Abstract:
1. A method for forming an image, the method comprising the steps of: a) imaging an imageable element with ultraviolet radiation, the imageable element comprising an imageable layer over a support, and forming an imaged imageable element comprising imaged and complementary unimaged regions in the imageable layer; and b) developing the imaged imageable element with a developer and removing the unimaged regions without removing the imaged regions; in which: the imageable layer comprises an acid generator, a crosslinking agent, and a binder; the acid generator is an iodonium, sulfonium, or diazonium salt in which the anion is an organic sulfate anion or an organic thiosulfate anion; the crosslinking agent comprise at least two acid-activatable reactive groups; the binder comprises a polymer that contains a reactive pendent group capable of undergoing acid-catalyzed crosslinking with the crosslinking agent, in which the reactive pendent group is selected from the group consisting of hydroxyl, carboxylic acid, sulfonamide, alkoxymethyl, and mixtures thereof; the imageable layer additionally comprises a colorant; about 20 mJ/cm the developer is a solvent based developer.
