An advanced type of TA (Thermo Autochrome) paper with high image stability, named “Printpix Paper” has been released. The light stability, the dark stability and the stability with respect to gases were studied to understand the image stability of the Printpix paper. The light stability under normal display conditions was predicted by means of an accelerated light test which utilized a fluorescent light and a xenon arc light. The dark stability at room temperature was predicted by an accelerated thermal test based on Arrhenius methodology. The amount of image fading that actually occurred indoors with regard to TA paper was also confirmed by the test. It showed that the amount of image fading on TA paper was not influenced by gases such as ozone, and the result of the accelerated light test corresponded to the actual image fading which occurred indoors. In this paper the authors will demonstrate that the image stability of the Printpix paper has been remarkably improved in comparison to previous TA paper and the practical image stability of the Printpix paper is satisfactory.
