Pumpable Anti-Abrasion Ink Additives and Printing Inks Containing Such Additives

摘要

An improved pumpable anti-abrasion/slip ink additive is disclosed comprising a mixture of polytetrafluoroethylene and polyalphaolefin. As an alternative, a dditional material, such as phenolic resins and oils can be added to the mixture. The additives permit the less costly manufacture of printing inks, most particularly heat set ink s and results in print which has improved rub, slip and anti-mar characteristics.
