摘要：

Important electrothermographic characteristics such as charge acceptance, surface-potential decay with and without exposure to infrared radiations, retention of suface charge, contrast potential and residual potential of pure and sensitized cellulose acetate layers have been investigated. An attempt has been made to explain the results on the basis of electrical properties. Leucomalachite Green (LMG) is found to be very effective in controlling the thermosensitivity in the cellulose acetate layers. Cellulose acetate layer sensitized with 20% by wt of LMG shows a suitable high-contrast potential of 890 v with zero residual potential on heating its surface to 62 degree C and is a suitable material for electrothermographic and related applications.
