Abstract:

Novel pigment colorant sets have been developed using Cabot's proprietary surface treatment technology. The new technology involves treatment of the pigment surface with reactive precursors. Subsequent secondary and tertiary reactions with pre-formed polymers and oligomers yields materials with unique physico-chemical properties. The combination of unique chemistries and advanced purification methods lead to well characterized pure pigments, void of free polymers and impurities.

These methods allow customization of the pigment surface that can create new levels of pigment performance required for demanding digital printing applications. This includes enhanced formulation flexibility, new levels of colloidal stability, tuned colorant-media interactions, and increased permanence. A discussion of the various chemical approaches and material performance properties will be presented.

  • 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.
