  • Protective coating for imaging elements
    Patent number: 5667935
    Abstract: An element comprising, in order: (a) a removable substrate; (b) a transparent, nonphotosensitive, polymeric layer having a thickness of less than about 0.002 cm and a gloss of 45-70; said polymeric layer consisting essentially of at least one thermoplastic polymer having an elongation at break of greater than 30%, a glass transition temperature of 35.degree.-70.degree. C.; and (c) an elastomeric layer and optionally an additional, different removable substrate (d) adjacent to the elastomeric layer, wherein the polymeric layer exhibits improved adhesion to the removable substrate (a) when removable substrate (d) is removed is described.
    Type: Grant
    Filed: May 4, 1995
    Date of Patent: September 16, 1997
