Abstract

Aqueous polymer dispersion comprising from 0.1 to 10 parts by weight per 100 parts by weight of polymer of an emulsifier A) having a phosphate group, wherein said emulsifier consists at least 50% by weight of ethylene oxide and propylene oxide groups and the proportion of the ethylene oxide groups and propylene oxide groups is in each case at least 10% by weight, based on the overall amount of the ethylene oxide and propylene oxide groups.
