Abstract: In accordance with the invention, there are provided methods for affixing a transparent coating upon a substrate, such as canvas, paper, cardboard or the like, that optionally has an image printed or otherwise recorded thereon, the coating effective to repel water and to prevent smearing or running of inks that are not water-fast, such as, for example, water-based inks used in ink-jet printers. In accordance with the invention, a coating composition including a particulate thermoplastic resin a plasticizer and, optionally, one or more of a wetting agent, a light stabilizer, an ultraviolet light absorber and a flatting agent is applied on the substrate and heated to cure the composition to a transparent, flexible, water-impervious coating.
