Abstract
Abstract A copolymer comprising (a) units of a fluorine-containing acrylic monomer having a general formula <IMAGE> wherein X is F or CF3, Y is H or CH3, n is an integer of 2 to 7, and (b) units of an ethylenically unsaturated monomer having a photosensitive group. The copolymer has an excellent photosensitivity and excellent water and oil repellent properties, and is useful for example as a photosensitive material for dry offset printing plate or resist and as a photo-curable, water and oil repelling coating material.
