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.

A marking surface comprising:
- a rollable, flexible substrate having a first side and a second side, each of said first side and said second side having a generally flat surface;
- a layer of adhesive applied on said first side;
- and
- a layer of ink applied on said second side, said ink comprising a first ink comprising a pigment or dye and a second ink comprising a matte varnish, where the first and second ink are printed from independent sources onto the same second side so as to form a single layer of ink capable of accepting chalk when said layer of ink is dried.
A marking surface comprising:
- a section of polypropylene having a first side and a second side, each of said first side and said second side having a generally flat surface;
- a layer of adhesive applied on said first side;
- and
- a layer of ink applied on said second side, said ink forming an abrasive matte finish when said ink is dried for removing and retaining chalk markings on said surface.
