Abstract (en)
[origin: US2003229172A1] Aqueous dispersions comprising microfine metal oxide particles and dispersion auxiliaries, wherein, as dispersion auxiliaries, at least one of the compounds of the general formula (I) in which M is hydrogen, monovalent or divalent metal cation, ammonium ion, organic amine radical; a is 1, or where M is a divalent metal cation, is ½; X is likewise -OMa or -O-(CpH2pO)q-R<l >where R<1>=H, aliphatic hydrocarbon radical having 1-20 carbon atoms, cycloaliphatic hydrocarbon radical having 5 to 8 carbon atoms, optionally substituted aryl radical having 6 to 14 carbon atoms, p=2 to 4, q=0 to 100, -NHR<2 >and/or -NR<2>2 where R<2>=R<1 >or -CO-NH2; Y is O, NR<2>; A<1 >is ethylene radical, propylene radical, isopropylene radical, butylene radical; m is 10 to 30; n is 0 to 50; and k is 10 to 30, where the summ+k is in the range from 20 to 60, is co-used.
