摘要 |
As a writing surface, the invention provides a waterproof solid sheet that has been formed from a polyvinyl chloride and that has at least one writing face that receives controllably semi-permanent ink writing. The writing is only controllably removable from the writing face by a remover-solvent; upon removal of the writing, the writing face is left writing-free and residue-free. The writing surface otherwise resists adverse conditions.
