Adhesive-backed chalkboard wall covering
View Patent ↗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.
1. A chalkboard suitable for repeated mounting on a vertical 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 to selectively attach said chalkboard to and detach said chalkboard from the vertical surface; and
a layer of ink applied on said second side, said layer of ink having a matte finish for accepting chalk.
2. The chalkboard of claim 1 , said substrate comprising polypropylene adapted to retain said ink.
3. The chalkboard of claim 1 , said substrate comprising vinyl adapted to retain said ink.
4. The chalkboard of claim 1 , further comprising a selectively removable liner applied on said adhesive layer for preventing foreign materials from attaching to said adhesive layer.
5. The chalkboard of claim 4 , said liner comprising a paper-based material.
6. The chalkboard of claim 4 , said liner comprising silicone.
7. The chalkboard of claim 1 , said layer of ink consisting of a single layer of matte varnish mixed with a colored dye.
8. The chalkboard of claim 7 , said layer of matte varnish being UV Stampable Matte Varnish.
9. The chalkboard of claim 7 , said colored dye comprising Sinvacure UV IMP #50 Black.
10. The chalkboard of claim 1 , said layer of ink comprising UV Stampable Matte Varnish and Sinvacure UV IMP #50 Black in a ratio of about 4:1, respectively.
11. 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, said layer of adhesive being adapted to releasable secure said marking surface to a vertical wall; and
a layer of ink applied on said second side, said ink comprising a pigment and forming an abrasive matte finish for retaining chalk markings on said surface.
12. The surface of claim 11 , said section of polypropylene being rollable and flexible.
13. The surface of claim 11 , further comprising a release sheet disposed on said layer of adhesive, said release sheet being selectively removable from and re-attachable to said layer of adhesive.
14. The surface of claim 11 , said ink comprising UV Stampable Matte Varnish and Sinvacure UV IMP #50 Black.
15. The surface of claim 14 , said UV Stampable Matte Varnish and Sinvacure UV IMP #50 Black being combined in a ratio of about 4:1, respectively.
