Kind Code:
A1
Abstract:
A signboard buried in an indoor or outdoor wall face or a floor face in which the sign can be confirmed visually even if temperature rise is significant on the surface side. In an escape guiding signboard (1) where a light storage sheet (3) containing a light storage material exhibiting afterglow is provided on a substrate (2) and a protection board (4) having a sign section (5) formed on the inner surface is provided on the front side of the light storage sheet (3), the substrate (2) and the light storage sheet (3) are bonded to each other with a first adhesive layer (6) formed by fusing a first intermediate film while the protection board (4) and the light storage sheet (3) are bonded to each other with a second adhesive layer (7) formed by fusing a second intermediate film. Consequently, even when the temperature difference is large between the surface side and the rear surface side, the first adhesive layer (6) and the second adhesive layer (7) stretch and shrink to prevent cracking.
