Modified carbon products and inks and coatings containing modified carbon products

Abstract: A modified carbon product is described which comprises carbon having attached at least one organic group. The organic group comprises a) at least one aromatic group or a C1 -C12 alkyl group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The aromatic group or the C1 -C12 alkyl group of the organic group is directly attached to the carbon and the organic group is present at a level of from about 0.10 to about 2.5 micromoles/m2 of the carbon used based on CTAB or t-area of the carbon or in an amount such that the modified carbon product has a residue value of more than about 5 wt %. Also described are aqueous and non-aqueous inks and coatings containing the modified carbon product. A method to increase the flow of an ink, as measured by glass plate flow, by incorporating the modified carbon product as part of the ink is also disclosed. Lastly, non-aqueous ink and coating formulations are described which contain an appropriate solvent and a modified carbon product comprising carbon having attached at least one organic group, wherein the organic group comprises a) at least one aromatic group or C1 -C12 alkyl group, and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group, wherein the organic group is present in any amount.

Modified colored pigments and ink jet inks, inks, and coatings containing modified colored pigments

Abstract: A modified colored pigment is described which comprises colored pigment having attached at least one organic group. The organic group comprises a) at least one aromatic group or a C 1 -C 12 alkyl group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The aromatic group or the C 1 -C 12 alkyl group of the organic group is directly attached to the pigment and the organic group is present at a treatment level of from about 0.10 to about 4.0 micromoles/m 2 of the pigment used based on nitrogen surface area of the pigment. Also described are aqueous and non-aqueous inks and coatings and ink jet ink compositions containing the modified colored pigment. A method to increase the flow of an ink is also disclosed as well as a method to improve the waterfastness of a print imaged by an ink composition. Also, other ink jet ink compositions are described which comprise an aqueous or non-aqueous vehicle and a colored pigment having attached an organic group having the formula: Ar--R 1 (I) or Ar'R 3 R 2 (II) wherein Ar is an aromatic group and Ar' is an aromatic group.

Chemical mechanical polishing slurry useful for copper/tantalum substrate

Abstract: The present invention is a first CMP slurry including an abrasive, an oxidizing agent, a complexing agent, a film forming agent and an organic amino compound, a second polishing slurry including an abrasive, an oxidizing agent, and acetic acid wherein the weight ratio of the oxidizing agent to acetic acid is at least 10 and a method for using the first and second polishing slurries sequentially to polish a substrate containing copper and containing tantalum or tantalum nitride or both tantalum and tantalum nitride.

Ink jet ink formulations containing modified carbon products

Abstract: There is disclosed an aqueous ink jet ink composition comprising an aqueous vehicle and a modified carbon product containing carbon having attached at least one organic group. The organic group comprises a) at least one aromatic group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. The organic group having an aromatic group is directly attached to the carbon by the aromatic group. The organic group may comprise a) at least one C1-C12 alkyl group and b) at least one ionic group, at least one ionizable group, or a mixture of an ionic group and an ionizable group. Ink jet recording methods applying an ink jet ink of the present invention are also described.

Composition and slurry useful for metal CMP

Abstract: A chemical mechanical polishing composition comprising an oxidizing agent at least one catalyst having multiple oxidation states, and at least one stabilizer, the composition being useful when combined with an abrasive or with an abrasive pad to remove metal layers from a substrate.
