Abstract

AbstractA solution cast layer of ethyl cellulose on aluminium substrate shows high charge acceptance on corona charging. Its surface potential decay characteristics are studied at room temperature and at higher temperatures. Addition of a thermosensitive dye in the polymer matrix shows enhanced contrast potential at constant IR exposure. Optimum conditions for suitability of the polymer in electrothermography is determined by studies on different weight proportions of dye. The effect of layer thickness on surface potential characteristics is also investigated.
