20110089609 | LASER-ABLATABLE ELEMENTS AND METHODS OF USE - 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.

20120094018 | METHOD OF MAKING LASER-ABLATABLE ELEMENTS - A method is used to make a laser-ablatable element for direct laser engraving that has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. The relief-forming layer can be prepared by applying multiple formulations. Each formulation comprises a coating solvent, a laser-ablatable polymeric binder, and an infrared radiation absorbing compound. The infrared radiation absorbing compound concentration in the resulting sub-layers is different in each adjacent pair of sub-layers so that the concentration is always greater in each pair sub-layer that is closer to the substrate, and the concentration is progressively greater in the sub-layers as they are closer to the substrate after the coating solvent is removed, wherein the multiple sub-layers provide a relief-forming layer so that the sub-layer farthest from the substrate provides a relief-image forming surface. | 04-19-2012 |
