Claims13
An imide of the formula I ##STR9## wherein R.sup.1 and R.sup.2 independently of one another are each hydrogen or methyl, n is 1, 2 or 3, and R.sup.3 is a direct bond with n being 1, or C.sub.2 -C.sub.20 -alkylene, ##STR10## when n is 2, ##STR11## when n is 2, ##STR12## when n is 3, --CH.sub.2 --CH.sub.2 [OCH.sub.2 CH.sub.2 ].sub.m when n is 1 or --CH.sub.2 CH.sub.2 CH.sub.2 [OCH.sub.2 CH.sub.2 CH.sub.2 ].sub.m when n is 1 with m=1-10, C.sub.5 -C.sub.20 cycloalkylene or bis(C.sub.5 -C.sub.20 cycloalkylene) C.sub.1 -C.sub.3 alkane having the OH(s) substituted on the cycloalkylene ring, a C.sub.6 -C.sub.10 aromatic radical or said C.sub.6 -C.sub.10 aromatic radical substituted by C.sub.1 -C.sub.4 alkyl, or a group of the formula II ##STR13## wherein T is methylene, isopropylidene, CO, O, S or SO.sub.2 ;
- the OH groups being bound to different C atoms of R.sup.3.
