Abstract
A composition comprises a fluoropolymer such as an elastomeric fluoropolymer and at least 1 weight % of a fluoro-functionalized near-infrared radiation absorber. This composition can be formed into laser-engraveable layers for various elements that can be laser-engraved to provide relief images. The resulting laser-engraved elements can take various forms including flexographic printing members, and can be used to apply various inks to receiver materials in an imagewise fashion.
