摘要:
A liquid crystal composition is principally constituted by at least a liquid crystal and a gel-forming compound which forms a gel with the liquid crystal. The gel-forming compound has a discotic liquid crystal phase and assumes a supermolecular structure when it is mixed with the liquid crystal. The supermolecular structure may preferably have at least one intermolecular interacting side having at least one —CONH— group allowing multi-dimensional intermolecular interaction.

摘要:
An image forming process provides an excellent ink fixation effect for high speed, low energy consumption printing. Two-valued or multi-valued gradation expression of a picture element, or the smallest output unit, is realized by controlling the number of liquid droplets impacting on a recording medium for each dot formed on the recording medium. The liquid droplets are subjected to physical or chemical modification so as to be fixed to the recording medium. The present invention is also directed to an image forming apparatus, an ink for liquid droplet recording and a liquid droplet ejection and projection method that can use the image forming process.
摘要:
A liquid crystal device is constituted by a pair of substrates each provided with an axis for aligning liquid crystal molecules in a uniaxial aligning direction, and a liquid crystal composition disposed between the pair of substrates and comprising at least a liquid crystal and an aligned gel-forming compound forming a gel with the liquid crystal. The gel-forming compound is aligned in a direction substantially parallel or perpendicular to the uniaxial aligning direction.
