摘要：
A matte coat having a first major surface, the matte coat comprising a first layer defining the first major face of the matte coat and comprising a polymeric matrix and a plurality of forming bodies entrained therein, wherein index of refraction of the forming bodies is similar to that of the polymeric matrix and the first major surface has a plurality of protuberances corresponding to forming bodies entrained within. Also, optical assemblies comprising such matte coats and methods for making such matte coats.
