Abstract

See full text

The present invention provides an A-B block copolymer that enables preparation of a polymer emulsion useful as a binder component for an aqueous inkjet ink that is excellent in inkjet printability and is capable of forming a printed film excellent in durability, such as adhesiveness and rub resistance, on a substrate to be printed, such as a polyolefin-based plastic film. The block copolymer is an A-B block copolymer satisfying the following requirements (1-1) to (1-3). (1-1) Containing 90% by mass or more of a constituent unit derived from a methacrylate-based monomer or the like. (1-2) The chain A has a constituent unit (A-i) derived from methyl methacrylate or the like and a constituent unit (A-ii) derived from 2-ethylhexyl methacrylate or the like. (1-3) The chain B has a constituent unit (B) derived from methacrylic acid, a constituent unit (B-i) derived from methyl methacrylate or the like, and a constituent unit (B-ii) derived from 2-ethylhexyl methacrylate or the like.
