Abstract

Disclosed herein are sacrificial coating compositions comprising at least one hydrophilic polymer; at least one hygroscopic agent; at least one surfactant; at least one non-reactive silicone release agent; and water. In certain embodiments, the at least one non-reactive silicone release agent is chosen from polyether modified polysiloxane and nonreactive silicone glycol copolymers. In certain embodiments, the at least one non-reactive silicone release agent may be present in an amount ranging from about 0.001% to about 2%, based on the total weight of the composition, such as from about 0.03% to about 0.06%. 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.
