Abstract
A laminate comprises fused adherent layers of plastisol vinyl chloride polymer resins in which a first layer contains Sb.sub.2 O.sub.3 and a second layer contains TiO.sub.2. The flexible laminate is useful as a roofing membrane for the roof of a building wherein the layer containing the Sb.sub.2 O.sub.3 is adjacent a structural or insulation member of the roof of the building while the TiO.sub.2 layer can be exposed to the elements and can protect the Sb.sub.2 O.sub.3 layer from sunlight.
