Abstract: PURPOSE:To improve definition and exposing rate by exposing the recording material with visible rays and laser beam, and forming surface relief images by the heating alone without using a developer after exposing. CONSTITUTION:The relief images are formed only by the heating treatment after exposing. A high-pressure mercury lamp, ultra-high pressure mercury lamp, high-pressure xenon lamp, halogen lamp, etc., are usable as a light source. After the recording body is exposed for a prescribed period of time by using such light sources, the recording body is heated in a dark place at 60 to 150 deg.C, more preferably 80 to 120 deg.C heating temp. The heating time is 1 to 20 minutes, more preferably 2 to 10 minutes. The exposing time necessary for the image formation is shortened if the heating is executed in the state saturated with steam. The exposing rate and definition are improved in this way.

Abstract: PURPOSE:To obviate the degradation of definition occurring in flowability with lapse of time by providing a liquid crystal layer contg. a dichromatic dye via a molecular layer of a compd. which is reversibly changed in structure by light on a transparent substrate. CONSTITUTION:This recording element has the structure in which a liquid crystal layer 3 is sandwiched between two sheets of the substrates 1 having the monomolecular layers 2 of a photochromic compd. The photochromic compd. causes a change in the structure when a part A thereof is irradiated by light and, therefore, the perpendicular arrangement of this part is broken and the liquid crystal attains the arrangement in parallel with the surface. The anisotropy of the dichromatic dye changes accordingly. Although the part B which is not irradiated by the light is pale in color, the part A irradiated by the light is changed to a dark color and, therefore, the reading of the light information by the transmittance of the light of the wavelength absorbed by the dye is executed. Since the light of the wavelength which does not generate photochromism by selection of the dye, the breakage of the information is obviated. The degradation of the definition by the liquid crystal having flowability with time is thereby obviated.

Abstract: PURPOSE:To increase the optical response speed and to improve the repeating reproducibility and the shelf stability of a record by dispersing a clathrate compound consisting of a specified anthracene deriv. and gamma-cyclodextrin in a resin binder. CONSTITUTION:An anthracene deriv. represented by the formula (where R is a hydrophilic substituent) and gamma-cyclodextrin are dissolved in an aqueous medium to form a clathrate compound, and light is irradiated to dimerize the anthracene deriv. in the clathrate compound. A resin binder is dissolved in the soln. and formed into a film, and the dimer of the anthracene deriv. in the clathrate compound dispersed in the resin film is depolymerized by irradiating light on the resin film or heating the film. Thus,a reversible org. optical memory material showing photochromism by a reversible photodimerization reaction in the resin binder is obtd. The optical memory material has a satisfactory optical response property and superior reversibility in the writing of information and gives a record with superior shelf stability and processability. It is used as an optical information storing or recording material.
