| titleOfInvention | Mixed coupled azo pigments |
| abstract | A mixed coupled azo pigment is described which is prepared from (A) a mixture comprising from about 5 to about 95% by weight of each of two or more diazonium components derived from aromatic amines provided that: (A-1) if one of the aromatic amines in the mixture contains a carboxamide group, then the other amine in the mixture is a diaryldiamine; or (A-2) the mixture comprises about 20 to about 80% of each diazonium component when one of the aromatic amines contains a carboxylic acid, sulfonic acid, or salt thereof, and the other aromatic amine is a diaryldiamine; or (A-3) the mixture comprises from about 30 to about 70% of each of the diazonium components when the aromatic amines in the mixture contain a nitro group; and (B) an organic coupling component, provided that when the coupling component is a 2-naphthol characterized by formula (I), wherein R1 is hydrogen or -COOH, the mixture (A) may comprise from about 5 to about 95% by weight of each of two or more diazonium components derived from aromatic amines containing carboxamide groups, and the mixture does not have to contain a diaryldiamine. The pigments of the invention provide unique performance characteristics in inks, plastics, coatings, etc. |
