Abstract
An aqueous polymer dispersion comprising polymer particles (A), polymer particles (B) and at least one low molecular weight polymer (C) where polymer particles (A) comprise high molecular weight polymer pA having Mw >50,000 and acid number of from 0 to 160, polymer particles (B) comprise high molecular weight polymer pB having Mw >50,000 and acid number of from 0 to 160, and C is an addition polymer having a calculated Tg,(low) of less than 10° C., Mn <10,000, acid number of from 0 to 80, formed by the polymerization of at least one ethylenically unsaturated nonionic monomer.
