<P>PROBLEM TO BE SOLVED: To provide a production method for a moth-eye film which surely forms a fine moth-eye structure even if using no mold. <P>SOLUTION: The production method includes an applying step of applying a coating liquid for a moth-eye layer onto a transparent base-material film, a moth-eye layer forming step of drying the coating liquid for the moth-eye layer to form the moth-eye structure, and a moth-eye layer curing step of curing the moth-eye layer by irradiation of an active-energy ray. The moth-eye layer has 60-97 wt.% of an active-energy ray curing type resin, 1-35 wt.% of a polymer component and 1-10 wt.% of a photopolymerization initiator, and also the sum of the active-energy ray curing type resin, the polymer component and the photopolymerization initiator is 99-100 wt.%. In the moth-eye layer forming step, far-infrared containing any of wavelengths of 2-20 μm is radiated to the coating liquid for the moth-eye layer to dry it. <P>COPYRIGHT: (C)2013,JPO&INPIT |
