Method for producing product having uneven microstructure on surface thereof, mold release treatment method, and active energy ray curable resin composition for mold surface release treatment

A method for producing a product having an uneven microstructure on a surface thereof, the producing method comprising the following steps (I)-(II):

• step (I) supplying an active energy ray curable resin composition for a mold surface release treatment between a substrate and a mold having an uneven microstructure on a surface thereof, curing the active energy ray curable resin composition for the mold surface release treatment by irradiation with an active energy ray, and peeling off the substrate with a cured article of the active energy ray curable resin composition from the surface of the mold, so as to perform a release treatment to the surface of the mold;
• and
• step (II), after the step (I), supplying an active energy ray curable resin composition for shaping, which is different to the active energy ray curable resin composition for the mold surface release treatment, between the substrate and the mold, the surface of which has been treated by the release treatment, curing the active energy ray curable resin composition for shaping by irradiation with an active energy ray, and peeling off the substrate with a cured article of the active energy ray curable resin composition form the surface of the mold, so as to obtain the product having the uneven microstructure, which corresponds to the uneven microstructure of the mold, on the surface thereof.
