New ß-ketocarbonylquat compounds which contain one or more ß-ketocarbonyl groups of the general formula (I) and one or more quaternary ammonium groups, where the radicals R can be identical or different and are each an aliphatic hydrocarbon radical having from 6 to 28 carbon atoms, are described. The ß-ketocarbonyl group of the formula (I) is preferably bound to a radical Y which is a divalent radical of the formula -O-, -NH-, -NR1-, preferably -NH-, -NR1-, or a trivalent radical of the formula =N-, where R1 is a monovalent hydrocarbon radical having from 1 to 30 carbon atoms. The new ß-ketocarbonylquat compounds are prepared by reacting alkylketene dimmers (1) of the general formula (III) with amino compounds (2) which contain at least one tertiary amino group and at least one protic group selected from the group of the formulae -OH, -NH2, -NHR1 and -NH-, where R and R1 are as defined above, in a first step to give compounds (3) having tertiary amino groups and partially or fully quaternizing the tertiary nitrogen atoms of the compounds (3) obtained in the first step with alkylating agents (4) in a second step.
