ABSTRACT:
A two-layer antireflective coating composition stacked on a substrate consisting of allyl diglycol carbonate polymer (CR-39) or glass and comprising a bottom layer containing less than 10% by weight of titanium dioxide equivalent weight and a titanium-free top layer containing polysiloxane resin; and a process for preparing said antireflective coating with improved adhesion on a substrate consisting of allyl diglycol carbonate polymer (CR-39) or glass. The thicknesses of each of said coating layers is in accordance with preselected equations, and the refractive indices of a said coating layers satisfy the following requirements:
