Abstract
A recording material (ink) showing a selective adhesiveness to one of a pair of electrodes applying a voltage to the recording material, is constituted by dissolving an electrolyte in a solvent. The recording material is provided with an improved stability against environmental changes, particularly against a humidity change, if the solvent is at least partly constituted by a reaction product between a ring-opening product of an alkylene oxide R--O.sub.n and glycerin or phenol, wherein R is an alkylene group and n is an integer.
Claims9
A recording material comprising at least a solvent and an electrolyte and showing a change in adhesiveness when placed between a pair of electrodes under voltage application to adhere substantially selectively to one of the electrodes, wherein said solvent comprises a reaction product between a ring-opening product of an alkylene oxide --R--O).sub.n and glycerin or phenol, wherein R is an alkylene group having 2-10 carbon atoms and n is an integer;
- wherein the reaction product is contained in a proportion of 20-80 wt. parts per 100 wt. parts of the recording material;
- and wherein the electrolyte is contained in a proportion of 0.0001 mol per liter of the solvent to the saturation solubility.
