| abstract |
The present invention relates to a modified colored pigment comprising a colored pigment having an attached organic group. The organic group is attached to the colored pigment via at least one carbon atom of a C—C single bond or double bond, wherein the C—C single bond or double bond is not a component of an aromatic system. The organic group further comprises at least one activating group on at least one carbon atom of the C—C single bond or double bond. A method of preparing a modified colored pigment is also disclosed, as are aqueous and non-aqueous dispersions, e.g., including ink jet inks, comprising the modified colored pigments. |
