摘要： A lithographic printing plate is comprised of an anodized aluminum support having thereon an oleophilic image-forming layer comprising an infrared-absorbing agent dispersed in a film-forming cyanoacrylate polymer binder. The plate is imagewise exposed to a focused high-intensity infrared laser beam which removes the oleophilic image-forming layer by thermal ablation to thereby reveal the underlying hydrophilic support surface. The cyanoacrylate polymers provide superior performance due to their combination of low decomposition temperature, good ink receptivity, good adhesion to the support and good wear characteristics.
