Abstract: Pigmented masonry compositions are provided that include chemically treated carbon black pigments having attached an organic group including an ionic or an ionizable group, the ionic or ionizable group being present at a level from 1.0 to 3.0 ?mol/m2. The compositions exhibit excellent color consistency and jetness and provide consistent color after long term exposure to high levels of moisture.

Abstract: 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.

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.
