Abstract
Process for mass-coloring high molecular weight organic material, which comprises using a compound of the formula I ##STR1## in which one of R.sub.1 and R.sub.2 and one of R.sub.3 and R.sub.4 are, independently of each other, hydrogen, C.sub.1 -C.sub.12 -alkyl or benzyl and the other two radicals are, independently of each other, unsubstituted or halogen-, trifluoromethyl-, cyano-, C.sub.1 -C.sub.12 -alkyl-, --OR.sub.5 -, --SR.sub.5 -, --COR.sub.6 - or --SO.sub.2 R.sub.6 -substituted phenyl, biphenyl or naphthyl or a 5- or 6-membered aromatic heterocyclic ring containing one or more identical or different hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur without or with one or two fused-on benzene rings, R.sub.5 is hydrogen or C.sub.1 -C.sub.12 -alkyl, R.sub.6 is C.sub.1 -C.sub.12 -alkyl, and X and Y are independently of each other hydrogen, halogen or cyano. The invention also relates to new pyridoquinolones of the formula I. The colorings obtained with (I) have a yellow hue, a very high tinctorial strength which does not significantly change even in the event of prolonged processing and residence times, high saturation, high dispersibility, good overpainting, migration, wet, rub, light and weather resistance and in particular excellent heat stability.
