Patent number: 9346239Abstract: A method is used to provide a pattern of a functional material for example on a receiving element. To provide this pattern, a laser-engraveable patternable element is imagewise exposed with laser-engraving radiation. This element has a laser-engraveable layer comprising a thermoplastic elastomeric interpolymer alloy. This interpolymer alloy comprises a non-crosslinked halogenated polymer, a partially crosslinked polyolefin, and a polyester. A laser-engraved patterned element is formed that has a relief image in the laser-engraveable layer, and this relief image can be contacted with a suitable functional material that is then transferred to the receiving element to provide the desired pattern.Type: GrantFiled: September 26, 2012Date of Patent: May 24, 2016Assignee: EASTMAN KODAK COMPANYInventors: Lawrence A.

Patent number: 8501388Abstract: 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.Type: GrantFiled: December 22, 2011Date of Patent: August 6, 2013Assignee: Eastman Kodak CompanyInventors: Christine J. Landry-Coltrain, Mitchell S. Burberry, Dennis R. Perchak, Kam C. Ng, Lee W. Tutt, Lawrence A. Rowley, Linda M. Franklin
