Abstract

A primer coating composition is provided for an optical article capable of forming a coating layer having excellent impact resistance, abrasion resistance, adhesion and high refractive index to an optical base material, having high refractive index, specifically a plastic lens without occurrence of poor appearance such as ununiformity, cloudiness, etc. and regardless of the materials of the plastic lens. A primer composition for an optical article may comprises urethane resin having a polycarbonate-derived skeleton, polyester resin, inorganic oxide fine particles and water, and water-soluble organic solvent, if necessary.
