Abstract

Abstract Compounds containing at least 5 mol % of structural units of the formulae I and/or II ##STR1## in which Q is an unsubstituted or substituted tetravalent aromatic radical to which in each case two carbonyl groups are bonded in the ortho- or peri-position, R 1 is selected from the radicals of the formulae III, IV and V ##STR2## R 2 , R 3 , R 4 and R 5 are hydrogen, alkyl, cycloalkyl or substituted or unsubstituted aryl or aralkyl, R 6 and R 7 are aryl or halogen, m and n are 0, 1 or 2 and o is 0, 1, 2, 3 or 4, are described. The compounds are distinguished by an increased resistance to oxidation by heat. They can be used to produce coatings and relief structures.
