The present invention provides a pigment ink formulation containing a wax emulsion is disclosed. The wax emulsion comprises a specific wax and surfactant combination. In particular, the wax comprises a linear polyethylene wax and the surfactant is an alkyl ether carboxylate. The wax emulsion can be made by any process for preparing emulsions used by those skilled in the art such as typical homogenization methods. Applicants have discovered that such a wax emulsion can not only improve the scratch resistance of pigmented ink, but also improve other handling problems such as scuff and smear.
