CONFORMABLE POLYMERIC MARKING SHEET Abstract of the disclosure Conformable marking sheet comprising a microporous thermoplastic polymer base sheet having a network of interconnected pores. The marking sheet has a low yield stress, making it conformable to rough surfaces. The pores of the base sheet can be filled with a diluent (wax) or they may have the diluent removed, for example by extraction. The construction may further comprise an adhesive on the bottom and a top marking indicium layer comprising a poly- meric binder in which is partially embedded a multiplicity of retroflective lens elements, e.g., transparent microspheres.
