Abstract
A laser-engraveable flexographic printing precursor or patternable element comprises a laser-engraveable layer having two orthogonal dimensions. This laser-engraveable layer comprises one or more elastomeric resins and non-metallic fibers that are oriented in the laser-engraveable layer predominantly in one of its two orthogonal dimensions. The non-metallic fibers have an average length of at least 0.1 mm and an average diameter of at least 1 μm. The oriented non-metallic fibers reduce curl and shrinkage in the precursor and improve print quality and press life.
