Patent attributes
A magnetic erasable writable material for large format applications is disclosed, and includes a cast polyvinylchloride film with a mount surface opposite an etched receiver surface. Also incorporated is a transparent polyester film that has a marking side with a first predetermined hardness and an opposite seal side, laminated to the receiver surface. The marking side includes a clear superstrate that has a second predetermined hardness and applied to the marking side of the polyester film to lower its surface energy. The receiver surface is treated to have a surface energy adjusted to enable improved adherence of printed and preformed graphic elements, which are encapsulated when laminated between the PET film and receiver surface. The superstrate includes a perfluoropolyether, a polyurethane, an acrylated polyurethane, and/or an acrylate resin to harden the material.
