摘要： The present invention provides an ink composition for inkjet recording with which high-speed printing is possible while maintaining the quality of a printed material. An ink composition for inkjet recording, including: a color material, a binder resin, and an organic solvent, wherein the binder resin contains at least an acrylic-based resin (A), and a copolymer (B) having a constitutional unit derived from a hydroxyalkyl (meth)acrylate, a constitutional unit represented by the following general formula (I), and a constitutional unit represented by the following general formula (II), a content ratio by mass of the acrylic-based resin (A) to the copolymer (B) ((A)/(B)) is 25/75 or more and 70/30 or less, and wherein the organic solvent contains at least a polyalkylene glycol dialkyl ether and a cyclic ester, a content ratio of the cyclic ester is 3 parts by mass or more and 10 parts by mass or less relative to 100 parts by mass of the ink composition, and a content ratio of the polyalkylene glycol dialkyl ether is 5 parts by mass or less relative to 100 parts by mass of the ink composition: wherein each symbol in the general formula (I) and the general formula (II) is as described in the description).
