| description | To provide a shading film which does not allow occurrence of crack in lens even if the lens is composed of a base material likely to be subjected to stress and even when subjected to severe thermal shock, nor allow occurrence of bleed-out under a hot and humid environment, and which has high inner surface antireflection performance.SOLUTION: The shading film includes an aggregate of inorganic particles in d-ray refractive index of 2.0 or greater, a coloring agent, a resin and a plasticizer. An average particle diameter of the aggregate is 250 nm or less, and the plasticizer has a pour point of -50°C or below and a boiling point of 200°C to 450°C inclusive.SELECTED DRAWING: None
【課題】応力がかかりやすい基材構成で過酷な熱衝撃においてもレンズの割れが発生せず、且つ高温高湿下でのブリードアウトが発生せず、さらに内面反射防止性能が高い遮光膜及を提供する。【解決手段】ｄ線屈折率が２．０以上の無機粒子の凝集体と、着色剤と、樹脂と、可塑剤とを有し、凝集体の平均粒子径は２５０ｎｍ以下であり、可塑剤は、流動点が－５０℃以下、かつ沸点が２００℃以上４５０℃以下である遮光膜。【選択図】なし |
