Zusammenfassung:	Suggested are hydrophobically modified alkali swellable emulsions, comprising polymers consisting of the following monomers: (a) 20 to 55 % b.w. acrylic and/or methacrylic acid, (b) 40 to 80 % b.w. C 1 -C 4 alkyl (meth)acrylates, (c) 1 to 40 % b.w. of a maleic acid ester according to general formula (I) R 2 OOC-CH=CH-COO(CH 2 CH 2 O) n R 1 (I) in which R 1 stands for a linear or branched alkyl, aryl or alkaryl radical having 8 to 22 carbon atoms, R 2 stands for hydrogen or (CH 2 CH 2 O) n R 1 and n means a number between 2 and 150, (d) 0 to 15 % b.w. of aralphatic compounds having at least one double bond in the aliphatic side chain, and (e) 0 to 1 % b.w. polyethylenic unsaturated cross-linking monomer, calculated on the total composition of the polymers and under the condition that compounds (a) to (e) add up to 100 % b.w.
