An interlayer comprised of a thermoplastic resin and at least one special effect metal pigment. The use of a thermoplastic resin and at least one special effect metal pigment provides a special effect metal appearance without sacrificing other characteristics of the interlayer, and wherein the color of the interlayer measured in reflectance mode is different from the color measured in transmission mode.

Polymer interlayers comprising special effect metal pigments

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

Infrared absorbing compositions and laminates

Plasticized polyvinyl butyral sheet containing dispersed therein, an infrared-absorbing effective amount of at least one quaterrylenetetracarboxylic diimide infrared-absorbing additive of formula I in the specification. A glass laminate having visible light transmitting and infrared light absorbing properties contains such sheet sandwiched between glass layers.
