A water-based ink jet capable of producing a printed matter having low viscosity, good ejection stability, and excellent gloss, abrasion resistance and water resistance even when printing on a plastic substrate. Provided is a polymer composition for water-based ink-jet inks capable of preparing an ink. (1) (a) in the presence of a reactive emulsifier, (b) a monomer having one ethylenically unsaturated bond in the molecule, and (c) a polymer obtained by emulsion polymerization of divinylbenzene; (2) A polymer composition for water-based ink-jet inks containing a polyethylene-based wax, which is used to prepare a water-based ink-jet ink for printing on a plastic substrate by adding to the water-based ink.
