| titleOfInvention | Use of pyridoquinolone derivatives as pigments |
| abstract | 3-16113/+ Use of pyridoquinolone derivatives as pigments Abstract of the Disclosure Process for mass-colouring high molecular weight or-ganic material, which comprises using a compound of the formula I (I) in which one of R1 and R2 and one of R3 and R4 are, inde-pendently of each other, hydrogen, C1-C12-alkyl or benzyl and the other two radicals are, independently of each other, unsubstituted or halogen-, trifluoromethyl-, cyano-, C1-C12-alkyl-, -OR5-, -SR5-, -COR6- or -SO2R6-substituted phenyl, biphenyl or naphthyl or a 5- or 6-membered aromatic hetero-cyclic 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 ben-zene rings, R5 is hydrogen or C1-C12-alkyl, R6 is C1-C12-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 colourings 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 resi-dence times, high saturation, high dispersibility, good over-painting, migration, wet, rub, light and weather resistance and in particular excellent heat stability. |
