PRIMER-FORMING COMPOSITION, PLASTIC LENS HAVING PRIMER LAYER EMPLOYING THE COMPOSITION, AND METHOD FOR MANUFACTURING THE PLASTIC LENS

摘要

PPROBLEM TO BE SOLVED: To provide a primer composition forming a primer layer which achieves excellent adhesion of a plastic lens substrate and a hard coat and can reliably realize improvement in impact resistance of a lens while it is a primer layer having a high refractive index, and to provide a method for preparing the same. PSOLUTION: The primer-forming composition comprises (A) polyurethane resin particles, (B) a urethane-forming monomer and/or oligomer, and (C) oxide microparticles. A method for manufacturing a plastic lens is also provided. The method comprises; forming a primer layer using the primer-forming composition on at least one surface of a plastic substrate; and forming a hard coat layer over the primer layer to obtain a plastic lens sequentially comprising a primer layer and a hard coat layer on at least one surface of a plastic substrate.
