Abstract
Antioxidants used for overcoat layers and processes for making the same. The present process for making the antioxidant has proven to be repeatable, cheaper, faster and safer than conventional processes. In particular, the present process uses a different solvent system where crude bis(4-diethylamino-2-methylphenyl)-(4-diethylaminophenylmethane) is dissolved in methylethyl ketone at room temperature, followed by product precipitation in a warm mixture of ethanol and water.
