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.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
