  • Patent number: 9725621
    Abstract: CMP processes, tools and slurries utilize composite particles that include core particles having organosilica particles disposed about the core particles. Using these processes, tools and slurries can enhance removal rates, reduce defectivity and increase cleanability with respect to comparable systems and substrates.
    Type: Grant
    Filed: April 30, 2014
    Date of Patent: August 8, 2017
    Assignee: Cabot Corporation
    Inventors: Qingling Zhang, Bennett Greenwood, Ravi Sharma, Geoffrey D. Moeser, Brian G. Prevo, Mark J. Hampden-Smith
  • Publication number: 20160137866
    Abstract: An aqueoue carbon black millbase, an aqueous carbon black liquid coating, and a method of making the millbase and liquid coating are provided. The carbon blacks are modified carbon blacks that are engineered to be able to be stirred into an aqueous vehicle without high energy milling of the carbon black. The modified carbon blacks include low organic treatment levels and the millbase and liquid coating do not require large quantities of dispersant. The resultant coatings exhibit excellent viscosity, color, hiding power and stability.

  • Patent number: 9238736
    Abstract: The present invention relates to surface modified organic black pigments, surface modified carbon blacks, pigment mixtures and dispersions formed with these pigments, curable compositions, black matrices, and products incorporating them. The surface modified organic black pigment can have attached at least one organic group having the formula -X-Z, wherein X, which is directly attached to the pigment, represents an arylene group, a heteroarylene group, an alkylene group, an aralkylene group, or an alkarylene group, and Z represents at least one ionic group, at least one ionizable group, at least one nonionic group, at least one polymeric group, or any combinations thereof. Also disclosed are carbon black pigment combinations with the surface modified organic black pigments, low dielectric black dispersions, films, and black matrices containing them. Methods of preparing and making these various materials also are provided.

  • Publication number: 20150079514
    Abstract: Disclosed herein is a method of making a modified pigment, comprising: reacting, under Mitsunobu conditions: (a) a first reactant comprising a protonated nucleophile having a pKa<15, and (b) a second reactant comprising a hydroxyl-containing organic group, wherein a pigment is attached to either the first or second reactant. The method further comprises forming the modified pigment having attached an organic species comprising the nucleophile bonded to the organic group, with the net elimination of a proton and a hydroxyl. Also disclosed herein are modified pigments, which can have applications in chemical toners, inkjet ink and electrophoretic ink compositions, black matrix materials, color filters, and coatings.
