    摘要： A water-soluble, cationic, thermosetting, polyureideepihalohydrin-formaldehyde resin condensate is formed by reacting a polyalkylene polyamine with urea to form a polyureide intermediate, quenching the polyureide-forming reaction, reacting the polyureide with epihalohydrin and finally reacting the polyureide-epihalohydrin intermediate with formaldehyde to form the water-soluble, cationic, thermosetting resin product. The product is useful as a wet-strength additive in paper and as the resin component in aqueous printing fluids which are, in turn, useful in the high speed printing or decorating of absorbent papers.

    摘要： A WATER-SOLUBLE, CATIONIC, THERMOSETTING, POLYUREIDEFORMALDEHYDE RESIN CONDENSATE IS FORMED BY REACTING A POLYALKYLENE POLYAMINE WITH A UREA TO FORM A POLYUREIDE INTERMEDIATE, THEN QUENCHING THE POLYUREIDE-FORMING REACTION WITH AN ORGANIC HYDROXYL-CONTAINING COMPOUND, AND THEN FINALLY REACTING THE QUENCHED POLYUREIDE INTERMEDIATE WITH FORMALDEHYDE TO FORM THE WATER SOLUBLE, CATIONIC, THEREMOSETTING RESIN PRODUCT. THE PRODUCT IS USEFUL AS A WET-STRENGTH ADDITIVE IN PAPER AND AS THE RESIN COMPONENT IN AQUEOUS PRINTING FLUIDS WHICH ARE, IN TURN, USEFUL IN THE HIGH SPEED PRINTING OR DECORATING OF ABSORBENT PAPERS.
