Abstract
There is provided a highly branched lipophilic polymer that is excellent in blending and dispersing properties in a matrix resin, and is possible to provide surface modification properties such as excellent lipophilicity (anti-fingerprint property) and the like to a coating that is obtained from the resin composition while the intrinsic transparency of the resin is not impaired; and a photopolymeizable composition comprising the highly branched lipophilic polymer. A highly branched lipophilic polymer obtained by polymerizing a monomer A containing two or more radically polymerizable double bonds per molecule and a monomer B containing a C6-30 alkyl group or a C3-30 alicyclic group and at least one radically polymerizable double bond per molecule in the presence of 5 to 200 mol % of a polymerization initiator C relative to the number of moles of the monomer A. A photopolymeizable composition comprising the highly branched lipophilic polymer.
