層L2,L4,L8がもつ光吸収により反射光量は低く抑えられ、独特の色合いをもった外観色が得られる。屈折率n、消衰係数k,虚数iを用いて薄膜層L2,L4,L8の複素屈折率Nを「N=n−ik」としたとき、「1.36≦n≦3.5」、「0.1≦k≦6」が満たされる。
【選択図】図1
Description
1.36≦n≦3.5
0.1≦k≦6
を満たすようにするのが実用的である。屈折率nが上記下限値を下回ると波長選択性のある分光反射特性が得にくくなり、所望の特性を得るには薄膜の積層数が増えて製造コストが高くなる振りがある。逆に、屈折率nとして上限値を上回るような値を得ようとすると、その成膜条件を安定に保つことが難しく、屈折率nの値だけでなく消衰係数kの値も不安定になって工業的な製造には不向きとなる。また、消衰係数kが上記範囲から外れると反射光量の制御が難しくなり、沈んだ色合いの適度な強度の反射光が得にくくなる。
