Abstract:
A thermal recording material of the invention contains, as a storability improver, tris(2-methyl-4-hydroxy-5-t-butylphenyl)butane trapping and containing water and/or methanol and having a crystal structure that shows a maximum X-ray diffraction peak at a diffi-action angle 2¸ of 6.58° according to X-ray diffraction measurement using an X ray having a wavelength of a Cu-K± line. The recording material has improved heat resistance in non-printing sections while maintaining the moisture-and-heat resistance in printing sections. The thermal recording material of the invention has a thermal-recording layer that contains the tris(2-methyl-4-hydroxy-5-t-butylphenyl)butane in an amount of preferably 0.1 to 15% by mass with respect to the thermal-recording layer. The amount of the water and/or methanol trapped and contained in the tris(2-methyl-4-hydroxy-5-t-butylphenyl)butane is preferably 0.1 to 10% by mass in total.
Abstract:
PROBLEM TO BE SOLVED: To provide a decomposition accelerator of volatile organic halogen compound by microorganisms which provides nutrition elements such as nitrogen, phosphorus, potassium, sulfur and so on for a long time which is necessary for proliferation and growth of microorganisms as well as hydrogen necessary for reductive dehalogenation, and which accelerates the proliferation and growth of microorganisms; and a decomposition acceleration method using the same. SOLUTION: The decomposition accelerator of volatile organic halogen compound by microorganisms which includes condensation reaction products of an amino acid and an oxycarboxylic acid, or an ester of this condensation reaction products and polyalcohol as active ingredients; and also the decomposition acceleration method using the same are provided.

Abstract:
PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material such as heat-sensitive recording paper which has a color development reinforcing effect of a printing part, while possessing heat and humidity resistance of a printing part, and besides, an improved heat resistance of a non-printing part. SOLUTION: This heat-sensitive recording material contains a tris (2-methyl-4-hydroxy-5-t-butyl phenyl) butene, including water and/or methanol, as a keeping quality modifier. The above butene has a crystal structure showing a maximum diffraction X-ray peak at a diffraction angle 2θ=6.58° by diffraction X-ray measurement using X rays with a wavelength of Cu-Kα.
