Patent ID: 10996377

Abstract:
The method for producing an optical member of the present invention includes: a step (1) of applying a lower layer resin and an upper layer resin; a step (2) of pressing a die against the lower layer resin and the upper layer resin from the upper layer resin side, so as to form a resin layer including an uneven structure on a surface thereof; and a step (3) of curing the resin layer to form the polymer layer, wherein the lower layer resin contains an amide group, the lower layer resin has an amide group concentration of 1.5 mmol/g or more and less than 5 mmol/g, and the polymer layer has a minimum storage modulus E′ of 1×108 Pa or higher and 1×109 Pa or lower at a bottom temperature of 110° C. or higher and 210° C. or lower.
