Title:
FILM FOR THREE-DIMENSIONAL MOLDING, THREE-DIMENSIONAL STRUCTURE HAVING UNEVEN STRUCTURE, PRODUCTION METHOD THEREFOR, AND PRODUCTION METHOD FOR ELECTROFORMING MOLD
Document Type and Number:
WIPO Patent Application WO/2021/079740
Kind Code:
A1
Abstract:
Provided are: a film for three-dimensional molding, capable of applying a fine uneven structure to the surface of a three-dimensional structure, even if the three-dimensional structure is large, and providing excellent precision to the applied fine uneven structure; a three-dimensional structure having an uneven structure and using the film for three-dimensional molding; a production method therefor; and a production method for an electroforming mold using the three-dimensional structure having an uneven structure. The film for three-dimensional molding has: a ductile film; a ductile cured layer positioned upon a first surface of the ductile film, comprising a cured product of a curable resin composition, and having an uneven structure having an average surface pitch of 50 nm–8 µm; and an inorganic layer formed that follows the uneven structure. The film for three-dimensional molding has an elongation at break of at least 10% at 110°C. The inorganic layer comprises at least one type of inorganic material selected from the group consisting of Au, Pt, Pd, Ni, NiP, Cr, and W.
