发明名称 Substrate for optical recording media and information records
摘要 A major surface of a disc-shaped plastic base is coated with two or more nonconformal coating layers with a solvent barrier layer interposed between said coating layers. The nonconformal coating layers fill in surface imperfections of the base while the solvent barrier layers allow an efficient stacking of said coating layers to yield a surface suitable for optical recording.
