PROBLEM TO BE SOLVED: To provide a polarizing plastic lens capable of suppressing peeling of a polarizing film from a lens body and a manufacturing method thereof, a polarizing plastic film capable of suppressing peeling of a polarizing film from a film body, and a manufacturing method thereof. A polarizing plastic lens 11 is formed in a gently curved shape, and a pair of lens bodies 12 having different thicknesses are provided on both surfaces of a polarizing film 13 formed of a polyvinyl alcohol resin as a resin having a hydroxyl group. Configured. The lens body 12 is obtained by polymerizing a polymerization raw material containing a compound having an isocyanato group or an isothiocyanato group as one of the main components. In the polarizing plastic lens 11, the isocyanato group or isothiocyanate group contained in the resin forming the lens body 12 and the hydroxyl group contained in the resin forming the polarizing film 13 are bonded by a urethane bond or a thiourethane bond. It is formed in the state. [Selection] Figure 1 |
