Polymeric Dye Inkjet Colorants with High Waterfastness
Abstract:Ink compositions used in inkjet printers can be classified as either pigment based, in which the colorant exists as pigment particles suspended in the ink composition, or as dye based, in which the colorant exists as a fully solvated dye species that consists of one or more dye molecules. Commonly used dye-based inks suffer poor waterfastness and low durability against wet rub abrasion, which can render text and universal packaging code information illegible. A subclass of dye-based inks may contain polymeric colorants in which a chromophore is covalently bound to a polymer structure. This presentation describes our work with a class of polymeric colorants that can be utilized in ink compositions for inkjet printing that are stable, do not adversely affect the performance of an inkjet nozzle, and deliver images with high waterfastness.

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.
