UV curable coatings containing dual phase filler-polymer compositions with high resistivity, low dielectric constant, good optical density, and controlled electrical resistivity are described, and cured coatings or films formed thereof, along with their use in black matrix, black column spacers, and other light shielding coating elements in LCD. Devices having these black matrices, black column spacers, and/or other light shielding coating elements, and methods of preparing and making these various materials and products are also described.

Coatings having filler-polymer compositions with combined low dielectric constant, high resistivity, and optical density properties and controlled electrical resistivity, devices made therewith, and methods for making same

The invention provides composite particles comprising core particles having organosilica particles disposed about the core particles. The invention also provides a process for making the composite particles.

Composite particles and a process for making the same

An aqueous 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 resulting coatings exhibit excellent viscosity, color, hiding power and stability.

Carbon black for waterborne coatings

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.

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.

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 pK&#x3c;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.
