    Abstract: The present invention provides a photosensitive lithographic printing plate which displays superior ink receptivity and superior film strength of the photosensitive layer (image area). The photosensitive lithographic printing plate is produced by providing, on top of a support, a photosensitive composition comprising a fluororesin having a fluoro aliphatic group of 3 to 20 carbon atoms in which at least two of three terminal hydrogen atoms are substituted for fluorine atoms, and an ethylene based unsaturated group, as well as a negative photosensitive compound.

    Abstract: The present invention includes a method of preparing an inkjet ink imaged lithographic printing plate, comprising the steps of: imagewise applying onto a substrate coated with an inkjet ink reactive coating composition comprising a diazonium material, an inkjet ink to produce an imaged coated substrate wherein the inkjet ink imaged regions are oleophilic and more developer-insoluble than non-imaged regions; and contacting said imaged and non-imaged regions of said an imaged coated substrate and an aqueous developer to selectively remove said coating from said developer soluble non-imaged regions. The present invention also includes a lithographic printing plate, such as an inkjet ink imaged lithographic printing plate, which is prepared by the method of the present invention.

    Abstract: The present invention includes an imageable element, which can be: (a) an imageable element comprising an imaging layer which comprises: an aromatic diazonium salt containing compound having an alkoxy substituent and an aromatic diazonium salt containing compound free of an alkoxy substituent; a polyvinyl acetal binder; and a sheet substrate; or (b) an imageable element comprising an imaging layer which comprises: an aromatic diazonium salt containing compound having an alkoxy substituent and an aromatic diazonium salt containing compound free of an alkoxy substituent; and a sheet substrate. The imaging layer includes a total aromatic diazonium salt containing compound content of at least 10 weight percent. The molar ratio of the aromatic diazonium salt containing compound having an alkoxy substituent to the aromatic diazonium salt containing compound that is free of an alkoxy substituent is from about 1.0:1 to 70:1. Upon imagewise exposure and development, an imaged element is obtained, which is mounted on a dry printing press containing lithographic ink and used to produce printed stock.
