Abstract
Temporary graphic films that may be applied to rough, outdoor surfaces such as concrete or asphalt pavement are provided. The temporary graphic films are durable, yet easily removed and may include a fracturable material that permits fluid flow to reduce slip and fall situations.
Claims9
A temporary graphic film assembly, comprising:
- a printable polymeric layer comprising a printed image or graphic and having a first surface and a second surface and having a thickness of less than 3 mils, wherein the printable polymeric layer comprises a polymeric coating composition comprising a blend of fracturable material configured to fracture over contours in an irregular surface, wherein the blend includes a ratio of cellulose acetate butyrate and sucrose acetate isobutyrate within the range of about 7:1 to about 3:1, wherein the polymeric coating composition does not contain any acrylic polymers;
- a reflective layer disposed beneath the printable layer;
- a layer of pressure sensitive adhesive having a first and second surface, the first surface of the adhesive layer adhered to the reflective layer;
- wherein the graphic film assembly is conformable to surfaces having a roughness average Ra of at least 25 microns, and
- wherein the pressure sensitive adhesive layer includes an acrylic emulsion adhesive.
