Abstract: Disclosed herein are sacrificial coating compositions comprising at least one polymer chosen from polyvinyl alcohol and polyvinyl alcohol copolymers, a wax emulsion comprising at least one wax, at least one surfactant, at least one hygroscopic agent, and water. In certain embodiments, the at least one wax in the wax emulsion has a melting point approaching but just below the ink transfer temperature, such as, for example, a melting point ranging from about 50° C. to about 150° C. Also disclosed herein is a blanket material suitable for transfix printing comprising a sacrificial coating composition, as well as an indirect printing process comprising a step of applying a sacrificial coating composition to a blanket material.
