ABSTRACT:
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 a substituted pyridine derivative, 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.
