“Functionalized inorganic polymer salts” as Charge Control Agents
Abstract:The new class of “functionalized inorganic polymer salts” (FIP) provides Charge Control Agents (CCAs) that are synthesized from natural raw materials and that are heavy metal free. The concept of FIP will be described by the example of hydrophobically modified layered metal oxides (HMLM). HMLMbased charge control agents are colorless and consist of an inorganic backbone that is treated with organic counter ions. By variation of the counter ions these products can be modified for different toner systems. These can be classical physically prepared toners but also various chemically prepared toners. An overview of the chemistry of HMLM is provided and examples of HMLM-CCAs and their properties in the solid state and in dispersion are discussed.

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.
