Claim:
A compound comprising at least two organopolysiloxane units and at least one methylol group of the formula (1) L 1 L 2 N-M1 (1) where M1 is an —HCR 1 —OH radical, R 1 is hydrogen or an optionally NC- or halogen-substituted C 1 -C 10 -hydrocarbyl radical, and L 1 and L 2 are organic N—C-bonded radicals, of which at least L 1 comprises at least one organopolysiloxane unit bonded to N via an Si—C bond, a carbon atom in the N—C bond to L 2 being an aliphatically saturated carbon atom, and wherein at least 50% of organopolysiloxane units bear unsubstituted hydrocarbyl radicals or Si—O—Si bonds, having the formula (2) Q-(2a,2b) c -Q (2) where the units 2a and 2b may be disposed randomly, blocklike, alternatingly or in a mixture thereof, the units 2a and 2b conforming to the formulae (2a) and (2b) where 1 and c represent a whole number of at least 1, R 5 is M1 or hydrogen, with the proviso that at least one R 5 radical is not hydrogen, R is hydrogen or a monovalent C 1 -C 20 -hydrocarbyl or C 1 -C 20 -hydrocarbyloxy radical, each of which is optionally substituted with —CN, —NCO, —NR 2 2 , —COOH, —COOR 2 , —PO(OR 2 ) 2 , -halogen, -acryloyl, -epoxy, —SH, —OH or —CONR 2 2 , and in each of which one or more nonadjacent methylene units are optionally replaced by a group —O—, —CO—, —COO—, —OCO—, —OCOO—, —S—, —NR 2 —, —(CH 2 CH 2 O) n — or —(CH 2 CHCH 3 O) n —, and in each of which one or more nonadjacent methine units are optionally replaced by a group —N═, —N═N—or —P═, R 2 is hydrogen or a monovalent optionally NC—, —OCN— or halogen-substituted C 1 -C 10 -hydrocarbyl radical, n is a whole number from 1 to 1000, X is an alkylene radical which has 1 to 60 carbon atoms and in which nonadjacent methylene units are optionally replaced by a group —O— or —S—, A is an oxygen atom, a sulfur atom or —NR 5 —, Z is an oxygen atom, a sulfur atom or —NR 5 —, Y is a bivalent, optionally fluorine- or chlorine-substituted hydrocarbyl radical which has 1 to 20 carbon atoms bonded to N of the NR 5 groups in the formulae 2a, 2b by an N—C bond at an aliphatically saturated carbon atom, D is an alkylene radical which has 1 to 700 carbon atoms, which is optionally substituted by fluorine, chlorine, C 1 -C 6 -alkyl or C 1 -C 6 -alkyl ester and in which mutually nonadjacent methylene units are optionally replaced by groups —O—, —COO—, —OCO— or —OCOO— and which optionally contains neutralized or free amine, carboxylic acid or sulfonic acid groups, and Q is a reactive or nonreactive end group attached to the polymer by a covalent bond.
