Amphoteric promoter resin that is a polymerization reaction product of a quaternary diallylammonium monomer, a diallylammonium monomer, and a unsaturated organic acid as well as compositions containing the amphoteric promoter resin and a sizing agent. The method of sizing paper with such amphoteric promoter resin compound and a sizing agent provides sized paper with significantly improved sizing property characteristics, and the sized paper exhibits superior retention of brightness due to added optical brighteners. |
