Abstract
An improved chalkboard marking surface comprises a rollable, flexible sheet of polypropylene having two sides that are opposite one another, each having a generally flat surface. On one side, a layer of adhesive is applied to the polypropylene substrate. On the same side of the polypropylene substrate, a selectively removable release sheet is preferably applied to the layer of adhesive for the purpose of keeping foreign materials from attaching to the adhesive when the chalkboard surface is not in use. On the reverse side of the polypropylene substrate, a layer of ink is applied which forms an abrasive surface after it dries, and importantly, results in a chalkboard surface that is lighter in weight.
