Paper Abstract

Nitrile-containing polymers are used to prepare light-absorbing coatings for liquid crystal displays. The coatings, initially transparent to visible light, develop intense color when heated. Optical densities greater than 2 across the visible spectrum were obtained in 1 gm films of a copolymer of acrylonitrile and methyl acrylate baked at 400 C, and in 1 p.m coatings of the same polymer doped with a cyan dye and baked at 250 C. The films were etched in an oxygen plasma to form a black matrix for a three color filter array.
