    摘要： The present disclosure is a thermal transfer sheet including a substrate and a transfer layer, the transfer layer containing a luster pigment, wherein, when an image of the thermal transfer sheet is taken from a side on which the transfer layer is present using an optical microscope at a 500-fold magnification in order to obtain an image, the image is analyzed with image analysis software, dark and light portions of the analyzed image are inverted, automatic thresholding is then performed by an ISODATA method in order to determine a threshold value of a brightness distribution of the analyzed image, binary representation is subsequently performed such that portions in which brightness is less than the threshold value are colored in black and portions in which brightness is equal to or more than the threshold value are colored in white, and the number and the total area of the black portions and the total area of the white portions are calculated, the ratio of the total area of the black portions to the total area of the white portions is 0.03 or more and 0.5 or less, and the black portions have an average area of 100 µm 2 or more and 300 µm 2 or less.

    摘要： A thermal transfer printer includes a first supply unit configured to supply an intermediate transfer medium in which, on one of surfaces of a first base, a transfer layer including a receiving layer is disposed, a second supply unit configured to supply a thermal transfer sheet in which, on one of surfaces of a second base, a colorant layer and a particle layer are disposed, a printing unit configured to heat the thermal transfer sheet, to transfer a colorant from the colorant layer to the receiving layer to form an image, and to transfer the particle layer onto the receiving layer, a third supply unit configured to supply a transfer-receiving body, and a transfer unit configured to place the intermediate transfer medium and the transfer-receiving body on top of each other such that the transfer-receiving body faces the particle layer on the receiving layer, and to heat the intermediate transfer medium to transfer the transfer layer onto the transfer-receiving body such that the particle layer is placed in at least a portion of a peripheral area of the transfer-receiving body, to produce a printed product.
