Claims19
An electrophoretic migration imaging recording method comprising the steps of:
- (a) providing an electrically photosensitive imaging layer comprising an electrically photosensitive particulate material having the following general structure:
- ##STR32## wherein R.sup.1 is hydrogen, lower alkyl, lower alkoxy, nitro, halogen, cyano, phenyl, lower alkylsulfonamido or lower alkoxycarbonyl and A.sup.1 is a monovalent and A.sup.2 is a divalent residue of an aniline, 1,2,3,4-tetrahydroquinoline, benzomorpholine or indoline compound attached to the .dbd.CH-- group by an aromatic ring carbon atom in the position para to the aromatic amine nitrogen atom,
- (b) applying an electrical field across said layer;
- and
- (c) exposing said layer to an image pattern of electromagnetic radiation to which said electrically photosensitive material is photosensitive;
- and
- (d) if necessary, at least partially liquifying said layer before, during or after exposure and application of the electric field to permit some migration of said electrically photosensitive material in said layer,
- thereby forming a record of the image pattern of electromagnetic radiation in said layer.
An electrophoretic migration imaging layer comprising an electrically photosensitive particulate material having the structure ##STR44## wherein R.sup.1 is hydrogen, lower alkyl, lower alkoxy, nitro, halogen, cyano, phenyl, lower alkylsulfonamido or lower alkoxycarbonyl and A.sup.1 is a monovalent and A.sup.2 is a divalent residue of an aniline, 1,2,3,4-tetrahydroquinoline, benzomorpholine or indoline compound attached to the .dbd.CH-- group by an aromatic ring carbon atom in the position para to the aromatic amine nitrogen atom.
An electrophoretic migration image comprising an electrically photosensitive particulate material having the structure ##STR56## wherein R.sup.1 is hydrogen, lower alkyl, lower alkoxy, nitro, halogen, cyano, phenyl, lower alkylsulfonamido or lower alkoxycarbonyl and A.sup.1 is a monovalent and A.sup.2 is a divalent residue of an aniline, 1,2,3,4-tetrahydroquinoline, benzomorpholine or indoline compound attached to the .dbd.CH-- group by an aromatic ring carbon atom in the position para to the aromatic amine nitrogen atom.
