Abstract: PURPOSE:To enhance the light resistance of the recording material and to stabilize both a decoloring state and a color developing state over a long period of time by using prescribed spirooxazines and a bivalent metal ion supplying material in combination. CONSTITUTION:This recording material is constituted by dispersing the spirooxazines (A) and the bivalent metal ion supplying material (B) into a thermoplastic resin film in such a manner that the components A, B form a colored chelate by the effect of heat and are dissociated to the decolored state by visible light. The compd. of formula is usable as the component A. In the formula, R1 denotes lower alkoxyl, lower alkyl, etc.; R2 denotes alkyl or benzyl; R3 denotes lower alkoxyl, hydroxyl group, etc. The complex ion compds. of Ni (II), Cu (II), etc., are usable as the component B.

Abstract: PURPOSE:To obtain a liquid crystal material which is homogeneously oriented in a prescribed direction by laminating a chemical material layer having the property to orient to the angle intrinsic to an oscillation direction of light and a liquid crystal layer on a substrate and irradiating the layers with linearly polarized light for a specified period of time. CONSTITUTION:The liquid crystal material formed by laminating the chemical material layer 2 having the property to orient to the angle intrinsic to the oscillation direction of light and the liquid crystal layer 3 on the substrate 1 is irradiated with the linearly polarized light for the specified period of time. At least either of two sheets of the substrates 1, 4 of the sandwich type liquid crystal cell which can be homogeneously oriented may be a transparent substrate and the other may be formed of a sheet consisting of metals, such as copper, iron, aluminum, and platinum or the sheet coated with these metals. A photochromic compd. is most ordinarily used as the compd. having the property to be oriented by the linearly polarized light on at least one substrate. The liquid crystal material homogeneously oriented to the prescribed angle is obtd. in this way.

Abstract: PURPOSE:To obtain the title material improved both in durability in the repeated developing and extinguishing of a color and in the persistence of the stability in both bleached and colored states by dispersing a specified spirooxazine and a donor of divalent metallic ions in a medium. CONSTITUTION:The title material is obtained by dispersing a donor (A) of divalent metallic ions, preferably comprising a metal (II) complex ion compound prepared by chelating at least one kind of ligand with a metal (II) ion compound [e.g. a complex ion compound comprising a mixture of Ni(ClO4)2 acetylacetonate and N,N'-tetramethylenediamine], and a spirooxazine (B) of the formula (wherein R is a substituent capable of coordinating with metal, such as OH, lower alkoxyl, alkyl ketone or aryl ketone; the C at the 5-position may have a substituent, such as lower alkoxy, lower alkyl, halogen or amino; the N at the 1-position may have a substituent, such as long-chain alkyl, aryl or benzyl; and the naphthalene ring may be a quinoline ring) which reversibly forms a chelate with component A by the action of light in a medium (C) preferably comprising a thermoplastic resin.

Abstract: PURPOSE:To obtain an excellent intraocular lens by crosslinking a specific high-molecular compound by irradiating the same with light. CONSTITUTION:A polyvinyl alcohol derivative being a specific high-molecular compound is constituted by introducing a constitutional unit represented by formula I into the main chain of polyvinyl alcohol and obtained, for example, by the reaction of polyvinyl alcohol with a styrylpyridinium salt or styrylquinolium salt having an acetal or formyl group. The content of the constitutional unit represented by the formula I is pref. 0.3-20mol.% of polyvinyl alcohol. As a pref. method for forming an intraocular lens using this material, there is a method wherein said material is injected in a crystal capsule as an aqueous solution to be crosslinked.

Abstract: PURPOSE:To enable rapid recording, reading out and erasing by light and to enable the long-period preservation of recording by using a film having a composite laminar structure of the clay and bilayer obtd. by the ion complex of a surfactant and clay compd. which are respectively specific. CONSTITUTION:The film having the composite laminar structure of the bilayer- clay film obtd. from the ion complex of the cationic surfactant having 2 straight chain higher alkyl groups and the anionic laminar clay compd. is used. Spirobenzopyranes are dispersed as a photochromic compd. into this film. A change is generated in the physical state of a film-like binder by a stimulus except light, for example, heat or the like so as to arbitrarily control the state in which the photochromic reaction progresses and the state reverse therefrom. The recording, reading out and erasing by the light are thereby rapidly enabled and the long-period preservation of the recording is enabled.
