Abstract:
1. A flexographic printing precursor comprising a thermally crosslinked laser-engraveable layer comprising a crosslinked elastomeric fluoropolymer and a fluoro-functionalized near-infrared radiation absorber, the crosslinked fluoropolymer having a glass transition temperature of less than and including 0° C., the crosslinked laser-engraveable layer being formed from a reactive fluoropolymer composition comprising a reactive fluoropolymer, the fluoro-functionalized near-infrared radiation absorber, and a compound that causes crosslinking of the reactive fluoropolymer during thermal curing, wherein the reactive fluoropolymer is selected from the group consisting of: poly(tetrafluoroethylene oxide-co-difluoromethylene oxide) α, ω-diol bis(2,3-dihydroxypropyl ether), poly(tetrafluoroethylene oxide-co-difluoromethylene oxide) α, ω-diol, ethoxylated poly(tetrafluoroethylene oxide-co-difluoromethylene oxide) α, ω-diol, and a multifunctional (meth)acrylate end-functionalized derivative of one of such compounds.
