  • Laser-imageable flexographic printing precursors and methods of imaging
    Patent number: 9522523
    Abstract: A laser-engraveable composition comprises one or more elastomeric rubbers including at least 10 parts of one or more non-CLCB EPDM elastomeric rubbers, based on parts per hundred of the total weight of elastomeric rubbers (phr). The laser-engraveable composition further comprises 2-30 phr of a near-infrared radiation absorber and optionally 1-80 phr of an inorganic, non-infrared radiation absorber filler, as well as a vulcanizing composition that comprises a mixture of at least two peroxides. A first peroxide has a t90 value of 1-6 minutes as measured at 160° C., and a second peroxide has a t90 value of 8-40 minutes as measured at 160° C. This laser-engraveable composition can be used to form a laser-engraveable layer and to form various flexographic printing precursors.

  • 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.
