Abstract (en)
Electrically photosensitive particles for electrophoretic migration imaging processes. Electrically photosensitive particles (4) for use in electrophoretic migration imaging processes comprise a compound having the structure: <CHEM> wherein m and n are zero, one or two; R<1> and R<2> each represents hydrogen, alkyl or aryl; Y represents O or S; L<1> through L<5> represent hydrogen, alkyl or aryl, or in addition, either L<1> and L<2> or any two of L<3>, L<4> and L<5> together represent the atoms needed to complete a carbocyclic ring; A<1> represents a basic heterocyclic nucleus and A<2> represents the A<1> nuclei, an aryl group or a heterocyclic nucleus. The particles (4) can be used in an electrophoretic migration imaging process which consists in placing them between two electrodes (1) and (5) and submitting them to an activating radiation and an electric field for obtaining an image on electrodes (1) and (5).
