Aqueous fast-drying resin composition and its production process and use

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. An aqueous fast-drying resin composition comprises a combination of a water-soluble anionic resin having a weight-average molecular weight of not lower than 1,000, a cationic resin having a number-average molecular weight of 600 to 5,000,000, 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 includes a combination of a water-soluble anionic resin having a weight-average molecular weight of not lower than 1,000 and a cationic resin having a number-average molecular weight of 600 to 5,000,000, and is combined with a polyvalent metallic compound.
