Abstract

PURPOSE: To improve transparency of an image background, by contacting with a solution containing a compound capable of forming a soluble silver complex salt the image recorded and developed on an electrothermo-recording material using a siliver salt of a benzotriazole derivative as a reducible metal compound.
CONSTITUTION: The electrothermo-recording material is prepared by forming on a conductive substrate a conductive composition layer consisting of a binder (a), such as gelatin or cellulose nitrate; a compound (b) of bensotriazoles; a silver salt (c) of compound (b), such as benzotriazole silver or nitrobenzotriazole silver; an organic compound (d) capable of reducing silver salt (c), such as L-ascorbic acid or a catechol derivative; and the like. After this recording material has undergone heat development by electric current, it is dipped in a solution containing a compound capable of forming a soluble silver complex salt, such as thiosulfate or thiocyanate for about 10 seconds to one hour to remove the silver salt of benzotriazole derivative on the background (the parts through which current has not passed) in order to render the background transparent
