摘要： A chiral smectic main chain-type polymer liquid crystal includes mesogen units and a flexible chain group connecting the mesogen units having a length equal to or longer than 1,4-butylene group. The polymer liquid crystal is also characterized by having at least two units having mutually different optically active groups and having at least two recurring units which show mutually reverse helical rotations in its chiral smectic phase. Because of these features, the polymer liquid crystal can show an improved responsiveness because of its chiral smectic ferroelectricity based on an elongated helical pitch while retaining a good film-formability of a main chain-type polymer liquid crystal.

摘要： An image forming medium is constituted by a laminate including at least an optical scattering layer and a backing member preferably comprising a pattened color filter. The laminate is composed to have an interface between the optical scattering layer and the backing member capable of reflecting light incident to the optical scattering layer. The optical scattering layer may comprise a polymer liquid crystal optionally containing a fluorescent agent or nucleating agent so as to enhance the optical scattering effect. The interface may be given by a low-refractive index layer, such as air layer. The optical scattering layer and the backing member can be separated and combined with an adjusting means for adjusting the relative position of the optical scattering layer and the backing member to provide an image forming apparatus.

摘要： Disclosed herein is an image-forming method, including performing image formation on the basis of pixel data by using at least a yellow recording agent, a magenta recording agent, and a third recording agent. A color represented on a recording medium by the third recording agent on a color space of CIE-L*a*b* has lightness higher than lightness of a color reproduction region represented on the recording medium by a combination of the yellow recording agent and the magenta recording agent, and has a hue angle in the color reproduction region. A difference in hue angle on the color space between a color represented by the yellow recording agent and a color represented by the magenta recording agent is in a range of 60 to 113°.
