| titleOfInvention | AZOPIGMENT COMPOSITION WITH IMPROVED HEAT RESISTANCE AND TRANSPARENCY OF DRY INK. |
| abstract | Diaryl pigments having excellent dried ink transparency and improved thermal stability of treatment are prepared by coupling a 4,4 'diaminobiphenyl with bisdiazotized substitution with acetoacetanilides and / or pyrazolinones, in the presence of an added amount of one or more substituted aromatic amines containing at least one substituent of sulfonic or carboxylic acid, or their salts. Pigments have better tolerance to variations in drying temperatures and high drying temperatures. They have better transparency when present in dried ink formulations. |
