ABSTRACT:
A nanoscale pigment particle composition includes an organic benzimidazolone pigment, and a sterically bulky stabilizer compound, wherein the benzimidazolone pigment associates non-covalently with the sterically bulky stabilizer compound that is an alkylated derivative of an aromatic acid; and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale pigment particles.
