ABSTRACT:
Process for forming an optically transparent polymeric protective layer for an information disc. The disc is placed in a stationary horizontal position and a liquid radiation curable coating is applied to the surface of the disc from an applicator disposed above the disc. Coating of the disc is accomplished by equally spaced sequential movement of an applicator which is on a plane parallel to the surface of the stationary disc. The liquid coating is then allowed to spread evenly across the disc surface and is thereafter cured by means of radiation.
