Title: Delamination-resistant cellular retroreflective sheeting
Inventor: BERGESON DAVID L
IPC: B32B7/02
Filed: 1986-04-30
Granted: 1994-06-25
Abstract: An improved, delamination-resistant, cellular retroreflective sheeting comprising: 1) base sheet having a layer of retroreflective elements disposed over one of its surfaces, 2) a polymeric cover film disposed in spaced relation from the layer of retroreflective elements, and 3) a network of narrow intersecting bonds extending between said cover film and base sheet to adhere the cover film and base sheet together and form a plurality of cells within which retroreflective elements are hermetically sealed. The cover film, which comprises a continuous polymeric phase and a discontinuous polymeric phase, is biaxially oriented such that the discontinuous polymeric phase is in the form of minute disks distributed substantially uniformly througout the film. The retroreflective sheeting is resistant to delamination because under the influence of forces that tend to remove the cover film from the base sheet, the cover film is generally removed only at the edge of the sheeting, e.g., from the front row of cells, but no further. Most of the sheeting remains intact and ready for continued utility.
