A method of making a laser ablated article includes forming an article of one or more layers, each of which absorbs radiation within the wavelength range of from about 210 nm to about 360 nm and at least one of which is a hydrophobic fluorine-containing graft copolymer derived from at least one fluorine-containing monomer and at least one comonomer containing at least one aromatic group, and processing the article with a laser that outputs radiation at a wavelength of between about 210 nm and about 360 nm. The graft copolymer is surprisingly absorptive to radiation within the specified wavelength range. Articles formed using laser ablation include a nozzle plate of an ink jet printhead, wherein the nozzle plate contains ink jet openings formed by laser ablation and has a polymer substrate coated with the laser ablatable hydrophobic fluorine-containing graft copolymer.</PTEXT>
