Abstract
Laser-engraveable flexographic printing plate precursors have a laser-engraveable elastomeric layer that comprises a non-free radical crosslinked polymeric binder, an infrared radiation absorbing compound, and a compound that remains stable in the precursor but upon imaging thermally degrades to produce gaseous products. The thermally degradable compounds can generate or liberate one or more gases such as nitrogen and carbon dioxide.
