ABSTRACT:
An improved pumpable anti-abrasion/slip ink additive is disclosed comprising a mixture of polytetrafluoroethylene and polyalphaolefin. As an alternative, additional 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 inks and results in print which has improved rub, slip and anti-mar characteristics.
