Laser-engraveable compositions and flexographic printing precursors

摘要

Flexographic printing precursors are prepared using laser-engraveable compositions containing a laser-engraveable resin and chemically-crosslinked organic porous particles. The presence of these porous particles, which can include an infrared radiation absorber, improves various imaging and performance properties in the preparation of flexographic printing members such as flexographic printing plates and printing sleeves.
