Abstract
Provided is an aqueous ink for ink jet, containing a resin particle, and a cyclic amide-based, water-soluble organic solvent. The resin particle has a core portion that contains a cyano group-containing unit, and a shell portion that contains an aromatic group-containing unit, an anionic group-containing unit and a unit derived from a crosslinking agent, but free of cyano group-containing unit. Ink jet recording using the aqueous ink can record images that excel in abrasion resistance and gloss clarity.
