Abstract
Anthraquinones of formula I ##STR1## wherein X is the group --CR.sup.2 R.sup.3 --, where R.sup.2 is H, --CH or C.sub.1 -C.sub.5 -alkyl and R.sup.3 is H or --CN, R.sup.1 is H or C.sub.1 -C.sub.5 -alkyl and R is a direct bond or linear or branched C.sub.1 -C.sub.18 -alkylene which, alone or together with the --CR.sup.2 R.sup.3 -- group, can be interrupted by one or more --O-- when R.sup.2 and/or R.sup.3 are not --CN, and curable compositions comprising (a) an epoxy resin, (b) a hardener if necessary, (c) an anthraquinone of formula I and (d) an amino alcohol. The cured compositions are photosensitive and are suitable for the preparation of coatings and metallic images by electroless metal deposition.
