    摘要： An electrochromic device includes: a first insulating substrate; a first conducting layer disposed over the first insulating substrate; an electrochromic layer disposed over the first conducting layer, wherein the electrochromic layer comprises an electrochromic polymer having a polymer backbone comprising one or more meta-conjugated linkers (MCLs) and one or more aromatic moieties (Ars), wherein each of the one or more MCLs is partially conjugated with one of the one or more Ars at a meta position of the one or more MCLs; an electrolyte layer disposed over the electrochromic layer; a second conducting layer disposed over the electrolyte layer; and a second insulating substrate disposed over the second conducting layer. A thickness of the electrochromic layer is from 10 nm to 1500 nm resulting in transmittance of 85%-99.9% at a wavelength of 550 nm at a neutral state of the electrochromic layer.

    摘要： [Problems] An object of the present invention is to provide: thermochromic color-memory composition which effectively expresses a property of being capable of interchangeably memorizing and retaining colors and is thus applicable to various fields; and thermochromic color-memory microcapsule pigment encapsulating the same. [Means for Solution] Provided are thermochromic color-memory composition and thermochromic color-memory microcapsule pigment encapsulating the same, the thermochromic color-memory composition including: (a) a component composed of an electron-donating color-developing organic compound; (b) a component composed of an electron-accepting compound; and (c) a component composed of an ester compound represented by the following Formula (1) as a reaction medium which controls color reaction between the components (a) and (b): (wherein, R represents an alkyl group having 3 to 18 carbon atoms or an aliphatic acyl group having 3 to 18 carbon atoms; X represents a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, an alkoxy group having 1 or 2 carbon atoms or a halogen atom; Y represents a hydrogen atom or a methyl group; and Z represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 or 2 carbon atoms or a halogen atom).
