    摘要: A method for preparing a waterless lithographic plate is disclosed. A mixture that contains a water-repellant release material and a compound that becomes aqueous developable on heating is coated on a support, heated imagewise, and developed to produce the printing plate. Preferred water-repellant release materials are acrylic and methacrylic polymers with fluorinated side chains and silicone containing polymers, especially organo functional siloxanes. Preferred compounds that become aqueous developable on heating are phenolic resins as well as complexes of phenolic resins with quinolinium compounds, benzothiazolium compounds, pyridinium compounds, and imidazoline compounds.

    摘要: There is described a method of preparing a water-less lithographic plate by coating a positive working photosensitive composition onto an oleophilic base imagewise exposing the plate and developing it to remove the areas of the photosensitive composition which have been light exposed, coating overall the surface of the plate with a layer of a composition which is ink-releasing or when cured becomes ink releasing, then either as a separate step or as a combined step curing the ink-releasing composition or drying the ink-releasing composition and light exposing overall the plate, then redeveloping the plate to remove the photosensitive composition remaining after the first development and any ink-releasing composition overlying the photosensitive composition.

    摘要: There is described a method of preparing water-less lithographic plate which comprises imagewise exposing a lithographic plate coated with a photosensitive composition, processing the exposed plate in an aqueous based developing liquid to remove those areas of the photosensitive composition which are removable by the developing liquid, drying the plate and coating the plate with an ink releasing coating composition which adheres to those areas of the plate from which the photosensitive composition has been removed, but which does not adhere to those areas of the plate from which the photosensitive composition which has not been removed, further treating the plate to cure or fix the ink-releasing composition thus providing ink-receptive areas of the plate which are those areas of the plate from which the photosensitive composition which has not been removed in the developing liquid and ink-releasing areas of the plate which are covered with the cured ink-releasing composition. Both positive working and negative working lithographic plates can be used in this method to produce positive working water-less plates and negative working water-less plates.

    摘要: A method of preparing a printing form precursor for printing, or a printed circuit board precursor or a semiconductor precursor, the method comprising the step of applying electromagnetic radiation having a pulse duration of not greater than 1×10−6 seconds, in an imagewise manner, to an imagable surface of the precursor. The imaging process may cause ablation of the coating of the precursor or permit its development in a developer. In each case the imaging radiation needs not be tuned to imaging chemistry (if any) present in the coating. Alternatively the imaging process may induce a change of hydrophilicity or hydrophobicity, or other change of state, of an uncoated substrate.

    摘要: A printing form precursor comprises a printing surface which comprises an inorganic metal compound, the printing surface being hydrophobic and capable of being made hydrophilic by energy but capable of becoming hydrophobic again, for reuse, if desired. An associated method of printing includes steps of subjecting the printing surface imagewise to energy so as to locally increase its hydrophilicity sufficient to make the surface differentiated in its acceptance of an oxophilic a printing ink; applying the ink to the printing surface and printing from the printing surface; causing or allowing the printing surface to undergo a reduction in hydrophilicity sufficient again to make the printing surface uniform in its acceptance of a printing ink; and,if wished, repeating these steps on multiple occasions. Thus the invention achieves the goal of providing a printing form precursor which does not need a chemical developer, and which can be used multiple times, to print different images.
