ABSTRACT:
An electrosensitive recording sheet consists of an electroconductive material of cuprous iodide, an electrosensitive color forming material, a binder and a support. A color forms in the recording sheet in response to an electric signal when an electric current flows therein. The cuprous iodide is whitened by adding an alkaline substance thereto, so as to only slightly increase the resistance of the cuprous iodide and to increase the contrast of recorded mark and the ordinary appearance of the recording sheet.
