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; and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.

Processes for preparing diacryl-functional compounds are provided. Processes include reacting AB.sub.2 monomers with acryloyl halides, and then further reacting with long-chain, mono-functional aliphatic compounds to form long-chain diacrylates. Further processes include reacting difunctional tic compounds with acrylic acid to form difunctional diacrylate, and diacrylamide compounds.
