Abstract
The present invention relates to a thermal transfer medium which transfers images to a receiving substrate. The thermal transfer medium includes a laminate, having a substrate and a coating having protrusions with a length/width ratio of not less than about 3 and at a density of not less than about 20 protrusions/100 micrometer squared, and a functional layer positioned substantially on the coating. This coating may include an oil. Furthermore, the present invention also relates to a method of making the thermal transfer medium.
