Migration images are well known for their use in microimaging. To preserve the original density of the image during use in projectors, etc., the images are over-coated with suitable materials to protect them from not only abrasion but also to the heat produced during use. Certain polymeric materials have been discovered which preserve the image density as well as protect the image from abrasion. In the figure, image density is plotted with respect to temperature in a standard heat-stability test. As shown in the figure, the polysulfone provides superior heat resistance of the image with respect to maintenance of image density while Lexan polycarbonate and Bavick I1 are superior to Krylon.
