    摘要: A composite structure includes a first layer, a support layer, and a urethane acrylate layer disposed between the first layer and the support layer. The first layer is a show surface of the composite structure. The urethane acrylate layer includes a urethane acrylate composition that includes a urethane acrylate adduct. The urethane acrylate adduct is the reaction product of an isocyanate component and a stoichiometric excess of a functionalized acrylate component. The isocyanate component has at least two isocyanate groups. The functionalized acrylate component has at least one isocyanate-reactive functional group that is reactive with at least one of the isocyanate groups for forming the urethane acrylate adduct. The resulting urethane acrylate composition is sufficiently low in viscosity for many processing applications, and the urethane acrylate layer including the urethane acrylate composition exhibits sufficient adhesion to the first layer and support layer.
