AMPHOTERIC LATICES

摘要

Amphoteric latices formed by co-polymerising monomeric polymerisable compounds including a base monomer, a monomer including an amine group and a monomer including a carboxyl group by the use of a polymerisation catalyst, the latices having ionisable amine and carboxyl groups on their surfaces and displaying the characteristic that their surface charge is dependant on pH and can vary from positive to negative.
