Claim 1

A compound of the formula I ##EQU1## wherein R' denotes a hydrogen atom and/or the methyl group, Y denotes ##EQU2## a denotes, as an average value, a number between 1.0 and 12, n denotes, as an average value, a number from 0.5 to 8, R denotes a linear or branched alkyl radical having 8 to 24 carbon atoms, which can be interrupted once by the groups, --O-- or --S--, or denotes phenyl, phenyl substituted by linear or branched alkyl groups, or phenylalkylene having 1 to 3 carbon atoms in the alkylene chain, the alkylene chain or the linkage thereof to the phenyl group optionally interrupted by an oxygen or sulphur atom, and for the phenyl radical thereof optionally substituted by linear or branched alkyl groups, and in all cases the phenylalkylene radical contains 7 to 30 carbon atoms, and in the case where R' is the methyl group, R also denotes a linear or branched alkyl group having 1 to 7 carbon atoms, the sum of the carbon atoms of R and of the radical ##EQU3## in formula I being 8 to 40.
