Description

technical field

[0001] The present invention relates to a class of diazo water-soluble dye compounds with improved application characteristics, excellent comprehensive performance and low synthesis cost and their uses, especially related to excellent performances such as light fastness, gas resistance (ozone resistance), water resistance, etc. Disazo dyes, black dyes and black ink compositions thereof. Background technique

[0002] In recent years, with the popularization of computers, inkjet printers have become more common not only in offices but also in homes.

[0003] The inks used in inkjet printing mainly include water-based inks and oil-based inks, among which water-based inks have advantages in terms of preparability, operability, safety and odor. For the water-based ink of ink-jet printing, it is required that its coloring material has high solubility in water and organic solvents, the printing color density is high, the color tone is good, non-toxic and cheap, and...
