titleOfInvention |
Eyeglass lens, composition for primer layer formation, and method for manufacturing eyeglass lens |
abstract |
This eyeglass lens is outstanding in anti-crazing properties, impact resistance properties, and adhesion. The present invention comprises: a lens substrate; a primer layer disposed on the lens substrate; and at least one layer that is disposed on the primer layer and that is selected from the group consisting of a hard-coat layer and a reflection-preventing layer. The primer layer contains a polycarbonate-based polyurethane resin and inorganic oxide particles. The tensile strength of the polycarbonate-based polyurethane resin is over 40 N/mm2. The expansion rate of the polycarbonate-based polyurethane resin is at least 300%, and the inorganic oxide particle content is 10-40% by volume with respect to the total volume of the primer layer. |
