Process for the manufacture of metal complexes of isoindoline azines |
| abstract |
The invention relates to a simplified process for the manufacture of 1:1 metal complexes of isoindoline azines of the formula <IMAGE> (1) wherein R is hydrogen, alkyl or aryl, Q contains an isocyclic or heterocyclic radical, acyl, carbamoyl or thiocarbamoyl, and Y is the radical of an active methylene group or aromatic amine, which comprises reacting a compound HQ or a hydrazone with an ortho ester or amidine in the presence of a metal donor at elevated temperature in a polar solvent. Pigments made by this process are lightfast and are useful in coloring plastics. |
