Abstract
An imaging element is disclosed comprising a support, an imaging layer, and an outermost protective layer on at least one side of the support which comprises a lubricant and an additive which is immiscible with and more surface active than the lubricant, wherein the lubricant is present in an amount of at least 5 mg/m,and the additive is present in an amount of at least 25 wt percent relative to that of the lubricant, the amount of additive being effective to increase the coefficient of friction for the outermost layer after coating and drying thereof relative to that obtained in the absence of the additive material. Imaging elements comprising highly lubricated protective outermost layers in accordance with the invention advantageously provide increased scratch and wear resistance, while the presence of an additive which is immiscible with and more surface active than the lubricant surprisingly has been found to increase the coefficient of friction to provide good manufacturability of the imaging element.
