  • Patent number: 10350927
    Abstract: Provided is a thermal transfer image-receiving sheet capable of suppressing the occurrence, inside a printer, of problems such as paper jam, printing failure, and abnormal sound. In a thermal transfer image-receiving sheet including a receiving layer on a substrate, the thermal transfer image-receiving sheet is provided with a perforation capable of being folded and torn off therealong; and the maximum resistance value is 0.5 N/cm or more and 1.0 N/cm or less as measured when the thermal transfer image-receiving sheet is folded along the perforation while one end side of the thermal transfer image-receiving sheet is being secured, and a predetermined force is being continuously applied to the other end side of the thermal transfer image-receiving sheet, the one end side and the other end side being situated across the perforation.

  • Publication number: 20170136797
    Abstract: A thermal transfer image-receiving sheet which does not cause printing failure while being provided with tear-off lines. The sheet includes a dye-receiving layer on one side of a backing sheet, a tear-off line provided crossing the sheet along a width direction of the sheet and roller contact areas configured to contact a transport roller of a printer provided on opposite sides in the width direction. In each of the roller contact areas on the opposite sides, the tear-off line is not parallel to the width direction of the thermal transfer image-receiving sheet in an area occupying half or more of the roller contact area in the width direction, and when that segment of the tear-off line which is not parallel to the width direction of the thermal transfer image-receiving sheet has one or more bends in the roller contact area, all the bends are bent at obtuse angles.

  • Publication number: 20150145939
    Abstract: The present invention is to provide a method for producing a print, which is able to prevent damages to the image-receiving sheet and generation of large wrinkles at the edges of the ink ribbon, to reduce printing unevenness, and thus to provide a high-quality print. Disclosed is a method for producing a print, in which a print is made on an image-receiving sheet by use of a specific thermal-transfer printer and an ink ribbon, wherein the ink ribbon has at least one color material layer and a protection layer; the image-receiving sheet has a receptor layer; and after printing all colors of the color material layers, the dynamic friction coefficient between the receptor layer surface of the image-receiving sheet before being coated with the protection layer and the outermost surface on the protection layer of the ink ribbon, is 0.4 or less.
