    Abstract: A method for making a reusable printing plate in which a hydrophobic image area is formed on a hydrophilic plate surface containing a photocatalyst. The method includes the steps of carrying out a hydrophobic agent application process in which a solution containing an organic compound having a property of reacting with the plate surface by a heating process and a property of being decomposed by the action of the photocatalyst when irradiated by light having a higher energy than a band gap energy of the photocatalyst is applied on the plate surface; carrying out an image area formation process in which a part of the plate surface is subjected to a heating process to form a hydrophobic image area; and carrying out a non-image area formation process in which the organic compound applied to an area other than the hydrophobic image area on the plate surface is removed.

    Abstract: 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.
