Abstract:
A fire resistant layered reflecting and photoluminous material consisting essentially of:a first layer of prismatic light reflective material having an underlying surface formed with a plurality of minute prism-shaped formations projecting therefrom and an overlying substantially smooth light transmissive surface, said first layer having a first peripheral edge;a second layer comprising a homogeneously blended mixture of a resin, an effective amount of a fire retardant additive and an effective amount of a photoluminescent material, said second layer having a second peripheral edge; anda third layer comprising a fire retardant fabric material, said third layer having a third peripheral edge;wherein said first, second and third layers are in overlying relationship, are proximately disposed, and are joined together into a unitary composite structure along a border of finite width extending continuously along said first, second and third peripheral edges, said prism-shaped formations coextensive with said border and defining a central region whereat said first layer, said second layer and said third layer are physically distinct; said central region, having a layered reflecting and photoluminous material, simultaneously radiating phosphorescent light from said second layer through said underlying surface of prism-shaped formations and through said smooth light transmissive surface and reflected light from said prism-shaped formations through said smooth light transmissive surface of said first layer; and only phosphorescent light radiating from said border.
