Abstract: The object of the present invention is to provide a resin composition that contains a near-infrared absorbent in which heat-induced discoloration is suppressed, and the resin composition is a resin composition made from a near-infrared absorbent, an antioxidant, and a resin, wherein the near-infrared absorbent is a particulate made from copper phosphonate represented by Formula (1) (wherein, R1 is a group represented by —CH2CH2-R11, and R11 indicates a hydrogen atom, an alkyl group, or an alkyl fluoride group)), and the antioxidant is at least one type selected from hindered phenol-based antioxidants and phosphorous-based antioxidants having not less than one structure represented by Formula (2) (wherein, R2 to R4 indicate alkyl groups and R5 to R8 indicate hydrogen atoms or alkyl groups.) bonded to a phosphorous atom in the molecule, and not having a structure represented by Formula (3) (wherein, R indicates an alkyl group.) bonded to the phosphorous atom in the molecule.

Abstract: Disclosed is a benzonitrile derivative which is useful as a production intermediate for benzylamine derivative represented by the general formula (5) below and s secondary amine derivative represented by the general formula (9) below. Also disclosed are a method for producing such a benzonitrile derivative and a use thereof as a bactericide. Specifically disclosed are a novel benzonitrile derivative represented by the general formula (1) below, a salt thereof, a production method thereof, and a use thereof as a pharmaceutical intermediate or a bactericide. [Chemical formula 1] (5) (In the formula, n represents an integer of 0-3, and R1 represents a hydrogen, a linear or branched alkyl group having 1-6 carbon atoms or the like.) [Chemical formula 2] (9) (In the formula, n and R1 are a defined above, and R4 represents a hydrogen, a linear or branched alkl group having 1-6 carbon atoms or the like.

Abstract: A hard disk device includes a magnetic disk for storing data, a temperature sensor for detecting an ambient temperature and a controller for controlling operation of the hard disk device. The magnetic disk has a first memory region where data are memorized with a high density when the ambient temperature is higher than a predetermined temperature and a second memory region where data are memorized with a low density when the ambient temperature is lower than the predetermined temperature. The data stored in the second memory region can be transferred to the first memory region when the ambient temperature becomes higher than the predetermined temperature. It is assured that the data are successfully stored in the hard disk device at any temperature without much sacrificing the memory capacity.
