FLUORINATED UNSATURATED COMPOUNDS, FLUOROPOLYMERS, AND CURABLE COMPOSITIONS CONTAINING BOTH

摘要

The invention provides fluorinated unsaturated compounds which can realize high-hardness films by photopolymerization photocuring photopolymerizable compositions containing the same antireflection coatings which are improved in anti- reflection effect, mar resistance, and wear resistance while keeping the stainproofing performance and antireflection articles covered with such coatings, the fluorinated unsaturated compounds being represented by the general formula M: wherein X1 and X2 may be the same or different and are each H or F X3 is H, F, CH3, or CF3 X4 and X5 may be the same or different and are each H, F, or CF3 a, b, and c may be the same or different and are each 0 or 1 d is an integer of 1 to 4 and Rf is a fluorinated alkyl group having 18 to 200 carbon atoms and ether linkages, which is characterized by containing six or more repeating units represented by the general formula 1: wherein X6 is F or H.
