摘要： A photosensitive lithographic form plate that can be directly prepared by using digital signals from a computer or the like by using an infrared laser or the like (i.e., a photosensitive lithographic form plate that can be directly prepared), through using an image-forming material that can be directly inscribed with heat generated by irradiation of a laser light and is suitable for use in a lithographic form plate. The image-forming material used in the present invention comprises an infrared light absorbing agent having a hydrophobic group which changes to hydrophilic due to heat. The image-forming material may further contain a macromolecular binder insoluble in water and soluble in an aqueous solution of an alkali, or a macromolecular binder that is decomposed by heat or with an acid and becomes soluble in water or an alkali. In an exposed portion of the photosensitive layer, the infrared light absorbing agent is decomposed due to heat by irradiation of infrared light, and an acid is generated.
