    摘要: Nano-sized phthalocyanine pigment particles include a phthalocyanine chromogen structure as the main component, and a substituted soluble metal-phthalocyanine dye as a minor component that is associated non-covalently with the phthalocyanine chromogen structure, wherein the presence of one or more sterically bulky substituents on the substituted soluble metal-phthalocyanine dye limits an extent of pigment particle growth and aggregation, to afford nano-sized pigment particles.

    摘要: Nanoscale particles of benzimidazolone pigments are made by providing one or more organic pigment precursor(s) to a benzimidazolone pigment, providing a solution or suspension of a sterically bulky stabilizer compound that associates non-covalently with a benzimidazolone moiety on one of the pigment precursors, wherein the sterically bulky stabilizer compound is selected from the group consisting of substituted pyridine derivatives, alkylated benzimidazolone compounds, alkylated derivatives of aromatic acids, and mixtures thereof, and carrying out a coupling reaction to form a benzimidazolone pigment composition, whereby one or more functional moieties on the benzimidazolone pigment is non-covalently associated with the sterically bulky stabilizer, so as to limit an extent of particle growth and aggregation and results in nanoscale pigment particles.

    摘要: An ink composition, such as a nonpolar liquid or phase change (solid) ink composition, that includes a non-polar carrier, and a nanoscale pigment particle composition. The nanoscale pigment particle composition includes a benzimidazolone pigment and a sterically bulky stabilizer compound, which is an alkylated derivative of an aromatic acid, associated non-covalently with the benzimidazolone pigment. The presence of the associated stabilizer limits an extent of particle growth and aggregation, to afford nanoscale pigment particles.
