Abstract
Abstract A dye-donor element for laser-induced thermal dye transfer comprising a support having thereon a dye layer and an infrared-absorbing material, characterized in that the dye layer has a layer coated thereover which contains spacer beads of such particle size and concentration that effective contact between the dye-donor element and a dye-receiving element is prevented during the laser-induced thermal dye transfer.
