Abstract: PROBLEM TO BE SOLVED: To provide a reloadable color image recording medium by light of a short recording time and a color image recording method using the same. SOLUTION: This color image recording medium is formed by holding a compsn. obtd. by adding a 0.5 to 10 wt.% photochromic compd. to cholesteric liquid crystalline compds. having a mol.wt. of =35 deg.C between two sheets of substrates or films at least one of which are transparent or a mixture composed of these liquid crystalline compds. This color image forming method consists in subjecting the reloadable color image recording medium formed by holding the compsn. described above between two sheets of the substrates or films at least one of which are transparent to photoirradiation at a temp. at which the compsn. exhibits cholesteric liquid crystallinity or below, then rapidly cooling the recording medium down to a temp. below the glass transition tamp. at a rate of >=1 deg.C/sec.

Abstract: PROBLEM TO BE SOLVED: To obtain a new liquid crystalline compound consisting of a specific cholesterol derivative, capable of exhibiting red color hard to be developed with conventional thermal recording materials, and useful as an erasable full- color thermal recording material or the like. SOLUTION: This new liquid crystalline compound consisting of a new cholesterol derivative is shown by formula I [A is an 1,5-hexadienylene of formula II (R is H or methyl); Y is a cholesterol residue as a result of eliminating the hydroxyl group from cholesterol; (n) is 5-7], e.g. 8,12-eicosadienoic diacid dicholesteryl ester. This liquid crystalline compound is useful as e.g. a full-color thermal recording material freed from such a problem being hard to present red color as to be involved in conventional erasable full-color thermal recording materials. This compound of formula I is obtained by reaction of a dicarboxylic acid such as 8,12-eicosadienoic diacid with the corresponding cholesterol in the presence of dicyclohexylcarbodiimide and 4-dimethylaminopyridine.

Abstract: PROBLEM TO BE SOLVED: To obtain a new aromatic ester oligomer giving organic secondary nonlinear optical materials having good optical transparency and secondary nonlinear optical characteristics and not causing the deterioration of the characteristics with the passage of time. SOLUTION: A compound of formula I [R and R are each H or methyl; (n) and (n') are each 4-10; (m) is 2-5], for example, 4-[4'-(6-acryloyloxyhexyloxy) phenylcarbonyloxy]benzoic acid 6-acryloyloxyhexyl ester. The compound of formula I is preferably obtained by a method comprising converting an aromatic carboxylic acid of formula II [for example, 4-(6-acryloyloxyhexyloxy)benzoic acid] into the corresponding acid halide by the use of thionyl chloride, etc., and subsequently reacting the acid halide with a compound of formula III (for example, 4-hydroxybenzoic acid 6-acryloyloxyhexyl ester) in the presence of a hydrogen halide-capturing agent such as triethylamine in an organic solvent such as tetrahydrofuran.

Abstract: PROBLEM TO BE SOLVED: To obtain an org. polymer molding in which the refractive index can be reversibly changed with a large change width, and moreover, which can be easily formed, by using a material in which the refractive index is reversibly changed by irradiation of incoherent light and stopping the irradiation and controlling the change width of the refractive index to a specified value or larger. SOLUTION: The refractive index of the formed body is reversibly changed by irradiation of incoherent light or by stopping the irradiation, and further, the change width of the refractive index is >=0.005. From the viewpoints of easy production and a large change rate of the refractive index, the org. polymer which constitutes the formed body is preferably a linear or branched-chain org. polymer having polar org. groups on the side chains. Generally, the mol.wt. of the org. polymer ranges 1.000 to 500,000 of the weight average mol.wt., and preferably 5,000 to 300,000. Further, 2,6-diphenyl-4-(2,4,6-triphenylpyridinio)- phenolate is preferably added as an additive.

Abstract: PROBLEM TO BE SOLVED: To obtain gold with an adsorbed unimolecular layer of an organic thio group, useful as a nonlinear optical material by bringing the gold into contact with a specific solution in the presence of fluoride ion. SOLUTION: This gold with an adsorbed unimolecular layer of an organic thio group is the gold having the organic thio group of formula I or II [R , R , R and R are each an aryl or an (un)saturated aliphatic group] on the surface thereof adsorbed so as to form the unimolecular layer, and obtained by bringing the gold into contact with a solution containing tri(lower alkyl) silylethyl sulfide of formula III [R is an aryl or an (un)saturated apliphatic group] in the presence of fluoride ion. For example, a quarternary ammonium salt and hydrofluoric acid, especially tetrabutylammonium fluoride, are used as a fluoride ion source.

Abstract: PURPOSE:To produce the title crystal which has a high strength isotropically and a network structure having covalent bonds multi-dimensionally by subjecting crystals obtained from diacetylenedicarboxylic acid, a polyvalent metal carbonate and/or a polyvalent metal acetate to solid-state polymerization. CONSTITUTION:0.1-100mmol/l of a solution of a diacetylenedicarboxylic acid of the given formula (wherein n is 0-20) is added to a solution of a polyvalent metal carbonate and/or a polyvalent metal acetate (e.g., copper acetate) in a molar ratio of the acid to the metal salt of 1:(1-2) to form a homogeneous solution or suspension, which is stirred to react them at room temperature to 100 deg.C or below, thereby producing diacetylenedicarboxylic acid metal salt crystals. The crystals are irradiated with ultraviolet light for several to 100 hours, or with tens of MRad to hundreds of MRad or gamma ray (e.g., cobalt 60) in a vacuum, or are heated at tens of degrees to 200 deg.C for tens of hours to hundreds of hours, or are subjected to several thousands to ten thousands of atmospheres for tens of minutes, thereby effecting the solid-state polymerization.
