• in which R2 is a monovalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 100 carbon atoms, which may contain one or more groups selected from —O—, —NH—, —C(O)— and —C(S)—, and which may if desired be substituted by one or more substituents selected from the group consisting of a hydroxyl group, an unsubstituted or substituted heterocyclic group preferably containing one or more nitrogen atoms, amino, alkylamino, dialkylamino, ammonium, polyether radicals and polyetherester radicals, and, if there are two or more groups —CONR2—, they may be identical or different,
• R3 has the definition of R2, it being possible for R2 and R3 to be identical or different, or
• R2 and R3 together with the positively charged nitrogen atom form a five- to seven-membered heterocycle, which if desired may additionally contain one or more nitrogen, oxygen and/or sulfur atoms,
• R5, R6 and R7 can be identical or different and are selected from the group consisting of hydrogen, halogen, hydroxyl group, nitro group, cyano group, thiol group, carboxyl group, alkyl group, monohydroxyalkyl group, polyhydroxyalkyl group, thioalkyl group, cyanoalkyl group, alkoxy group, acyl group, acetyloxy group, cycloalkyl group, aryl group, alkylaryl group, and groups of the type —NHRW, in which RW is hydrogen, alkyl group, monohydroxyalkyl group, polyhydroxyalkyl group, acetyl group or ureido group, and pairs of adjacent radicals R5, R6 and R7 may, with the carbon atoms bonding them to the heterocycle, form aromatic five- to seven-membered rings, and
• R8 has the definition of R2, it being possible for R8 and R2 to be identical or different,
• Q not bonding to a carbonyl carbon atom,
• V represents at least one group V1 and at least one group V2
• in which
• V2 is selected from divalent or trivalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals having up to 1000 carbon atoms (not including the carbon atoms of the polysiloxane radical Z2, defined below) and containing, if desired, one or more groups selected from
• —O—, —CONH—,

• V1 is selected from dihydric or trihydric, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals having up to 1000 carbon atoms, which if desired may contain one or more groups selected from
• —O—, —CONH—,
• —CONR2—, in which R2 is as defined above, it being possible for the groups R2 in the groups V1 and V2 to be identical or different,
• —C(O)—, —C(S)— and -Z1-, in which -Z1- is a group of the formula
• in which
• R1 is as defined above, it being possible for the groups R1 in the groups V1 and V2 to be identical or different, and

• that the radical V1 may not contain any ester group(s) —C(O)—O— and/or —O—C(O)—.
• that the trivalent radicals Q and the trivalent radicals V1 or V2 serve exclusively for saturating one another within the linear main change of the stated polysiloxane copolymers, and
• that in the stated polysiloxane copolymer the molar ratio
• V2/V1≠1,
• and in which the positive charges resulting from the ammonium groups are neutralized by organic or inorganic acid anions,
• and the acid addition salts thereof.
