Laser printable dry-erase substrates and methods of their manufacture and use

Abstract

Laser printable, dry-erase substrates, along with their methods of formation and use, are provided. The laser printable, dry-erase substrate can include a base sheet defining a surface and a dry-erase coating on the surface of the base sheet. The dry-erase coating comprises a film-forming polymeric material (e.g., a polyacryl, a polymethacryl, a polyurethane-polyacryl mixture, a polyurethane-polymethacryl mixture, an urethane-acryl copolymer, or a mixture thereof) and a wetting agent (e.g., a nonionic surfactant that has a polyethylene oxide chain and an aromatic hydrocarbon lipophilic or hydrophobic group). The film-forming polymeric material melts and flows at a laser printing temperature so as to bond to toner ink.
