<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition which enables a nano convex/concave structure to be formed, the nano convex/concave structure having good water repellency and high durability even under conditions of accelerated weatherability testing, and to provide a nano convex/concave structure and a water-repellent article each using the active energy ray-curable resin composition. <P>SOLUTION: The active energy ray-curable resin composition contains: a monomer component with polymerization reactivity including 50-90 pts.mass of a specific polyfunctional monomer (A), 5-49.5 pts.mass of a fluorine-containing monomer (B) represented by formula (1) and compatible with the polyfunctional monomer (A), and 0.5-10 pts.mass of a specific monofunctional fluorine-containing monomer (C); and 0.01-10 pts.mass of an active energy ray polymerization initiator relative to 100 pts.mass of the monomer component with polymerization reactivity, wherein the mass ratio ((C)/(B)) between the fluorine-containing monomer (B) and the monofunctional fluorine-containing monomer (C) is ≤0.12. (In the formula, R<SP POS="POST">f</SP>represents one of formulae (2) to (6), X<SP POS="POST">1</SP>and X<SP POS="POST">2</SP>are the same or different and represent CH<SB POS="POST">2</SB>=C(R<SP POS="POST">1</SP>)-C(O)-O-, and R<SP POS="POST">1</SP>represents H or CH<SB POS="POST">3</SB>). <P>COPYRIGHT: (C)2013,JPO&INPIT |
