A ferroelectric liquid crystal element comprises a ferroelectric liquid crystal and a pair of substantially parallel substrates having opposite surfaces between which the ferroelectric liquid crystal is sealed. The substrates are provided with electrodes to which voltages are applied, and are subjected to one axis orientation treatment so as to orient the ferroelectric liquid crystal. The ferroelectric liquid crystal has an orientation state represented by the following condition: &thgr; &thgr;a>{fraction (&thgr;/2)}.

To suppress curling phenomenon of a recording medium to which a liquid composition is applied while securing ejection stability. A liquid composition for used in an image recording method including the steps of applying an ink containing a colorant in a dissolved state or a dispersed state to a recording medium and applying to the recording medium a liquid composition which destabilizes the dissolved state or the dispersed state of the colorant in the ink by coming into contact with the ink, the liquid composition including at least a polyvalent metal ion, water, and water-soluble organic compounds 1 and 2, in which a content X (mass %) of the water-soluble organic compound 1 in the liquid composition is 15 mass % or more, and the content X (mass %) of the water-soluble organic compound 1 in the liquid composition and a content Y (mass %) of the water-soluble organic compound 2 in the liquid composition satisfy a specific relationship.
摘要:
The present invention provides an anti-curl agent containing an amide compound of specific structure and molecular weight, an ink jet ink containing the amide compound, a method for ink jet recording to form images by ejecting the ink, and a method for reducing curl of recording media using the ink. The anti-curl agent of the present invention can reduce shape changes of a printed paper with a lapse of time, i.e., the curl phenomenon, tending to occur in particular with a plain paper printed over the entire surface, without deteriorating image quality.
摘要:
A recording medium comprises a porous outermost layer on a substrate, the porous outermost layer containing a particulate thermoplastic resin, and the particulate thermoplastic resin exhibiting a &Dgr;E value of not higher than 20 after light exposure. The difference of glass transition temperature of the particulate thermoplastic resin from minimum film-forming temperature thereof may be not less than 10° C., and the minimum film-forming temperature is not lower than 50° C. A process for producing the recording medium comprises forming a porous outermost layer by heat treatment at a temperature of not lower than the glass transition temperature of the particulate thermoplastic resin, but not higher than the minimum film-forming temperature thereof.
