Title:
PHOTOSENSITIVE AZO COMPOUND AND IMAGE FORMING DEVICE UTILIZING THE SAME
Document Type and Number:
WIPO Patent Application WO/1992/006074
Kind Code:
A1
Abstract:
A photosensitive azo compound represented by general formula (I), wherein R?1¿ and R?2¿ may be the same or different from each other and each represents halogen, halogenated C¿1? to C¿6? alkyl, -NO¿2?, -SC=N, -C=N, -SO¿3?H, -C¿n?F¿2n?COOF, -C¿n?F¿2n?COF, -C¿n?F¿2n?COOC¿m?F¿2m+1?, wherein n and m each represents an integer of 1 to 6, -SO¿2?NH¿2?, -SO¿2?NHCF¿3? or -SO¿2?NHCH¿3?; and R?3¿ represents hydrogen, -NH¿2?, -NHCOCH=CH¿2? or a group containing vinyl or vinylene in its structure. The compound reversibly isomerizes upon being irradiated with light to thereby cause a change in wettability. An image forming device wherein a photosensitive medium containing this compound is selectively exposed and ink is selectively adhered to the surface of this medium to form an image, which is transferred and fixed.
