Abstract
A resin composition for an aqueous ink includes a base resin, an aqueous dispersion medium, and an emulsifier. The base resin includes a rosin-modified alkyd resin. The emulsifier includes an anionic emulsifier and a nonionic emulsifier. The anionic emulsifier includes an oxyalkylene-containing anionic emulsifier. An HLB value of the nonionic emulsifier is 16.0 or more and 20.0 or less.
