Abstract

An electrolytic recording sheet for use with an eroding anode contains as marking agent in an electrolytically conducting solution an acid of the formula: <FORM:1098346/D1-D2/1> where the carboxyl group is in the 1 or 2 position, the hydroxyl group is ortho to the carboxyl group, and R is meta to the carboxyl group and is hydrogen, lower alkyl, -CH2Z or -CH(CH3)Z, where Z is: <FORM:1098346/D1-D2/2> where the carboxyl group is in the 1 or 2 position, the hydroxyl group is ortho to the carboxyl group and the Z radical is attached to the carbon atom in the position that is meta to the carboxyl group. The solution may contain as electrolyte a chloride, sulphate or nitrate of an alkali metal, and may also contain a solubilizer for the marking agent, e.g. glycerine, ethylene glycol, propylene glycol, trimethylol-propane or mannitol.
