SIZING AGENT FOR PAPERMAKING BASED ON KETENE DIMER AND METHOD FOR SIZING

摘要

PROBLEM TO BE SOLVED: To provide a ketene dimer-based sizing agent excellent in sizing properties, especially hard to form aggregate in combinedly using a polyacrylamide- based paper reinforcing agent.;SOLUTION: This invention provides the ketene dimer-based sizing agent which comprises a dispersing phase including the ketene dimer and an aqueous continuous phase including a dispersing agent or the like, includes an acid and a salt in the aqueous continuous phase, the method for sizing paper uses the ketene dimer-based sizing agent.;COPYRIGHT: (C)2003,JPO
