Abstract
Release sheets that can be used to manufacture artificial leather, paneling, and other products, as well as methods of making such release sheets are described. In general, the release sheets include a substrate and a release coating. The release coating is formed on the substrate by applying a crosslinkable material, such as an acrylic functional material, then crosslinking the material. An example of a release coating is the crosslinked reaction product of an acrylic functional material and a Michael donor. The release sheets have surfaces that can be replicated with high fidelity using a casting material, such as a urethane casting material.
