ABSTRACT:
A flexible retroreflective sheet material is formed by adhering a first face of a first flexible synthetic resin sheet material to a synthetic resin second sheet material by a first adhesive which preferentially adheres to the second sheet material. On the second face of said first sheet material are thereafter formed closely spaced retroreflective microprisms having a height of 0.001-0.010 inches. A second adhesive is applied to the second face of said first sheet and firmly engages therewith. A flexible backing material is adhered to the second adhesive over the second face. Lastly, the second sheet material and first adhesive are stripped from the first sheet material to produce a firmly bonded flexible composite sheet material comprised of the adhesively bonded first sheet material and backing material. The retroreflective microprisms may be coated with a reflective metal deposit or surrounded by air to provide a retroreflective interface.
