ABSTRACT:
The present invention relates to compounds of the formula (I) ##STR1## where R.sup.1 is H or an alkyl radical having from 1 to 12 carbon atoms, R.sup.2 is a straight-chain alkylene radical having from 1 to 8 carbon atoms, an oxygen-containing alkylene radical having from 2 to 4 carbon atoms, a radical of the formula (II) or (III) ##STR2## or a cycloalkylene radical having from 3 to 10 carbon atoms, R.sup.3 is an alkyl radical having from 1 to 25 carbon atoms or an aryl radical having from 6 to 10 carbon atoms, A is a radical --COO.sup.- or --SO.sub.3 .sup.- and x=0, y=1, m=1 and n=1, or x=1, y=1, m=(1 or 2) and n=(1 or 2), or, if R.sup.2 is a radical of the formula (II) or (III), x=1, y=0, m=(0 or 1) and n=(0 or 1), and also a process for their preparation.
