Role of Media Polymer Chemistry on Dye / Polymer Interactions and Light Stability of Ink Jet Graphics
Abstract:The chemical environment within the receiving layer(s) is known to influence the permanence of dye-based ink jet graphics. A correlation was observed between dye light fastness and the concentration dependence of UV / VIS absorption in dyed acrylamide and polyvinyl pyrrolidone polymers. This has been interpreted as a consequence of media influenced dye aggregation. Computer modeling of dye polymer interactions supports this interpretation in the case of the polyvinyl pyrrolidone and acrylamide polymers, but suggests other factors can also play a role in the favorable photo stability of polyvinyl alcohol images. The validity of the computer models and dyed polymer techniques employed in understanding dye photo fade are addressed.

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.
