摘要： PURPOSE:To provide a method of recording an image by widening a temperature range in which an image can remain stored and improving the handleability of the recording medium, by heating a liquid crystal element comprising a specific liquid crystal enclosed between upper and lower substrates, giving a corona discharge and locally heating with a laser beam to write image information therein. CONSTITUTION:A liquid crystal 2 which exhibits a thermooptical effect and comprising a trans-4-substituted cyclohexanecarboxylic acid trans-4'(trans-4''-alkylcyclohexyl) cyclohexyl ester of the formula (wherein R and R' are each a 1-10C alkyl; and n is 1 or 2) as main component is enclosed between upper and lower substrates 1, 3 to obtain a liquid crystal element 4. The element 4 is transferred in the direction as indicated with an arrow by means of a belt 20, heated to an isotropic liquid phase with a power source 10 and a heating lamp 5. An electric field is applied to the element 4 with a corona discharging device 6 to make the image disdplaying face transparent. Image information is recorded by locally heating and clouding the element 4 by irradiation with a laser beam which has been emitted from a semiconductor laser 7, passed through a polygon mirror 8 and condensed with an f-o lens 9, thereby to cause the heated area to be different in optical density from the non-heated area.

CONSTITUTION:A liquid crystal element formed by putting the following liquid crystal having a thermooptical effect between upper and lower substrates, a means for externally heating said liquid crystal element, a means for applying an electrical field to said element and a means for locally heating said element, are used. Said element is passed through these means in order, whereby the recording of image information is conducted. Said liquid crystal contains a 4'-alkyl-4-fluorobiphenyl of the formula (wherein R is a 1-10C alkyl) such as 4'-pentyl-4-fluorobiphenyl or 4'-propyl-4-fluorobiphenyl.

摘要： PURPOSE:To make possible the preservation and rewriting of an image by sandwiching a porous material which is formed into a sheet-like thin film with a pair of flexible substrates and packing the pores of the porous material with a liquid crystal material exhibiting a thermooptic effect. CONSTITUTION:A PET sheet having 50mum film thickness is used as the flexible substrates 1 and 2. A 'Teflon(R)' porous body having 40mum film thickness, 1mum average pore size and 75% voids is used for the porous material 3 of the thin film. The liquid crystal which exhibits a smectic A phase at an ordinary temp. is packed into the pores of the material 3 by which an image recording medium 4 is obtd. The thin film consisting of the porous material having prefer ably 20-100mum film thickness, 0.1-1mum average pore size and 50-75% voids is adequate. A liquid crystal mixture composed of a nematic liquid crystal and cholesteric liquid crystal or a smectic liquid crystal having a nematic phase, etc. are used as the liquid crystal. A large area ratio of the recording medium is thus easily obtd. and the flexible recording medium is made obtainable by the integral formation with the flexible substrates.

摘要： PURPOSE:To obtain a hologram recording medium with a sensitivity even to a semiconductor laser wavelength scope, and an excellent heat-proof and water proof property, by using a positive ion color-borate negative ion complex as a polymerization starting agent. CONSTITUTION:A hologram recording medium is formed by using a monomer to allow to polymerize, and a positive ion color-borate negative ion complex to allow to start polimerization, in a polymer. When the recording medium is exposed in a visual light, it shows sufficient sensitivity in the wavelength scope from the argon laser to the semiconductor laser according to the absorption of the polymerization starting agent. And by exposing an interference pattern by the interfering laser of two beams of an object beam and a reference beam with an adequate wavelength in this wavelength scope, the polymerization is promoted, and a reflection type or a permeation type of volume phase type hologram is formed. Consequently, a hologram with no color, a high transparency and heat-proof property, and a low water absorption coefficient can be obtained.
