OPTICAL MEMBER AND WINDOW MATERIAL
PROBLEM TO BE SOLVED: To provide an optical member which is improved in workability of water sticking to a stuck body such as a window pane and further capable of presenting a high glass scattering prevention performance over long-time use.SOLUTION: An optical member comprises: an optical layer consisting of a first optical layer including a surface in an uneven shape, a reflection layer disposed on the surface in the uneven shape of the first optical layer and a second optical layer disposed on the reflection layer; a first transparent substrate disposed in the optical layer at a side of the first optical layer; and a second transparent substrate disposed in the optical layer at a side of the second optical layer. The reflection layer reflects near infrared light, and the first and second transparent substrates consist of the same material. Total thickness is equal to or less than 125 μm, a breaking strength is equal to or more than 100 N, and both a breaking extension before a weather resistance test and a breaking extension after the weather resistance test are equal to or more than 60%.SELECTED DRAWING: Figure 1A
【課題】窓ガラス等の被着体に対する水貼り施工性に優れる上、長期の使用に亘って高いガラス飛散防止性能を発揮することができる光学部材を提供する【解決手段】光学部材は、凹凸形状の面を有する第１の光学層、前記第１の光学層の凹凸形状の面上に配置された反射層、及び前記反射層上に配置された第２の光学層からなる光学層と、前記光学層の前記第１の光学層側に配置された第１の透明基材と、前記光学層の前記第２の光学層側に配置された第２の透明基材と、を備え、前記反射層は、近赤外光を反射し、前記第１の透明基材及び前記第２の透明基材は、同一の材料からなり、総厚が、１２５μｍ以下であり、破断強度が、１００Ｎ以上であり、耐候性試験前の破断伸び及び耐候性試験後の破断伸びが、いずれも６０％以上である。【選択図】図１Ａ
