A novel maleimide which has excellent compatibility with a polyfunctional (meth) acrylate and good alkali solubility, and thus can be suitably used in various applications requiring such characteristics. A system copolymer is provided. The maleimide copolymer according to the present invention is a maleimide copolymer having excellent compatibility with a polyfunctional (meth) acrylate and having a weight average molecular weight of 5,000 to 50,000, and is derived from an unsubstituted maleimide. 2 to 40% by weight of a monomer structural unit, 5 to 50% by weight of a monomer structural unit derived from styrene, and 6 to 50% by weight of a monomer structural unit derived from (meth) acrylic acid. It is characterized. [Selection diagram] None |
