ABSTRACT:
A method for forming an image on a dye. The dye absorbing visible light of a first wavelength, but not visible light of a second wavelength. The dye is decolorized when visible light of the first and second wavelength irradiate the dye simultaneously. Decolorization will be effected only if visible light of the first wavelength and visible light of the second wavelength are simultaneously applied. The method utilizes lasers as the source of the visible light of the first and second wavelengths; thus insuring formation of high resolution images.
