An object of the present invention is to provide a primer coating layer having excellent impact resistance, scratch resistance, adhesion, and high refractive index in an optical substrate having a high refractive index, in particular, a plastic lens, without causing appearance defects such as nonuniformity and opacity, The present invention provides a primer composition for an optical article which can be formed without being influenced and which has good storage stability. The primer composition for an optical article comprises a urethane resin having a skeleton derived from a polycarbonate, a polyester resin, fine particles of an inorganic oxide and water, and may contain a water-soluble organic solvent if necessary. |
