Abstract
A laser-ablatable element for direct laser engraving has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. This relief-forming layer includes a laser-ablatable polymeric binder and an infrared radiation absorbing compound that is present at a concentration profile such that its concentration is greater near the bottom surface than the image-forming surface. This arrangement of the infrared radiation absorbing compound provides improved ablation efficiency, particularly when laser exposure is carried out adiabatically.
