Abstract

A light curable anti-glare coating liquid composition for coating onto a transparent substrate, the composition comprising a dispersion of nanoparticles of a mineral oxide suspended in a mixture of an acrylate-functional resin that is compatible with the nanoparticle dispersion, compatible solvent, incompatible solvent that has a lower volatility than the compatible solvent, and a surfactant that has poor or limited compatibility with the dispersion.
