Abstract
Compounds of the general formula I ##STR1## in which R.sub.1 is chlorine or --CH.sub.2 --CCl.sub.3, and PA0 R.sub.2 is --N(R.sub.3)R.sub.4, --OH.N(R.sub.3)(R.sub.4)R.sub.5 or --OR.sub.6, PA0 R.sub.3 is C.sub.1 -C.sub.24 alkyl which can be interrupted once or several times by oxygen, PA0 R.sub.4 and R.sub.5 independently of one another are hydrogen or C.sub.1 -C.sub.24 alkyl, with R.sub.3 and R.sub.4 together having at least 8 C atoms, PA0 R.sub.6 is C.sub.8 -C.sub.20 alkyl, phenyl or C.sub.7 -C.sub.15 alkylphenyl, a group of the formula --(A)R.sub.7 or --CH.sub.2 CH.sub.2 --N(R.sub.10)--CH.sub.2 CH.sub.2 --O--C(O)--CH(R.sub.1)CH.sub.2 CCl.sub.3, wherein PA0 R.sub.7 is a radical of the formula --(R.sub.8)C(R.sub.9)--O--C(O)--CH(R.sub.1)--CH.sub.2 --CCl.sub.3, wherein PA0 R.sub.8 and R.sub.9 independently of one another are hydrogen, methyl or ethyl, and R.sub.1 has the meaning defined above, PA0 A is a C.sub.1 -C.sub.7 alkylene group which is unsubstituted or substituted by one or two radicals R.sub.7 or by one or two methyl or ethyl groups, and which can be interrupted by --O--, and PA0 R.sub.10 is C.sub.4 -C.sub.20 alkyl.
