[Problem] To provide a lipophilic, highly branched polymer, and a photopolymerizable composition containing the same, that can mix and disperse well in a matrix resin and can impart surface modifying properties such as excellent lipophilicity (fingerprint resistance) to a cured film obtained from a resin composition, without impairing the natural transparency of resin. [Solution] A lipophilic, highly branched polymer, and a photopolymerizable composition containing the same, obtained by polymerizing monomer A, which contains at least two radical polymerizable double bonds, and monomer B, which contains a C 6 n ‑ n 30 alkyl group or C 3 n ‑ n 30 alicyclic group and at least one radical polymerizable double bond, in the presence of a polymerization initiator C in an amount of 5 to 200 mol% in relation to monomer A. |
