PIGMENT DISPERSIONS WITH POLYMERIC DISPERSANTS HAVING PENDING CHROMOPHORE GROUPS.

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.

Reaction of Triazene 1-Oxides: Novel Synthesis of Solid Arenediazonium Chlorides

Treatment of 1,3-diaryltriazene 1-oxides with oxalyl chloride in dry toluene at room temperature gives only solid arenediazonium chlorides; however, treatment with acetyl and benzoyl chlorides does not afford the corresponding diazonium chlorides.
