| abstract |
The (meth) acrylic copolymer of the present invention is a structural unit (A1) or a triorganosilyloxycarbonyl group having at least one kind of structure (I) represented by formula (1), formula (2) or formula (3). At least one structural unit (A) selected from the group consisting of a structural unit (A2) having a structural unit (A3) having at least one of a structural unit (A2) represented by formula (4) or formula (5) ), A structural unit (B) derived from a specific polysiloxane block-containing polymerizable monomer (b), and a structural unit (C) derived from a macromonomer (c). |
