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 tvalue of 1-6 minutes as measured at 160° C., and a second peroxide has a tvalue 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.
