A retroreflective film ( 30 ) comprising a cover layer ( 40 ), a prismatic layer ( 42 ), a reflective layer ( 44 ), an adhesive layer ( 46 ), and a protective liner ( 48 ). The prismatic layer ( 42 ) has retroreflective prism elements ( 60 ) formed on its rear surface and the reflective layer ( 44 ) covers the rear surfaces of the prism elements. The film ( 30 ) has an elongation of at least 20% and can be constructed for use with a substrate subjected to a cold-work deformation process, such as stamping, embossing, or pressing.
