Abstract: Composition and process for preparing darkened headlap, the composition having base granules treated with a suspension containing: a hydrocarbon oil or a hydrocarbon/drying oil mixture; carbon black; and an organosilicon compound of formula I RnSi(OR′)4−n wherein R is a large organic group, such as a long-chain alkyl group, R′ is lower alkyl of 1-6 carbons, and n is 1-3, or a siloxane polymer of two or more silane units.

Abstract: Conductive coating compositions containing a pigment-grade carbon, a resin and a solvent. The compositions are useful as primers and coatings.

Abstract: Anti-mist compounds adapted to inhibit the misting tendencies of printing inks on high speed printing presses are prepared by mixing chrysotile particles having an average particle size exceeding about 0.01 inch and preferably ranging from 0.1 inch to about 0.5 inch, with a printing ink vehicle to provide a mixture in which the particles of chrysotile are wetted by the vehicle and which preferably contains above about 20% by weight of chrysotile. The mixture is sheared, as on a three roller mill for example, to grind the chrysotile into micro-fibrous particles and to distribute the micro-fibrous particles uniformly throughout the vehicle. By employing chrysotile particles having the aforesaid particle size range, workable compound mixtures containing 35% or more by weight of chrysotile may be obtained. The compound mixtures produced are useful to inhibit the misting tendencies of printing inks without causing flatting or emulsification of the ink, and without appreciably affecting ink viscosity.
