摘要
The present invention provides a water-soluble thermosetting resin giving high wet-strength of paper and excellent preservation stability which comprises 20% by weight or less of components having a molecular weight of 10,000 or less; and a water-soluble thermosetting resin giving high wet-strength of paper in which, in a reverse mutation test carried out for the resin as the object to be tested using histidine-requiring Salmonella typhimurium TA1535 strain, the number of reversant colonies generated is less than twice the number of reversant colonies in the solvent control, treated only the solvent as a reference liquid are provided; and a process for producing an aqueous cationic thermosetting resin solution giving excellent preservation stability of the solution is also provided.
