    摘要： A pigment dispersion comprising a colour pigment represented by formula (I) wherein, X1 to X4 are independently selected from the group consisting of hydrogen and a halogen atom, R1 to R10 are independently selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, and an ethoxy group, 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 90% of the molecular weight of the colour pigment, wherein the at least one pending chromophore group is a chromophore group occurring as a side group on the polymeric backbone and not a group in the polymeric backbone itself or occurring solely as an end group of the polymeric backbone, and the at least one pending chromophore group is represented by formula (II) wherein, one of L1, L2 or L3 is the linking group and is selected from the group consisting of an aliphatic group, a substituted aliphatic group, an unsaturated aliphatic group and a substituted unsaturated aliphatic group; L1, L2 and/or L3, if not representing the linking group, are independently selected from the group consisting of hydrogen, an alkyl group, an alkenyl group, an alkoxy group, a carboxylic acid group, an ester group, an acyl group, a nitro group and a halogen; AR1 and AR2 represent an aromatic group; and n represents the integer 0 or 1. The pigment dispersion can be advantageously used in inkjet inks. Also disclosed are methods for preparing the inkjet ink.

    摘要： A pigment dispersion comprising a colour pigment and a polymeric dispersant having at least one pending chromophore group covalently bound to the polymeric backbone of the polymeric dispersant through a linking group wherein the at least one pending chromophore group is a derivative from a colour pigment selected from the group consisting of monoazo pigments, disazo pigments, β-naphtol pigments, naphtol AS pigments, azo pigment lakes, benzimidazolone pigments, disazo condensation pigments, metal complex pigments, isoindolinone pigments, isoindolinine pigments, phthalocyanine pigments, quinacridone pigments, diketopyrrolo-pyrrole pigments, thioindigo pigments, anthraquinone pigments, anthrapyrimidine pigments, indanthrone pigments, flavanthrone pigments, pyranthrone pigments, anthanthrone pigments, isoviolanthrone pigments, aluminium pigment lakes, dioxazine pigments, triarylcarbonium pigments and quinophthalone pigments; the at least one pending chromophore group is a chromophore group occurring as a side group on the polymeric backbone and not a group in the polymeric backbone itself or occurring solely as an end group of the polymeric backbone; the linking group consists of all the atoms between the polymeric backbone and the first atom of the aromatic group by which the pending chromophore group is linked to the polymeric backbone; the polymeric dispersant has a polymeric backbone with a polymerization degree between 5 and 1000; and at most 30 % of the monomer units of the polymeric backbone have a pending chromophore group. The pigment dispersion can be advantageously used in inkjet inks. Also disclosed is a method for preparing the pigment dispersion comprising the step of preparing the polymeric dispersant by copolymerizing a monomer already containing the pending chromophore group.
