Abstract: Aqueous preparation (I) comprises 10-80 wt.% of carboxyfunctional organopolysiloxane-polyammonium-copolymers (A), which is produced by reacting an organopolysiloxane compound with at least a compound of e.g. maleic acid, fumaric acid, citraconic acid, mesaconic acid, itaconic acid to give olefinic unsaturated organopolysiloxane macro monomers (B) and subsequent radical polymerization of (B) with co-monomers of e.g. diallyldimethylammoniumchloride, 0-20 wt.% of an emulsifying agent, 0-25 wt.% of a hydrotropic and 20-90 wt.% of water. Aqueous preparation (I) comprises 10-80 wt.% of carboxyfunctional organopolysiloxane-polyammonium-copolymers (A), which is produced by reacting an organopolysiloxane compound of formula R1>-Si(CH3)2-O-(Si(CH3)(R3>)-O)a-(Si(CH3)(R4>)-O)b-Si(CH3)2-R2> with at least one compound of maleic acid, fumaric acid, citraconic acid, mesaconic acid, itaconic acid, 2-methyleneglutaric acid, trans, trans-2,4-hexadienicdiacid, maleic acid anhydride, citraconic acid anhydride, itaconic anhydride, methyl-5-norbornen-2,3-dicarbonic acid anhydride, 4,10-dioxatricyclo[5.2.1.0-2,6-]dec-8-en-3,5-dione, cis-5-norbornen-endo-2,3-dicarboxylic acid anhydride, cis-5-norbornen-exo-2,3-dicarboxylic acid anhydride, bicylco[2.2.2]-oct-5-en-2,3-dicarboxylic acid anhydride, 3-(2-neopentylallyl tetrahydrofuran-2,5-dione), nonenylbernsteinic acid anhydride, 3-(2-methyl-2-propenyl)dihydro-2,5-furandione, 5-methyl-3a, 4,7,7a-tetrahydro-2-benzofuran-1,3-dione, 3-(3-methyl-2-butenyl)dihydro-2,5-furandione, 5,6-dimethyl 3a,4,7,7a-tetrahydro-2-benzofuran-1,3-dione, 2-octen-1-ylbernsteinic acid anhydride and 3-[(2E)-2-decenyl]dihydro-2,5-furandione to give olefinic unsaturated organopolysiloxane macro monomers (B) and subsequent radical copolymerizing (B) with co-monomers of diallyldimethylammoniumchloride, diallylmethylamine, diallylamine, [(2-methacryloyloxy)-ethyl]-tri methyl ammonium chloride, [(2-methacryloyloxi)-ethyl]-trimethylammoniummethosulfate, [(2-acryloyloxy)-ethyl]-tri methyl ammonium chloride, [(2-acryloyloxi)-ethyl]-trimethylammoniummethosulfate, (3-acrylamidopropyl)tri methyl ammonium chloride, dimethylaminoethylmethacrylate, dimethylaminopropylmethacrylamide, N-methyl-2-vinylpyridiniumchloride and N-methyl-4-vinylpyridiniumchloride to give (A), where the total nitrogen content of (A) is 3-9 wt.% and the nitrogen content of organopolysiloxane is 0.2-4.5 wt.%, 0-20 wt.% of an emulsifying agent, 0-25 wt.% of a hydrotropic and 20-90 wt.% of water. R1>, R2>, R4>diazetidine compound of formula (I), (-R7>)(R6>)-N-(R8>) or -(CH2)d-NH-(CH2)e-NH2 (under the condition that at least one of the remainders of R1>, R2>, R4> is primary or secondary amino group and R1>, R2>, R4> is optionally, trimethylsiloxygroup); R3>-(CH2)f-H or -benzene; R5>-(CH2)3-O-CH2-CH(OH)-CH2-, -(CH2)3-O-CH2-CH(CH2-OH)-, cyclohexanol compound of formula (A or B); R6>, R8>H or 1-4C alkyl; R7>one of the components of R5> or (-(CH2)3- or -CH2-CH(CH3)-CH2-); a : 5-200; b : 0-5; c : 2 or 3; d : 1-10; e : 1-10; and f : 1-10.
