Novel Black Colorants for Ink Jet Applications
In this paper, novel black disazo and tetrazo coppercomplex dyes are presented exhibiting improvements in light stability as compared to metal-free black azo dyes. The improved light fading resistance can be explained by enhanced dye aggregation. Furthermore, novel heavy metalfree black polyazo and polycyclic dyes for industrial ink jet applications have been developed on a pilot scale showing superior light fastness and bar code readability using infrared lasers. Optical as well as light and water fastness characteristics of the novel dyes are compared with commonly used heavy metal-free colorants.

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.
