An image display medium that includes a photoconductive layer containing a photochromic compound and an electron accepting compound; and a substrate, in which the photochromic compound contains a fulgide compound, and the electron accepting compound contains a compound selected at least from: a) a phosphonic acid compound having an aliphatic group containing 12 or more carbon atoms; b) an aliphatic carboxylic acid compound having an aliphatic group containing 12 or more carbon atoms; and c) a phenolic compound having an aliphatic group containing 12 or more carbon atoms, a process for forming an image using the medium, and a multicolor image-forming apparatus using the medium and suitable for the process.

Liquid crystalline amides: linear arrangement of rod-like molecules by lateral intermolecular hydrogen bonding and molecular shape effect
Bent- and straight-rod shaped liquid crystalline amides 1–3 were designed and synthesized, and their thermodynamic behaviors were investigated by polarized optical microscopy and differential scanning calorimetry, and their layer distances were measured by X-ray diffraction. Weak or strong hydrogen bonds were observed in variable-temperature FT-IR spectra for bent-rod shaped compounds 1 possessing a long alkoxy chain (OR2), straight-rod shaped compounds 2, and straight-rod shaped 3 in their smectic C, smectic Cx, and smectic A phases, respectively. Thus, these liquid crystalline amides could generate linear molecular aggregates in their smectic layers by the lateral intermolecular hydrogen bonds.
