Sensient's S.M.A.R.T. 4000 Technology for Self-Dispersed, Polymer-Attached Nano Particle Dispersions for Inkjet Inks
Abstract:The methodology of attaching polymers on the surface of pigments using the S.M.A.R.T. (Surface Modification by Attachment via Radical disproportionation Technology) approach will be discussed. This method allows the “one-pot” attachment of polymers in addition to small molecules such as 4-amino benzoic acid. While the small molecules are attached through the intermediacy of 1,3,5-triazine derivatives, many polymers are amenable to incidental attachment in the presence of the free radicals generated in situ from 1,3,5-triazines species.
The benefits of attaching polymers to pigments include the overriding of the pigment-polymeric dispersant compatibility problems that sometimes occur and having greater flexibility in adjusting the pigment properties for inkjet printing.

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.
