ABSTRACT:
A resinous composition for preparing opaque films which consists of a film-forming material in which there is dispersed discrete cellular particles. Each particle is composed of non-opaque, film-forming material, such as acrylic resins, and contains therein one or more cells, having an average diameter of less than 15 microns, which serve to scatter incident light rays. The particulate matter is easily dispersed in the film-forming material by means of conventional mixing procedures.
