PIGMENT DISPERSIONS WITH POLYMERIC DISPERSANTS HAVING PENDING CHROMOPHORE GROUPS. |
摘要 |
A pigment dispersion comprising a colour pigment represented by formula (I) wherein, R1 to R10 are independently selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, - CF<SUB>3</SUB> , -COOH, -COOCH<SUB>3</SUB>; -SO<SUB>2</SUB>NH-C<SUB>6</SUB>H<SUB>5</SUB>, -CONH-C<SUB>6</SUB>H<SUB>5</SUB>, -CONH-C<SUB>6</SUB>H<SUB>5</SUB>-CONH<SUB>2</SUB> and -CONH<SUB>2</SUB>; and a polymeric dispersant having via a linking group covalently linked to its polymeric backbone at least one pending chromophore group which has a molecular weight smaller than 95% of the molecular weight of said colour pigment. The pigment dispersion can be advantageously used in inkjet inks. |
