摘要:
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.

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.

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.
