easy dispersing pigment compositions which contain, in addition to pigments, aromatic compounds

摘要

Easily dispersible preparations of organic pigments are obtained by coating the pigment particles with essentially colorless aromatic compounds having a molecular structure being similar to that of the pigment and having an aliphatic chain of more than 5 carbon atoms. These preparations are stable to flocculation and useful for pigmenting hydrophilic and hydrophobic media.
