ABSTRACT:
A reflection preventing layered product is provided by laminating a high refractive index layer and a low refractive index layer, which has a refractive index lower than that of the high refractive index layer, in that order on a transparent plastic film, directly or through another layer. The low refractive index layer has a surface resistance of 1.0×1010ohm/square inch or less, a total light remittance of 94% or more, and a refractive index of 1.25-1.37. An optical member provided with the reflection preventing layered product is also provided. This optical member is preferably a polarizing plate with reflection preventing function used for a liquid crystal display. The reflection preventing layered product excels in transparency, mechanical strength, antistaticity, and reflection preventing characteristics.
