CURABLE COMPOSITION, FINE RUGGED STRUCTURE, DECORATIVE SHEET, DECORATIVE RESIN MOLDED ARTICLE, AND PRODUCTION METHOD OF DECORATIVE RESIN MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a fine rugged structure having excellent antireflection performance and suitable for three-dimensional molding, a decorative sheet, a curable composition that gives a decorative resin molded article including the decorative sheet, and a production method of a decorative resin molded article. ! SOLUTION: The curable composition for forming a fine rugged structure provides a cured product thereof having an elastic modulus of 50 MPa or more at 25°C and an elastic modulus of 30 MPa or less at 80°C. The cured product of the curable composition preferably has a toughness of 1 kJ/m2 or more in a tensile test at 80°C. The production method of a decorative resin molded article includes a step (A1) of heating a decorative sheet and pressing the heated decorative sheet against a mold by evacuating or supplying compressed air to obtain a decorative resin molded article having a fine rugged structure on its surface. !
