    • It is an object of the present invention to provide an alkali-soluble maleimide-based copolymer excellent in resistance for thermally yellowing, high in hardness, excellent in solubility in solvents and capable of readily forming uniform coat films and, in addition, capable of being satisfactorily dissolved in alkali water when remaining uncured, as well as a pigment dispersion composition comprising such copolymer and an ionizing radiation-curable resin composition comprising such copolymer. Another object of the present invention is to provide a color filter and a liquid crystal display which are formed by using the ionizing radiation-curable resin composition. The present invention is related to an alkali-soluble maleimide-based copolymer which comprises, as essential constituents, 5 to 50% by mass of a maleimide monomer unit which is at least one unit selected from the group consisting of a N-cyclohexylmaleimide monomer unit, a N-benzylmaleimide monomer unit and a substituted N-benzylmaleimide monomer unit, 8 to 30% by mass of the (meth)acrylic acid monomer unit and 30 to 87% by mass of a (meth)acrylic acid ester monomer unit and which satisfies the condition represented by the formula: 0.4 X Y 0.5 X + 10 where X is the content, in % by mass, of the N-cyclohexylmaleimide monomer unit, the N-benzylmaleimide monomer unit and the substituted N-benzylmaleimide monomer unit and Y is the content, in % by mass, of the (meth)acrylic acid monomer unit.
