PROBLEM TO BE SOLVED: To provide a block polymer capable of enhancing the block property of other monomer so that physical properties due to a hydroxyl group-containing polymerizable monomer are not changed by the sequence of a polymer in an acrylic polymer comprising three or more components.SOLUTION: There is provided a block polymer which is an acrylic polymer obtained by polymerizing a polymerizable monomer comprising three or more components and comprises a first polymer unit comprising a first polymerizable monomer having a hydroxyl group and a second polymerizable monomer and a second polymer unit comprising a first polymerizable monomer having a hydroxyl group and a third polymerizable monomer which is different from the second polymerizable monomer. |
