ABSTRACT:
A reflex-reflecting sheeting of a type having on the surface of the sheeting many isolated small compartments which are respectively hermetically sealed in the form of cells is characterized in the structure in which a support film comprises an upper layer which is in contact with glass beads and a lower layer disposed on the opposite side and having larger cohesive force and rubbery elasticity than the upper layer, and a protective film made of a substantially unoriented resin. The sheeting thus constructed exhibits strong resistance against separation of the protective film and the support film even under high temperature and humidity.
