C09B68/463 - CPC Classification

Classification description:

Organic pigments surface-modified by grafting, e.g. by establishing covalent or complex bonds, in order to improve the pigment properties, e.g. dispersibility or rheology characterised by the chemical nature of the attached groups; Aromatic cyclic groups Substituted aromatic groups
