Abstract:
1. A method for forming an image, the method comprising the steps of: a) imaging an imageable precursor that comprises an overlayer over a substrate by imagewise applying an imaging solution to the overlayer and forming an imaged precursor comprising imaged and complementary unimaged regions in the overlayer; in which: the substrate has a hydrophilic surface; the overlayer is over the hydrophilic surface of the substrate; the overlayer comprises a water-solubilized phenolic resin; the water-solubilized phenolic resin comprises a water-insoluble novolac resin and a surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, and mixtures thereof; and the imaging solution comprises a water soluble insolubilizing agent; and b) developing the imaged precursor with an aqueous liquid and removing the unimaged regions, thus revealing the underlying hydrophilic surface of the substrate, without removing the imaged regions.
