Abstract

A novel aqueous emulsion solution is provided that can be used as a binder for forming a coating film suitable for an inkjet printing system. The present invention is an aqueous emulsion solution containing a polymer I and a polymer II mixed together therein, wherein the polymer I is an A-B block copolymer formed from 90 mass % or more of a methacrylate-based monomer, the A-B block copolymer neutralized with an alkali, a polymer block A is substantially water-insoluble and has a number average molecular weight of 1000 to 10000 and a polydispersity index of 1.5 or less, a polymer block B is synthesized using a monomer containing at least a methacrylic acid and has an acid value of 30 to 250 mgKOH/g, the A-B block copolymer has a number average molecular weight of 5000 to 20000, a content of the polymer block A of 5 to 60% in the A-B block copolymer, and a polydispersity index as a whole of 1.6 or less, the polymer II is a polymer obtained by polymerizing a hydrophobic addition polymerizable monomer and having a glass transition temperature of 70° C. or lower, and further the mass ratio of the polymer I and the polymer II is 5 to 80:95 to 20.
