摘要： There is disclosed an oxygen absorption composition without requiring moisture in oxygen absorption which comprises an oxygen absorbent comprising, as a principal component, an oligomer in liquid form having an unsaturated group, a number-average molecular weight in the range of 150 to 4,000 and a viscosity in the range of 100 to 4,000 cP such as butadiene oligomer in liquid form and an oxygen absorption-accelerating substance, being supported on a carrier; and an other gas absorbent. The above principal component may be replaced with an oligomer in liquid form having an unsaturated group and being incorporated with an oxygen-unabsorptive diluent to adjust the viscosity of the mixture to 10 to 4,000 cP. The above composition is enhanced in oxygen absorption capability in every preservation atmosphere from a low humidity to an intermediate and high humidity, easily producible, minimized in gas generation after oxygen absorption and almost free from odor problem.

摘要： A vacuum heat insulator (10) comprising an oxygen absorbent (18) which does not require water to absorb oxygen, a dehydrating agent and an acidic gas absorbent. In a preferred embodiment, the oxygen absorbent (18) comprises (i) at least one of an unsaturated fatty acid compound and a chain hydrocarbon polymer having an unsaturated group as a main component, and (ii) an oxygen absorbent accelerator. When arranged in a vacuum container or vacuum package (12), the vacuum heat insulator (10) absorbs oxygen, water and acidic gases which permeate the vacuum container or package (12) or which are generated within the vacuum container or package (12), to thereby maintain the degree of vacuum and good thermal insulating properties.

摘要： PROBLEM TO BE SOLVED: To stably manufacture a deoxidizing agent-packaging bag with a humidity indicator by attaching a humidity indicator label to a surface of the deoxidizing agent packaging bag to easily judge the humidity in a sealed container and specifying the tensile strength of the humidity indicator label and a peelable paper. SOLUTION: Since a metal and an electronic material are corroded with oxygen and water, they are sealed and preserved by sealing a humidity indicator together with a deoxidizing agent and a dehumidifying agent. A humidity indicator label is attached to the surface to form a deoxidizing agent packaging bag and the humidity is easily judged. The tensile strength of the humidity indicator label is set to be not less than 1 kgf with the width of 15 mm, and the tensile strength of a peelable paper is set to be not less than 1 kgf with the width of 15 mm, respectively. The humidity indicator label is a pressure sensitive adhesive label to adhere the adhesive agent by applying the pressure, and a substance to be discolored by absorbing the humidity is impregnated and coated on a base material on which the adhesive agent is coated, and the peelable paper is attached thereto.

摘要： PROBLEM TO BE SOLVED: To improve oxygen absorption rate and to stabilize oxygen absorption performance by dissolving a metallic soap in a specific quantity of oleic acid or ricinoleic acid, adding a liquid hydrocarbon oligomer having an unsaturated group to form a uniform solution and carrying the same on a carrier to sufficiently dissolve the metallic soap. SOLUTION: The quantity of oleic acid and ricinoleic acid is in a range of 0.05-30 pts.wt., preferably about 0.1-25 pts.wt. and further preferably about 0.15-20 pts.wt. per 100 pts.wt. in total of the liquid hydrocarbon oligomer having the unsaturated group and oleic acid or ricinoleic acid. And the quantity of the metal in the metallic soap of a catalyst is in a range of about 0.001-2 pts.wt., preferably about 0.005-1 pts.wt. and further preferably about 0.01-0.5 pts.wt. per 100 pts.wt. in total of the liquid hydrocarbon oligomer having the unsaturated group and oleic acid or ricinoleic acid. Where, as the metallic soap, a naphthenic acid metal salt, an octylic acid metal salt or the like is suitably used.

摘要： PROBLEM TO BE SOLVED: To effectively effect insecticide of a cultural asset with a deoxidant while eliminating the discoloration/fading of the cultural asset with aldehyde by enclosing the deoxidant and an aldehyde absorbent not to impede the oxygen absorption reaction and not to absorb water in a container of gas barrier property together with the cultural asset. SOLUTION: When a variety of cultural assets consisting of various kinds of materials are preserved, an aldehyde absorbent and a deoxidant, and a carbon dioxide absorbent as necessary, are stored and sealed in a container of gas barrier property together with the cultural assets. The aldehyde absorbent is formed by carrying at least one kind of amine, thiol and sulfonic acid in a porous substance, and these substances are preferably a solid in a temperature range of 10-50 deg.C. The carbon dioxide absorbent is at least one kind of sodium hydroxide, potassium hydroxide or magnesium hydroxide or the like, and a pigment is prevented from being discolored by absorbing carbon dioxide generated from the deoxidant and the cultural assets.

摘要： PURPOSE: To simply suppress the weathering, oxidation and deterioration of an excavation by encapsulating the excavation in a gas barrier type container together with an oxygen absorbing agent. CONSTITUTION: As a gas barrier type container, e.g. a plastic container or container made of a gas barrier type material such as a film bag, etc., is selected depending on the purpose. Then, as an oxygen absorbing agent, an oxygen absorbing agent which can absorb oxygen under a dry condition by jointly applying a desicant is desirable, and especially an oxygen absorbing agent containing an oxygen absorption-promoting substance, and of which the major component is a chain hydrocarbon copolymer containing an unsaturated fatty acid compound and/or unsaturated group is preferably applied. Then, the preservation atmosphere for excavation is made a state wherein oxygen is substantially removed, preferably, oxygen and moisture are substantially removed, and the excavation is encapsulated together with the oxygen absorbing agent and desicant. By this method, the oxidation and deterioration of excavation can be prevented from happening, and the archaeological value of the excavation can be maintained without losing the configuration and color tone at the time of an excavation.
