A donor element is described for use in a thermal imaging process. The donor element includes a support: a heating layer; a colorant containing transfer layer; and an overcoat layer comprising a wax having a melting point ranging from about 30� C. to about 350� C. Typically the wax is a natural vegetable wax, a mineral wax or a synthetic wax.
