| Title of Invention | NEW BISAZOMETHINE PIGMENTS FROM HOMOPHTHALIMIDE DERIVATIVES |
|---|---|
| Abstract | The present invention encompasses new bisazomethine pigments of formula I, prepared from homophthalimides and different aromatic diamines (ex. 4,4’-diaminobenzanilide, 4,4’-diaminosulfanilide, 4,4’-diaminoazobenzene, paraphenylenediamine, 2,5-dichloroparaphenylenediamine etc.) in the presence of triethylorthoformate using different solvents. Where X = part of an aromatic diamine, R=H, C1-6 alkyl, C6-10 aryl, C7-10 aralkyl, -CH₂CH₂OH, -CH₂CH₂CN etc. |
