Document Type and Number:
WIPO Patent Application WO/2017/141781
Kind Code:
A1
Abstract:
The present invention provides an optical member having excellent abrasion resistance. The optical member according to the present invention is provided with a polymer layer having, on a surface, an uneven structure in which a plurality of projected parts are provided at a pitch equal to or smaller than the wavelength of visible light. The polymer layer is made of the cured product of an acrylic polymer composition. The acrylic polymer composition contains: a polyfunctional acrylate and a monofunctional acrylate in a total amount of 60-90 parts by weight; and cross-linkable organic fine particles in an amount of 10-40 parts by weight, each having a radical polymerizable double bond on the surface.
