Claim:
A β-ketocarbonylquat having the formula [R 3 R 4 R 5 N (+) —R 2 —] a Y—ZX (−) (II) wherein a is 1 or 2, with the proviso that when a is 1, Y is a divalent radical and when a is 2, Y is a trivalent radical, Y is a divalent radical of formula —O—, —NH—, —NR 1 —, or a trivalent radical of formula ═N—, X (−) is a counter-ion to the positive charge on the quaternary nitrogen atom, Z is a β-ketocarbonyl group of the formula R—CH 2 —(C═O)—CHR—(C═O)— (I) R each, independently is an aliphatic hydrocarbon radical of 6 to 28 carbon atoms, R 1 is a monovalent hydrocarbon radical of 1 to 30 carbon atoms, R 2 is a divalent C 1 -C 18 hydrocarbon radical which optionally contain one or more separate oxygen atoms, R 3 each, independently, is a monovalent hydrocarbon radical of 1 to 30 carbon atoms, R 4 is R 3 or a radical of the formula —R 1 —Y—Z or —R 1 —N (+) R 3 2 R 5 X (−) , or R 3 and R 4 together or two R 3 radicals together are a divalent C 3 -C 12 hydrocarbon radical which optionally contains an oxygen atom or a nitrogen atom, and R 5 is a monovalent hydrocarbon radical of 1 to 18 carbon atoms.
