Abstract
Retroreflective sheeting ( ) comprises a reflective base ( ), a transparent film layer ( ) which is colored different from the color of reflected light of the reflective base ( ) and a pressure-sensitive adhesive layer ( ). The transparent film layer ( ) is removably provided on the reflective base ( ) via the pressure-sensitive adhesive layer ( ). Part ( ′) of the transparent film layer ( ) is to be cut out on use so that the transparent film layer ( ) may form a desired image. The peel strength between the transparent film layer ( ) and the reflective base ( ) is 25 to 400 gf/25 mm. After the transparent film layer ( ) is pressed to the reflective base ( ) under a pressure of 5 kgf/cm , the peel strength between the transparent film layer ( ) and the reflective base ( ) is 700 gf/25 mm or greater.
