Trisazo dye, process for producing the same and aqueous ink composition containing the same |
| abstract |
Disclosed is a trisazo dye represented by the formula:n n wherein R¹ and R² independently represent a substituted amino group which is substituted with hydrogen, a hydroxyl group, a carboxyl group, an amino group, an alkyl group having 1 to 4 carbon atoms, a hydroxyalkyl group or an acyl group, or an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms; and R³ is hydrogen, an alkyl or alkoxy group having 1 to 6 carbon atoms; provided that R¹ and R² are not amino groups or substituted amino groups simultaneously. n A process for producing the trisazo dye and an aqueous ink composition containing the trisazo dye are also disclosed. |
