Fluoropolymer containing ethylenically unsaturated groups, and curable resin compositions and antireflection coatings, made by using the same

摘要

An ethylenically unsaturated group-containing fluoropolymer, which is obtained by reacting a compound containing one isocyanate group and at least one ethylenically unsaturated group, and a hydroxyl group-containing fluoropolymer at an isocyanate group/hydroxyl group molar ratio of 1.1 to 1.9. According to the present invention, an ethylenically unsaturated group-containing fluoropolymer having superior antiscratching property, coating property and durability, as well as a curable resin composition and an antireflection film using the same can be provided.
