Laminates are disclosed having interlayers containing an infrared absorbing amount of lanthanum hexaboride (LaB 6 ) coated on or dispersed in a thermoplastic polymeric matrix. Preferably, the LaB 6 is combined with other materials, such as indium tin oxide, antimony tin oxide, organic dyes or pigments in a polymeric matrix of polyvinyl butyral (PVB). Alternatively, LaB 6 is coated on a sheet of polyethylene terephthalate and encapsulated with one or more sheets of PVB. The interlayers having LaB 6 dispersed therein or coated thereon are advantageously combined with encapsulation layers, reflective layers, dyed layers and/or pigmented layers. |
