  • Publication number: 20140126936
    Abstract: Disclosed herein are resistive composites comprising at least one resin; at least one carbon black having a surface hydrophobically modified with at least one organic group, the at least one organic group having a molecular weight of the composite of 4000 or less and comprising the formula —X(G)-, wherein X is directly attached to the at least one carbon black and is selected from arylene, heteroarylene, and alkylene, G is a substituent of X, and —X(G)- is nonionic; and wherein the resistive composite has a volume resistivity, volume fraction, XCB, of the at least one carbon black in the coating, where Rv is at least 106 ohm-cm; and log Rv has a substantially linear relationship with XCB when XCB is varied from 0.1 to 0.5. Also disclosed are coatings made from such composites, such as coatings for rollers/belts for office automation machines, and methods of making such coatings.

  • Patent number: 8697778
    Abstract: The present invention relates to a black matrix formed by applying a curable coating composition onto a substrate to form a curable coating, curing the curable coating imagewise to form a coating, and developing and drying the coating. The curable coating composition comprises a vehicle, a curable resin, and at least one modified pigment comprising a pigment having attached at least one organic group having the formula -X-I or -X-NI, wherein X, which is directly attached to the pigment, represents an arylene or heteroarylene group, an alkylene group, an aralkylene group, or an alkarylene group, I represents a non-polymeric group comprising at least one ionic group or at least one ionizable group, and NI represents a non-polymeric group comprising at least one nonionic group. The curable coating composition, curable coating, and cured coating are also described. Also disclosed is a method of controlling the resistivity of a coating.

  • Patent number: 8585816
    Abstract: The present invention relates to dispersions comprising particulate materials and a solvent, with an optional dispersant. The solvent has a low dielectric constant, and the particulate material is present at high loading levels. The resulting dispersion has been found to be stable and have a low viscosity, even at high particulate material loadings. Various uses for these dispersions are also disclosed.

  • Patent number: 7972428
    Abstract: A process for preparing a modified pigment having attached at least one organic group is described. This process comprises the step of combining, in any order, a colored pigment, an aromatic amine, a base, and an aqueous medium to form a mixture, and then combining the mixture and a diazotizing agent to form the modified pigment. The aromatic amine comprises at least two carboxylic acid groups, preferably being vicinal. The resulting modified colored pigment can be used in an inkjet ink composition to produce printed images having good overall properties.
