Abstract
Processing tapes for use in preparing optical articles include a thermally stable tape backing and a low tack adhesive layer at least partially coated on tape backing. The low tack adhesive layer includes a crosslinked, polyester-containing (meth)acrylate-based polymer that is essentially free of volatile components, is unchanged after heat aging of 150 C for 1 hour under a pressure of 4.31 kiloPascals, and is able to removably adhere to the anti-reflective, nanostructured surface coating of an optical construction.
