Claim:
Polysiloxane compound containing: a) At least one polyalkylene oxide structural unit with the formula: —A—E—, —E—A—, —A—E—A′, and/or —A′—E—A— wherein A=—CH 2 C(O)O—, —CH 2 CH 2 C(O)O—, —CH 2 CH 2 CH 2 C(O)O—, —OC(O)CH 2 —, —OC(O)CH 2 CH 2 — and/or —OC(O)CH 2 CH 2 CH 2 — A′=—CH 2 C(O)—, —CH 2 CH 2 C(O)—, CH 2 CH 2 CH 2 C(O)—, —C(O)CH 2 —, —C(O)CH 2 CH 2 — and/or —C(O)CH 2 CH 2 CH 2 — E=a polyalkylene oxide group of the formulae: —[CH 2 CH 2 O] q —[CH 2 CH(CH 3 )O] r —and/or —[OCH(CH 3 )CH 2 ] r —[OCH 2 CH 2 ] q — With q=1 to 200, r=0 to 200, whereby the terminal position oxygen atom of Group A binds to the terminal position —CH 2 -group of Group E, and the terminal position carbonyl carbon atom of Group A′ binds to the terminal position oxygen atom of Group E forming ester groups in each case, and/or at least one terminal position polyalkylene oxide structural unit of the formula —A—E—R 2 wherein A and E have the aforementioned meaning, and R 2 =is H, straight chain, cyclical or branched C 1 –C 20 -hydrocarbon radical, which can be interrupted by —O—, or —C(O)— and substituted with —OH, and can be acetylenic, olefinic or aromatic b) at least one bivalent or trivalent organic radical which contains at least one ammonium group, the free valences of which are saturated by structural units selected from the group consisting of structural unit a) and structural unit c), c) at least one polysiloxane structural unit with the formula: —K—S—K—, with wherein R 1 =C 1 –C 22 -alkyl, C 1 –C 22 -fluoralkyl or aryl, n=0 to 1000, end these can be identical or different if several S Groups are present in the polysiloxane compound, K=a bivalent or trivalent straight chain, cyclical or branched C 2 –C 40 hydrocarbon residue which is optionally interrupted by —O—, —NH—, —NR 1 —, —C(O)—, —C(S)—, or and optionally substituted with —OH, wherein R 1 is defined as above, or represents a bond to a bivalent radical R 3 R 3 represents a monovalent or bivalent straight chain, cyclical or branched C 1 –C 20 hydrocarbon radical which is optionally interrupted by —O—, —NH—, —C(O)—, —C(S)— and can be substituted with —OH, or —A—E—R 2 , wherein A, E and R 2 are defined as above, whereby the residues K can be identical or different from each other, and in the event that K represents a trivalent organic radical which contains at least one ammonium group, the saturation of the third valence takes place through a bonding to the above mentioned organic radical which contains at least one ammonium group, d) at least one organic or inorganic acid residue for neutralization of the charges resulting from the ammonium group(s).
