Abstract

A dry erase member for receiving and releasably retaining a marking composition comprises a substrate coated with a layer of dry erase material on a first face thereof. In specific embodiments, the dry erase coating includes a major amount of a fluorinated polymer or a cellulose acetate based polymer, together with a minor amount of a melamine resin. The dry erase member may include a layer of adhesive on a second face of the substrate to allow for temporary or permanent mounting of the dry erase member onto a surface. In specific embodiments, the dry erase member is flexible. Also disclosed is a dust retaining strip for use with dry erase boards.
