<p>PROBLEM TO BE SOLVED: To provide a fluorine-containing polymer capable of imparting an excellent antifouling property (oil-based ink repellency, fingerprint stain removal property) to hard coat layer or the like, a hard coat layer forming composition comprising said polymer, and an article having hard coat layer of antifouling property formed from said composition.SOLUTION: A fluorine-containing polymer having monomer unit (U1) having one or more of poly(oxyperfluoroalkylene)chain ((αβ)) formed by linking 2 or more of unit (αβ) which is formed by linking unit (α) consisting of 1 to 3 of at least one of oxyperfluoroalkylene units of 1 to 2 carbons, and unit (β) consisting of 1 to 3 of at least one of oxyperfluoroalkylene units of 3 to 6 carbons, and monomer unit (U2) having one or more of ethylenically unsaturated group; a hard-coat layer forming composition comprising said polymer; and an article having hard coat layer.</p> |
