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.
Claims20
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, said layer of adhesive being adapted to releasably secure said marking surface to a wall;
- and
- a layer of ink applied on said second side, said ink comprising varnish and forming a finish capable of accepting chalk marks.
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 adapted for selective repeated attachment of said marking surface to a vertical surface and for selective repeated detachment of said marking surface from said vertical surface without any substantial resulting damage to said vertical surface;
- and
- a layer of ink applied on said second side, said ink comprising a varnish and forming a finish capable of accepting chalk marks.
A chalk marking surface suitable for mounting on a substantially vertical surface comprising:
- a substrate having a first side and a second side, each of said first side and said second side being generally flat;
- a layer of adhesive applied on said first side and adopted for selective repeated attachment of said chalk marking surface to said vertical surface and for selective repeated detachment of said chalk marking surface from said vertical surface;
- and
- wherein said second side comprises at least one coating of ink comprising a varnish, and optionally, a dye or pigment, and forming a finish capable of accepting chalk.
