ABSTRACT:
A retroreflective marking material which can be secured to a substrate, e.g., a firefighter's helmet, and then readily removed when desired, even after exposure to heat and flame. The material comprises a retroreflective layer made up of a layer of retroreflective elements in a binder layer, a fire resistant fabric, and a defined fire resistant adhesive on the rear of the fire resistant fabric. The adhesive adheres strongly to polycarbonate and can be stripped from polycarbonate after being held in a forced air oven at 260.degree. C. for 5 minutes. The marking material can contain fluorescent coloring agent(s) to afford good daylight visibility.
