ABSTRACT:

BACKGROUND OF THE INVENTION
Conventional, decorative vinyl wall coverings are typically formed from a sheet of calendered polyvinyl chloride (PVC) resin formulation printed on its front face with fanciful designs and colors. A backing layer composed of a woven or non-woven sheet of polyester and/or cotton fibers may be bonded to the back face of the PVC sheet for dimensional stability, while a thin protective coating composed of an essentially transparent polymer can be bonded to the front face of the sheet.
The protective coatings currently used on commercially-available wall coverings adequately protect the underlying PVC sheet, including its fanciful design, from damage and abuse. Nonetheless, it is still difficult to remove certain types of markings from such products. For example, markings made from crayon, ink, paints and other materials often found in homes with children are often difficult to remove. That is why children in most homes are encouraged, in the strongest of terms, not to write on the walls.
SUMMARY OF THE INVENTION
Against this background, the present invention provides a new, decorative vinyl wall covering for use in decorating walls found in homes and other structures which is specifically designed to be writable and erasable.
This new, write-on/wipe-off wall covering takes the form of an elongated sheet composed of a continuous sheet of flexible plastic material having essentially the same size and shape as conventional vinyl wall coverings. The front face of this continuous sheet bears a decorative design of the same type as conventional wall coverings, and a protective covering is also applied to this front face to prevent it from being damaged or destroyed. However, in the case of the present invention, this protective coating is formed from a fluorocarbon polymer that is dry erasable—i.e., it can be easily erased with a suitable dry eraser when marked with a dry erasable ink.
With this structure, the inventive wall covering can be used in the same way as conventional wallpaper or other wall covering to provide a fanciful, decorative design covering some or all of the walls of a child's bedroom, for example. However, in this room, the child can be allowed or even encouraged to mark up the “covered” walls with his/her own designs, preferably using a dry erasable marker provided by his parents for this purpose, since these marks can be easily removed whenever desired. Similarly, the inventive wall covering can also be used by adults in a variety of different applications such as office areas, board rooms, conference rooms, near desks, in hallways or meeting areas, etc. Because the inventive wall covering is so easy to clean, individuals can “write on” its decorative design and then “wipe off” the notes/comments/drawings etc. so written without disturbing or destroying the design aesthetics of the wall covering itself.
