<p>There are prepared compounds of the formulae <IMAGE> I and <IMAGE> II where R and R1 are saturated alkyl groups in which the sum of the carbon atoms in the two alkyl groups is 4 to 30 carbon atoms and wherein one of R and R1 can be hydrogen, R2 is hydrogen, lower alkyl with one to five carbon atoms, 2-hydroxyethyl, 2-hydroxypropyl, 2,3-dihydroxypropyl, benzyl,o-,m- or p-methylbenzyl, o-,m- or p-chlorobenzyl, o-,m- or p-bromobenzyl, aminoalkyl (C2 to C6), preferably aminoalkyl (C2 and C3), alkyl (C1 to C5)-aminoalkyl (C2 to C6), 2-hydroxyethyl-aminoalkyl (C2 to C6), 2-hydroxypropyl-aminoalkyl (C2 to C6) or 2,3-dihydroxy-propyl-aminoalkyl (C2 to C6), R3 in case the compound is present as the ammonium salt is hydrogen or a lower alkyl group with 1 to 5 carbon atoms, and X- is a monovalent, inorganic or organic acid group or one equivalent of a polybasic inorganic or organic group.</p> |
