Abstract
Disclosed is an ink carrier comprising (A) an antioxidant mixture comprising (a) a hindered phenol antioxidant, and (b) a hindered amine antioxidant, (B) a polyalkylene wax, (C) a functional wax, and (D) an ester-terminated amide. The low polarity ink carrier is substantially resistant to phase separation, has excellent thermal stability, resists autocatalytic degradation of the ink composition and a substantial color shift upon standing, and provides enhanced humidity resistance. This ink carrier can be combined with a colorant to produce an ink composition.
