New black dye for inkjet ink application
Abstract:There are certain performance requirements placed on dye-based colorants for inkjet ink applic ations. These include high color strength and bright shade, long-term storage stability, and high light 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 damage to print head and shade changes problems.
In this paper, a modified black dye is discussed. It is derived from Everzol® Black GSP, and demonstrates improved storage stability and color strength. In addition, it is metal-free and resulting prints display improved light fastness. This dye is readily soluble and aqueous solutions shows good printing performance.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
