  • Publication number: 20020174790
    Abstract: The present invention provides a method for image formation, that can yield thermally transferred images which are excellent in various fastness properties even under severe service conditions, and an intermediate transfer recording medium for use in the method for image formation. The method for image formation comprises the steps of: providing an intermediate transfer recording medium comprising a substrate film and a transfer portion provided separably on the substrate film; forming an image on the intermediate transfer recording medium in its transfer portion; transferring the transfer portion onto an object; and, thereafter, again transferring the intermediate transfer recording medium in its next transfer portion once or more onto the object with the image formed thereon. In this case, in the intermediate transfer recording medium, a hologram image is set every at least second image plane, and an image can be formed on the transfer portion having the hologram image.
