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 an alkylated-benzimidazolone compound, 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.
Claims24
An ink composition comprising:
- a non-polar carrier, and
- a nanoscale pigment particle composition, comprising:
- a benzimidazolone pigment, and
- a sterically bulky stabilizer compound associated non-covalently with the benzimidazolone pigment, wherein the sterically bulky stabilizer compound comprises an alkylated-benzimidazolone compound;
- wherein presence of the sterically bulky stabilizer compound associated with the benzimidazolone pigment limits an extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.
