There are certain performance requirements placed on dye-based colorants for inkjet ink applications. These include high color strength and bright shade, long-term storage stability, high light and water fastness. Moreover, metal-free derivatives are preferable from an environmental standpoint. Reactive dyes are intrinsically bright, with moderate fastness properties and are less harmful to human. However, this type of dye has poor long-term storage stability, owing to reactive group hydrolysis. This reaction causes dye precipitation, leading to clogging and damaging to print head and shade changes problems.Dye with carboxyl group have been studied have high water fastness performance [1,2]. In this paper, a series of black dye composition is discussed which navy component contains carboxyl groups and demonstrates improved water and light fastness. These compositions are readily soluble in aqueous solutions shows good printing performance.
