Abstract (en)
A process for providing permanent images upon substrates and a class of substrates useful therein. Thermal printing means, such as a thermal print head, are employed to raise the temperature of a normally solid, non-tacky material above its melting temperature and provide a latent liquid image area on a substrate. The image area is then developed by contacting it with a dry imaging powder that becomes attached thereto. Sufficient pressure is applied to the image area to fix the powder thereto and provide an essentially permanent image. The process is useful wherever it is desired to generate images from electronic data sources such as computers, fascimile transceivers, chart recorders, teleprinters, etc., and provide such images in essentially permanent form.
