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.
