Abstract
Abstract A recording material including at least a liquid dispersion medium and an electrolyte contained therein; the electrolyte providing substantially no halogen ion in the liquid dispersion medium under electrolytic dissociation; the recording material being capable of changing its adhesiveness when imparted with a voltage by means of a pair of electrodes, thereby to selectively adhere to either one of the pair of electrodes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
A recording material, comprising at least a liquid dispersion medium in an amount of 40-95 wt % of the recording material and an electrolyte contained therein in an amount of 0.05 wt. part to the saturation solubility with respect to 100 wt. parts of the liquid dispersion medium; said electrolyte providing substantially no halogen ion in the liquid dispersion medium under electrolytic dissociation; said recording material being adhesive under no voltage application and losing its adhesiveness on one of a pair of electrodes when imparted with a voltage by means of the pair of electrodes, so that the recording material is selectively attached to the other of said pair of electrodes on voltage application.
Claim 2
Dependent Claim
114 words
A recording material, comprising at least a liquid dispersion medium in an amount of 40-95 wt % of the recording material and an electrolyte contained therein in an amount of 0.05 wt. part to the saturation solubility with respect to 100 wt. parts of the liquid dispersion medium; said electrolyte providing substantially no halogen ion in the liquid dispersion medium under electrolytic dissociation; said recording material being adhesive under no voltage application and losing its adhesiveness on one of a pair of electrodes when imparted with a voltage by means of the pair of electrodes, so that the recording material is selectively attached to the other of said pair of electrodes on voltage application.
Claim 3
Dependent Claim
17 words
A recording material according to claim 1, wherein said liquid dispersion medium comprises a polyhydric alcohol-type solvent.
Claim 4
Dependent Claim
14 words
A recording material according to claim 2, wherein said polyhydric alcohol-type solvent comprises glycerin.
Claim 5
Dependent Claim
19 words
A recording material according to claim 2, wherein said liquid dispersion medium comprises a polyhydric alcohol-type solvent and water.
Claim 6
Dependent Claim
44 words
A recording material according to claim 1, wherein said electrolyte comprises one or more species selected from the group consisting of lithium borofluoride (LiBF 4 ), sodium hexafluorophosphate (NaPF 6 ), ammonium hexafluorophosphate (NH 4 PF 6 ), and sodium acetate (CH 3 COONa).
Claim 7
Dependent Claim
30 words
A recording material according to claim 1, which contains 0.1 wt. part to the saturation solubility of said electrolyte with respect to 100 wt. part of the liquid dispersion medium.
Claim 8
Dependent Claim
30 words
A recording material according to claim 1, which contains 1.0 wt. part to the saturation solubility of said electrolyte with respect to 100 wt. part of the liquid dispersion medium.
Claim 9
Dependent Claim
21 words
A recording material according to claim 1, which comprises the liquid dispersion medium, the electrolyte and inorganic or organic fine particles.
Claim 10
Dependent Claim
15 words
A recording material according to claim 8, wherein said fine particles comprises swelling fine particles.
Claim 11
Dependent Claim
21 words
A recording material according to claim 1, which further comprises a crosslinked substance impregnated with said liquid dispersion medium and electrolyte.
Claim 12
Dependent Claim
68 words
An image forming method, comprising: providing a recording material according to claim 1; supplying the recording material between a pair of electrodes, at least one of which is a plate comprising an electroconductive portion and an insulating portion; and applying a voltage between the pair of electrodes so that said plate may be a cathode, thereby to attach the recording material to the insulating portion of the plate.
