PROBLEM TO BE SOLVED: To provide a light-reflecting display sign having a property of preventing posters, exhibiting a beautiful appearance effect and giving visibility of light for a wide incident angle.SOLUTION: A light-reflecting display sign comprises a light-reflecting composite coating film on a surface of a power pole, the light-reflecting composite coating film including at least a retroreflective film containing retroreflective particles and an adhesive resin and a protective film covering the retroreflective film. The protective film contains paraffin wax (A) and modified silicone (B). Particularly, visibility of the retroreflective film is further enhanced even at night by forming a portion where the retroreflective film is formed and a portion where a base coating material containing a black pigment is exposed, into stripes to give a similar appearance as a conventional power pole signboard. As the display sign has poor adhesiveness to the surface thereof, sticking of posters can be prevented. As the display sign is formed of only a coating material and has no projection that is present on the conventional power pole signboard, safety for a pedestrian can be increased. |
