Abstract
A laser-engraveable composition comprises one or more elastomeric rubbers and 2-30 phr of a near-infrared radiation absorber, such as carbon black and optionally 1-80 phr of an inorganic non-infrared radiation absorber filler. 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.
