Abstract
Abstract A method of making an array of a repeating mosaic pattern of colorants carried on a support using (a) a plurality of donor materials each comprising a radiation-absorbing material and, respectively, a sublimable dye of a different color, and (b) a receiver element comprising a support having thereon a dye-receiving layer, wherein each donor material is in turn brought into face-to-face contact with the receiver and exposed patternwise to a high-intensity light source to transfer the desired pattern of dye to the receiver layer.
