摘要： PURPOSE:To easily and surely determine whether or not the storage temperature of an article has risen above a predetermined temperature by bonding first and second labeling sheets together using a porous sheet, and containing a temperature controlling agent in one or more of the sheets. CONSTITUTION:A first labeling sheet has an adhesive layer which is provided on one side of a base sheet made preferably of a vinyl chloride resin and the like and which contains an organic chelate coupler. A second labeling sheet has an adhesive layer which is provided on one side of a base sheet and which contains a metallic compound that is colored when reacted with the organic chelate coupler, and both adhesive layers are bonded together by a porous sheet and at least one of the sheets contains a temperature controlling agent such as n-paraffin. As the temperature controlling agent flows within the porous sheet in a melting temperature range, either the metallic compound or the organic chelate coupler migrates within the porous sheet and is colored by reaction between them on contact. The color does not disappear even with the sheet kept below the melting point, and is detected to easily and surely determine whether or not the storage temperature of an article has risen above a predetermined temperature.

摘要： PROBLEM TO BE SOLVED: To obtain a new compound useful as a thermochromic material. SOLUTION: A compound containing repeating units of the formula: A1 -M1 -X- B-Y-M2 -A2 (A1 , A2 each are terminal chains; M1 , M2 each are mesogenic groups; X, Y each are binding groups consisting of COO, OCO; B is an aromatic group), e.g. 1,3-oxobis(hexyloxy-benzylidene anilinebenzoic acid)benzene. The compound is obtained by dissolving m-dihydroxybenzene, n-hexyloxyazomethinecaroboxylic acid, and dimethylaminopyridine in THF and subsequently reacting the components in the presence of dicyclohexylcarbodiimide. The new compound is a liquid crystal compound excellent in a thermal coloring or fading property without introducing an optically active group thereto. A thermochromic material using the new compound exhibits a ferrodielectric smectic liquid crystal phase structure or a ferrodielectric twisted grain powdery liquid crystal phase structure, and is suitable as a material for dimming elements, optical filters, recording elements, thermometric labels, heat-sensitive inks, heat-sensitive pigments, toner pigments, etc.

摘要： PURPOSE:To prevent nosocomial infection by forming a handrail or a handle of which a surface is covered with a resin layer containing biocidal material against methicillin resistant Staphylococcus aureus. CONSTITUTION:The surface of base material 2 forming a handrail, a handle, or the like is covered with a resin layer 1 containing MRSA biocidal material such as chitosan, ultrafin-grain zinc oxide or aluminosilicate solid grain. Since patients and the like are frequently in contact with this handrail or handle, the surface wears little by little, and the new face always comes out, so that there is no need to make the MRSA biocidal material percolate onto the resin surface. The MRSA attached by patients and the like can be thereby disinfected immediately so as to prevent infection to other patients.
