| 摘要 |
Materials that undergo self-propagating exothermic solid-solid reaction upon ignition by a heating source (e.g., a laser) are used in the fabrication of recording constructions such as lithographic printing plates, photomasks and proofing sheets. A recording construction in accordance with the invention may include at least one ignition layer comprising at least two unreacted, solid chemical species which, upon exposure to heat, combine exothermically to form a final species that is physically disrupted; and a substrate thereunder that is substantially unconsumed by heat generated by the exothermic combination. To form a lithographic printing plate, the ignition layer (or its topmost component, or a surface layer thereover) and the substrate exhibit different affinities for ink and/or an abhesive fluid for ink.
