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.
本发明提供了一种水性快干树脂组合物,它具有优异的快干性,并且在粘附性和抗腐蚀性方面的性能可与溶剂型组合物媲美。一种水性快干树脂组合物由重量平均分子量不低于 1 000 的水溶性阴离子树脂、数均分子量在 600 至 5 000 000 之间的阳离子树脂和多价金属化合物组合而成。此外,另一种水性快干树脂组合物包括水性介质和树脂成分,其中水性介质将通过干燥去除。在这种水性快干树脂组合物中,树脂组分包括重量平均分子量不低于 1,000 的水溶性阴离子树脂和数均分子量在 600 至 5,000,000 之间的阳离子树脂的组合,并与多价金属化合物结合。
