Abstract
Patterned articles can be prepared by applying a release polymer to a substrate in a desired pattern, applying a substrate-adherent polymer over the pattern and substrate, and mechanically removing the substrate-adherent polymer from the pattern without requiring solvent. Suitable mechanical removal methods include applying adhesive tape to the substrate-adherent polymer and peeling the tape and substrate-adherent polymer away from the pattern, and abrading the substrate-adherent polymer from the pattern using impact media.
