Abstract
A thermosensitive image-forming element is comprised of at least one image-forming layer and a biaxially-oriented heatset poly(ethylene terephthalate) film support which is capable of resisting dimensional distortion resulting from the combined effects of tension and heat. The element is processed by application of heat sufficient to form a visible image while maintaining the element under tension in its longitudinal dimension and no tension in its transverse dimension.
