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.

Abstract: 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.

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.
