| titleOfInvention | Trisazo compound, ink composition, recording method and colored body |
| abstract | Disclosed is a dye compound for black ink which has high solubility in media composed mainly of water and which is stable even when a high-concentration aqueous solution and ink are stored over a long term. The density of printed images is very high, and even if a high-concentration solution is used for printing, no bronzing occurs in the images, and black recorded images are provided with which all aspects of printed image durability, particularly light resistance and ozone gas resistance, are excellent. Also disclosed is an ink composition thereof. Trisazo compounds represented by general formula (1) or tautomers thereof or salts thereof are used as said dye compound for black ink. n n n n n n n n n n In formula (1), group A represents a 2-naphthothiazolyl group, R 1 represents a substitutable C1 to C4 alkyl group or the like, R 2 represents a cyano group or the like, R 3 and R 4 independently represent a hydrogen atom, a sulfo group, or the like, R 5 to R 7 independently represent a hydrogen atom, a substitutable C1 to C4 alkyl group, or a substitutable C1 to C4 alkoxy group, or the like, and R 8 to R 10 independently represent a hydrogen atom, a substitutable C1 to C4 alkyl group, a substitutable C1 to C4 alkoxy group, a substitutable C1 to C4 alkylthio group, or the like. |
