Abstract
Laminates are disclosed having interlayers containing an infrared absorbing amount of lanthanum hexaboride (LaB6) coated on or dispersed in a thermoplastic polymeric matrix. Preferably, the LaB6 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, LaB6 is coated on a sheet of polyethylene terephthalate and encapsulated with one or more sheets of PVB. The interlayers having LaB6 dispersed therein or coated thereon are advantageously combined with encapsulation layers, reflective layers, dyed layers and/or pigmented layers.
