PROBLEM TO BE SOLVED: To provide a photocurable composition suitable for a photocurable adhesive layer of an optical film and excellent in yellow discoloration resistance, adhesiveness and resin elution resistance (liquid crystal contamination resistance).SOLUTION: A polymer represented by formula (I), and a photocurable composition comprising the polymer are provided. In the formula, Q represents a photosensitive group; k, l, m and n satisfy 100<k+l+m+n<5000; and Q represents a functional group having a photo-dimerizable unsaturated bond and is preferably a cinnamyl group, cinnamoyl group, cinnamylidene group, cinnamylidene acetyl group, chalcone group, coumarin group, isocoumarin group, 2,5-dimethoxy stilbene group, maleimide group, α-phenylmaleimide group, 2-pyrone group, azide group, thymine group, quinone group, uracil group, pyrimidine group, stilbazolium group, styryl pyridinium group, or styryl quinolium group.SELECTED DRAWING: None |
