Provided are solar control laminates comprising a solar control film and a polymeric sheet. The solar control film comprises a polymeric film coated with a coating comprising inorganic infrared absorbing nanoparticles. Preferably, inorganic infrared absorbing nanoparticles comprise nanoparticles of antimony tin oxide (ATO), indium tin oxide (ITO), lanthanum hexaboride (LaB) or mixtures thereof. Optionally, the solar control laminate also comprises a rigid sheet, such as a glass sheet.

Solar control laminate

Provided is a solar control composition comprising an infrared absorbing phthalocyanine compound or naphthalocyanine compound and a resin having a modulus from 20,000 psi (138 MPa) to 1000 psi (7 MPa) and solar control laminates comprising the solar control composition of the invention.

Solar control laminates

Provided are compositions comprising infrared absorptive inorganic nanoparticles and a matrix material and methods to produce the compositions. The infrared absorptive inorganic nanoparticles preferably include antimony tin oxide (ATO), indium tin oxide (ITO), or mixtures thereof. Also provided are polymer blends, polymeric films and sheets, solar control laminates, and processes to produce the polymer blends, polymeric films and sheets and solar control laminates.

Nanoparticulate solar control concentrates

Provided is a solar control composition comprising an infrared absorbing phthalocyanine, naphthalocyanine or rylene compound and an ethylene acid copolymer or an ionomer of an ethylene acid copolymer. Further provided are solar control laminates comprising the solar control composition of the invention.

The present invention is an infra red (IR)-blocking coating and a process for applying the IR-blocking coating onto the surface of a polymer. The process comprises the steps of dispersing an IR-blocking material in a mixture of solvent comprising a dissolved polymer and using standard printing processes to coat at least a portion of the surface of a bulk polymer, preferably a sheet or film. The present invention also provides safety glass laminates whose polymer interlayers have improved adhesion to glass in addition to light blocking properties.

Process for preparing polymeric films useful for blocking the transmission of near infra red light

The present invention is a translucent interlayer, or a laminate obtained therefrom, that has low clarity, high haze, and light transmission of at least 60 percent wherein the aesthetic qualities of etched or sandblasted glass are substantially recreated. In addition, a laminate of the present invention provides the safety characteristics of laminated safety glass. In addition, the process for making the translucent laminates of the present invention can eliminate the safety and environmental concerns related to sandblasting or etching processes.
