  • Patent number: 7060336
    Abstract: An image receiver material which, even when wound on a roll of a smaller diameter in a printer, an image receiver sheet is not peeled, such that the image receiver material is not susceptible to running troubles in a printer. To this end, there is provided a seal type image receiver material in which the image receiver material includes a separator including a release sheet base material and a release agent layer provided on its one surface and an image receiver sheet including a receiver sheet base material and an adhesive layer provided on its one surface.
