ANTI-ABRASION INK ADDITIVES CONTAINING REDUCED AMOUNTS OF POLYTETRAFLOUROETHYLENE AND INKS CONTAINING SUCH ADDITIVES

摘要

An anti-abrasion additive for ink formulations includes sintered polytetrafluoroethylene in a reduced amount; a petrolatum; and a high meltin g point microcrystalline wax. The additive, when dispersed in an ink, provides the ink with good slip, abrasion resistance, low misting, and mar resistance.
