PURPOSE: To increase the density of a transferred image and to eliminate or reduce the nonuniformity in the density of a transferred dye image of a transparency by a method wherein a second dye image having the same hue as a first dye image and being transferred at the same position is transferred onto a dye acceptor element by heating another portion of a dye donor element or another dye donor element further in the shape of the image at one or more times. CONSTITUTION: This method comprises a process wherein a dye donor element constituted of a support having a dye layer on the surface is heated in the shape of an image and thereby a dye image is transferred onto a dye acceptor element constituted of a transparent support having a dye image accepting layer on the surface so that an image of specified density be formed and wherein the density of the image obtained by thermal transfer of dye is increased. The process is repeated twice or more so as to increase the density to a desired level. In a preferable embodiment, accordingly, a dye donating layer different from the first one is heated in the shape of the image and further a third image using the same dye and being identical with the two images is transferred onto the same place so that an image of increased density be formed. In the case of obtaining a transparency, the dye is made uniform and a place wherein the density is nonuniform is eliminated by conducting printing in a plurality of times. |
