  • Dual-layer laser-imageable flexographic printing precursors
    Patent number: 9266316
    Abstract: A flexographic printing precursor can be imaged and used for flexographic printing. This precursor has at least two laser-engraveable layers, in which the underlying non-printing laser-engraveable layer is more sensitive than the outermost non-metallic printing laser-engraveable layer. The non-printing layer-engraveable layer comprises (1) a first elastomer, (2) a polymer that is nitrocellulose, a polymer comprising a triazene group, a glycidyl azide polymer, or a poly(vinyl nitrate), and (3) a first near-infrared radiation absorber. The outermost non-metallic printing laser-engraveable layer comprises a second elastomer and a second infrared radiation absorber.

  • LASER-IMAGEABLE FLEXOGRAPHIC PRINTING PRECURSORS AND METHODS OF IMAGING
    Publication number: 20130101834
    Abstract: A laser-engraveable composition comprises one or more elastomeric rubbers and specific amounts of inorganic, non-infrared radiation absorber fillers, a vulcanizing composition, carbon nanotubes, and other near-infrared radiation absorbers such as non-conductive carbon blacks, within certain weight ratios. This laser-engraveable composition can be used to form various flexographic printing precursors that can be laser-engraved to provide relief images in flexographic printing plates, printing cylinders, or printing sleeves.
