Abstract

Surface-treated pigments are described. Surface treatment allows for ease of disperse-ability of pigments into monomers that are commonly utilized in energy-curable inkjet inks. The resulting pigment dispersions have low viscosity and high pigment loading. Inks made from these dispersions have properties of small particle size, high filter rates, low viscosity and high chroma. The surface-treated pigments facilitate excellent stability of ink viscosity and filterability after accelerated oven-aging. Surface treatments have a chemical similarity but are optimized for each pigment. The range covers carbon black, phthalocyanine blue, arylide yellow, nickel azo yellow, and quinacridone magenta.
