Abstract
Process for mass-coloring high-molecular organic material, which comprises using a metal complex of the formulae I and/or Ia ##STR1## in which R is a hydrogen or chlorine atom or a methyl or methoxy group, R.sub.1 is a hydrogen atom, C.sub.1 -C.sub.4 -alkyl or phenyl which is unsubstituted or substituted by halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, --NO.sub.2, --CONH.sub.2 --CONHR.sub.2 or C.sub.2 -C.sub.5 -N-alkylcarbamoyl, X is --CH.dbd. or --N.dbd., M is a divalent transition metal, and A is phenyl or substituted phenyl and R.sub.2 is alkyl, phenyl or substituted phenyl. The resulting colorations are distinguished by high tinctorial strength and good fastness properties, such as light, weathering and migration fastness properties.
