Fine Particle Pigment Concentrates for Ink Jet Printing Inks
  DOI :  10.2352/ISSN.2169-4451.1998.14.1.art00022_1  Published OnlineJanuary 1998

Aqueous, low viscosity, stable pigment concentrates suitable for formulating Ink Jet printing inks have been realized based on selected fine grade pigment preparations. This paper deals with the prerequisites for successful concentrate technology, such as:• fine grade pigment preparation by combining salt milling and kneading technologies• reaching a high pigment load while maintaining low viscosity• the three stages of successful dispersion technology (wetting, desagglomeration and dispersion stability)• the suppression of particle flocculation.Pigment chromophores usable for Yellow, Cyan and Magenta process colors are discussed.
