Abstract
Disclosed are novel retention aid resins for paper fillers, said resins being derived by reaction of a nitrogen compound (such as ammonia) and a base resin which is the reaction product of an amino polymer and an epoxide difunctional toward amines. A specific example of such a base resin is a cationic water-soluble polyaminopoly-ureylene -- epihalohydrin resin.
