PHOTOCHEMICAL AND PHOTOTHERMAL REARRANGEMENTS FOR OPTICAL DATA AND IMAGE RECORDING

摘要

Systems and method for optically recording data. One optical recording medium (100) comprises a substrate (120) and a markable coating (130) on the substrate, the markable coating (130) including a leuco dye and developer precursor. The developer precursor comprises a compound that undergoes photochemical or thermal rearrangement in response to a stimulus so as to become a developer for the leuco dye.
