Abstract

Aqueous polymer dispersions contain, as a dispersant, a mixture of an ethylene oxide/propylene oxide copolymer, an ethoxylated alkylphenol and/or an ethoxylated fatty alcohol, an ethoxylated polysaccharide and, if required, as a further component, sulfuric acid half-esterified with an ethoxylated alkylphenol and/or an ethoxylated fatty alcohol.
