摘要:
This invention pertains to an imageable article comprising a substrate having a surface, and an imageable film disposed upon said surface, said imageable film comprising a solvent soluble fluoropolymer having dichloroamino-functionalized perfluoroether pendant groups. When subject to imagewise exposure to UV radiation, the solvent soluble fluoropolymer will undergo crosslinking to an azo-crosslinked fluoropolymer having perfluoroether pendant groups. Under imagewise exposure, some portions of the imageable film undergo crosslinking while other portions do not. The portions that do not, can be washed away, leaving behind an image on the substrate, thereby preparing the imaged article hereof.
