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.
一种墨水组成物,例如非极性液体或相变(固体)墨水组成物,包括非极性载体和纳米颜料粒子组成物。纳米颜料粒子组成物包括苯并咪唑酮颜料和一个大体积的立体阻碍剂化合物,它是一种芳香酸的烷基衍生物,与苯并咪唑酮颜料非共价结合。存在关联稳定剂限制颗粒生长和聚集的程度,以获得纳米颜料粒子。
