The present invention provides a retroreflective sheeting including a structured film having an array of structured elements and a sealing film attached to the structured film by a plurality of rivet-like connections perforating the sealing film. Preferably, the rivet-like connections form flanges. The preferred sealing film is a thermoplastic polymer with a ductile yield of at least about 20%. The retroreflective sheetings according to the present invention can also include a seal coat located on the sealing film. In some embodiments, the seal coat can be prepared from a seal coat precursor comprising radiation curable components. The present invention also includes methods of manufacturing the various embodiments of the retroreflective sheetings.

Structured retroreflective sheeting having a rivet-like connection

The present invention provides a retroreflective sheeting including a structured retroreflective film including an array of structured retroreflective elements, a thermoplastic sealing film located proximate the structured elements, and bonding agent between the sealing film and the structured retroreflective elements, wherein the bonding agent bonds the sealing film to the structured retroreflective film.

Bonded structured retroreflective sheeting

A retroreflective article comprising an ultra-flexible structured retroreflective sheeting having a front surface and a back surface, the sheeting retroreflecting light entering through the front surface, wherein the sheeting comprises an overlay film, a two-dimensional array of substantially independent structured elements, the structured elements bonded to the overlay film, and a sealing film forming the back surface of the sheeting and bonded to the overlay film between the structured elements; a plurality of indentations in the sealing film; and a seal coat located on the sealing film, wherein the seal coat at least partially fills the indentations in the sealing film.

Ultra-flexible retroreflective sheeting with coated back surface

The present invention provides a retroreflective sheeting having a front surface and a back surface, the retroreflective sheeting retroreflecting light entering through the front surface, wherein the retroreflective sheeting comprises encapsulated-lens retroreflectors. The retroreflective sheeting includes a plurality of indentations in the back surface of the retroreflective sheeting and seal coat at least partially filling the indentations.
