Abstract
An adhesive article comprising a poly(meth)acrylate-based primer layer and methods of making same. The article can include a backing, a primer layer located on a first major surface of the backing, and a silicone-based adhesive located on the primer layer. The primer layer can be derived from a primer precursor comprising poly(meth)acrylate functionalities. The method can include applying a primer precursor onto a first major surface of a backing, the primer precursor comprising a compound comprising poly(meth)acrylate functionalities; irradiating the primer precursor; applying an adhesive on the irradiated primer precursor; and irradiating the adhesive and the irradiated primer precursor to form a primer layer located between the adhesive and the first major surface of the backing.
