PROBLEM TO BE SOLVED: To provide a dyeability improver for polyolefin resin which imparts excellent dyeability for cationic dye to polyolefin resin without impairing mechanical strength.SOLUTION: This invention provides a dyeability improver for polyolefin resin which comprises a copolymer comprising polyolefin, unsaturated (poly) carboxylic acid (anhydride), and organic sulfonic acid (salt) having one polymerizable unsaturated group as constitutional units, wherein the dyeability improver for polyolefin resin may further have aliphatic unsaturated hydrocarbon added as a constitutional unit. |
