    摘要： The present invention is an imaging element which includes a support, an image forming layer superposed on the support; and at least one layer superposed on the support. The at least one layer superposed on the support is formed from a non-aqueous coating composition of a composite wax particle composed of a wax phase and a non-crosslinked polymer phase and an organic solvent. The wax phase includes a wax having a melting point of greater than 30° C. The wax comprises greater than 80% by weight of the wax phase. The wax phase to non-crosslinked polymer phase ratio is greater than 30/70 and less than 90/10.
