Abstract
A method of fusing an electrostatographic colored toner image on a transparent support to provide a projection viewable color transparency exhibiting excellent color clarity. The support comprises a polymer layer bearing the color toner image. The toner image and the polymer forming the layer on the support have a loss tangent value of at least 1.6. The transparent element is subjected to fusing in three distinct zones; a fusing zone where it is contacted with a textured fusing member, a cooling zone where contact with the fusing member is maintained and the toner image is cooled and a release zone where the toner image is released from the fusing member at a temperature where no toner image or polymer layer offset occurs.
