    摘要: A method of preparing a pigment includes, in order, the steps of: a) providing a pigment containing a nucleophile group under basic conditions; b) reacting the pigment with a compound according to Formula (I): wherein, X is a halogen atom or a tosylate group, and R1 and R2 independently represent an alkyl group; and c) hydrolyzing the R1-O bond and/or the R2-O bond. The obtained pigments can be used in non-aqueous pigment dispersions.

    摘要: Various modified pigment products are described which are preferably capable of being dispersed in a variety of materials such as coatings, inks, toners, films, plastics, polymers, elastomers, and the like. The modified pigments are pigments having attached groups, such as polymeric groups, onto the pigment by means other than adsorption. A modified pigment product is described comprising a pigment having attached at least one group comprising the formula: —X—[NIon]pR wherein X comprises an aromatic group or an alkyl group, NIon comprises at least one type of non-ionic group, R represents hydrogen or comprises an aromatic group or an alkyl group, and p represents an integer of from 1 to 500. Modified pigment products are also described comprising a pigment having attached at least one alkylene oxide group or at least one polymeric group. In addition, other types of modified pigment products are described as well as their incorporation into inks, coatings, toners, films, plastics, polymers, elastomers, and the like. Methods of making the modified pigment products are also described.

    摘要: 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.
