Abstract
Abstract A delaminating coating for use in a thermal transfer system is provided that possesses both delaminating properties and antistatic properties. This delaminating coating can be used on a donor sheet or an intermediate carrying sheet of a thermal retransfer system. The preferred delaminating/antistatic coating is formed from a composition of a vanadium oxide colloidal dispersion.
