Abstract: A thermoplastic resin includes 22% to 49% by mole of a constituent unit (A) derived from a diol represented by the following general formula (1A), 40% to 75% by mole of a constituent unit (B) derived from a diol represented by the following general formula (2A), and 0% to 15% by mole of a constituent unit (C) derived from a diol represented by the following general formula (3A), with respect to the total amount (100% by mole) of the constituent units in the resin:

Abstract: A packaging body for a light control sheet including a light control sheet, and a packaging member that supports the light control sheet. The light control sheet includes a first transparent electrode film, a second transparent electrode film, a sealing section that seals a gap between the first transparent electrode film and the second transparent electrode film in an outer peripheral section of the light control sheet, and a liquid crystal composition that is enclosed in the gap surrounded by the sealing section. The packaging body includes an easy-peel tape that covers the sealing section and fixes the sealing section to the packaging member. This allows the packaging body for the light control sheet to protect the quality of the light control sheet.

Abstract: A light control sheet includes electrode layers including first transparent electrode layer and a second transparent electrode layer, a light control layer formed between the first and second transparent electrode layers, and transparent support layers including a first transparent support layer and a second transparent support layer such that the first transparent support layer is formed on the first transparent electrode layer on the opposite side of the light control layer and has a support surface supporting the first transparent electrode layer and that the second transparent support layer is formed the second transparent electrode layer on the opposite side of the light control layer. The first transparent electrode layer has one or more grooves extending along the support surface such that the first transparent electrode layer has an electrode element having a narrow portion formed between portions of the groove and having a width of 1 mm or more.

Abstract: This invention relates to an ink ribbon, a cartridge containing the ink ribbon and a method of discriminating a failure location from an ink ribbon base film when the failure occurs on the ink ribbon. The ink ribbon is a sublimation-type ink ribbon manufactured from a column of the plural columns into which the ink ribbon base film is cut. The ink ribbon has a recording portion for recording column information indicating a column out of the plural columns of the ink ribbon base film, from which the ink ribbon is manufactured. The cartridge contains the ink ribbon. When a failure occurs on the ink ribbon, the column including the failure is discriminated from the plural columns of the ink ribbon base film based upon the recorded column information of the ink ribbon.
