摘要： The present invention provides: an aqueous fast-drying resin composition which is excellent in the fast driability and can exhibit performances with regard to adhesion and resistance on a level with those of solvent type compositions; a production process for the aqueous fast-drying resin composition; and a use of the aqueous fast-drying resin composition as a gravure ink composition. An aqueous fast-drying resin composition comprises an anionic resin, a cationic resin, and a polyvalent metallic compound. In addition, another aqueous fast-drying resin composition comprises an aqueous medium and a resin component wherein the aqueous medium will be removed by drying. In this aqueous fast-drying resin composition, the resin component is combined with a polyvalent metallic compound and includes a combination of an anionic resin and a cationic resin. The production process for the aqueous fast-drying resin composition comprises the step of combining the anionic resin, the cationic resin, and the polyvalent metallic compound. The gravure ink composition comprises the above aqueous fast-drying resin composition and a pigment and/or dye.
