    Abstract: A hot-stamping foil has a carrier that is a base film or a coated base film, and a laminated optical decoration formed on the carrier in a removable manner. The laminated optical decoration includes a laminated optical structure, an anchor layer formed on the laminated optical structure at a side opposite against the carrier, the anchor layer being a mixture of an acid-modified polyolefin and a vinyl chloride-vinyl acetate copolymer, and an adhesive layer which is formed on the anchor layer at a side opposite against the laminated optical structure. The adhesive layer has an adhesive domain containing an acid-modified polyolefin as a major component, and a non-adhesive domain containing a blocking preventing agent as a major component. The blocking preventing agent is one or both of a resin filler and an inorganic filler. A glass transition point of the blocking preventing agent is greater than 60 °C.

    Abstract: Provided is a thermal transfer recording medium that has high dye transfer sensitivity and that is resistant to the occurrence of dye precipitation and scumming (i.e., having good storage stability). The thermal transfer recording medium (1) according to an embodiment of the present invention comprises a heat-resistant lubricating layer (40) laminated on a first surface of a substrate (10), and an undercoat layer (20) and a dye layer (30) laminated in this order on a second surface of the substrate. The dye layer (30) contains, as binders, a polyvinyl acetal resin, a phenoxy resin, and a graft copolymer having a main chain comprising polycarbonate and a side chain comprising a vinyl-based polymer, and also contains compounds I, II, and III as cyan dyes.

    Abstract: There is provided an optical structure having a structure surface which includes a plurality of display region groups including a first display region group and a second display region group. In each display region of each display region group, an azimuth angle is formed between a projection direction and a reference direction on the structure surface, and a plurality of reflective surfaces belonging to the display region produce an image. In each display region group, a plurality of display regions include a set of display regions whose azimuth angles are different from each other, and the plurality of display regions display an image unique to the display region group in a display direction by a plurality of reflective surfaces belonging to each of the display regions. The display direction of the first display region group is different from the display direction of the second display group to provide brightness that is different between the image unique to the first display region group and the image unique to the second display region group, in the respective display directions of the images.
