  • Conforming a microporous sheet to a solid surface
    Patent number: 5411351
    Abstract: 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 polymeric binder in which is partially embedded a multiplicity of retroflective lens elements, e.g., transparent microspheres.
    Type: Grant
    Filed: June 5, 1992
    Date of Patent: May 2, 1995
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: James E. Lasch, James M. Kaczmarczik, James A. Klein, James M. Jonza
