ABSTRACT:
A composition for use in refinishing optical discs comprises a mixture of volatile organic solvents having solubility parameters within a defined range, a chemically reactive nonvolatile binder, insoluble particulate material for polishing, and an immiscible phase forming an emulsion with the other components, thereby holding the particulate matter in suspension. Anionic surfactants are added to improve wetting, along with a conventional wetting agent. The mixture of solvents promotes reflow of the disc surface, while the binder fills in deformations and provides a permanent protective coating.
