Abstract:
(EN) This optical component comprises a light-transmitting member and an anti-fogging coating film that is formed on a surface of a light-transmitting member or is formed on a functional coating film formed on said surface. The anti-fogging coating film is formed by applying an anti-fogging agent, which contains a polymer obtained by copolymerizing raw materials including an anchor material and a hydrophilic base material, to the surface or the functional coating film. The hydrophilic base material has a betaine structure. The thickness of the anti-fogging coating film is 0.2-1.5 μm. It is preferable for the anti-fogging coating film to be disposed on the functional coating film, and for the functional coating film to be an anti-reflection coating film.
(FR) La présente invention concerne un élément optique comprenant un organe de transmission de lumière et un film de revêtement antibuée qui est formé sur une surface d'un organe de transmission de lumière ou sur un film de revêtement fonctionnel formé sur ladite surface. Le film de revêtement antibuée est formé par application d'un agent antibuée, qui contient un polymère obtenu par copolymérisation de matières premières comprenant un matériau d'ancrage et un matériau de base hydrophile, sur la surface ou sur le film de revêtement fonctionnel. Le matériau de base hydrophile présente une structure de bétaïne. L'épaisseur du film de revêtement antibuée va de 0,2 à 1,5 µm. Il est préférable que le film de revêtement antibuée soit disposé sur le film de revêtement fonctionnel, et que le film de revêtement fonctionnel soit un film de revêtement antireflet.
(JA) 光学部品は、透光部材と、前記透光部材の表面上に、または、前記表面上に形成された機能性被膜上に形成された防曇被膜と、を備える。前記防曇被膜は、アンカー材料と、親水基材料とを含む原料が共重合したポリマーを含む防曇剤を前記表面上に、または、前記機能性被膜上に付与して形成されたものである。親水基材料は、ベタイン構造を有する。前記防曇被膜の厚さは、0.2μm以上1.5μm以下である。好ましくは、前記防曇被膜は、前記機能性被膜上に位置し、前記機能性被膜は反射防止被膜である。
