Near-infrared Shielding Material, Laminate Including the Same, and Optical Filter for Display Including the Same

To provide a laminate which is excellent in heat-ray shielding properties, transparency, and weatherability and is suitable for use in laminated glass; and an optical filter for display which has excellent near-infrared shielding properties and is excellent in transparency, weatherability, and display performance. The laminate comprises two substrates and an intermediate layer sandwiched therebetween and bonded and united thereto, wherein a heat-ray shielding layer, a plastic film, and an intermediate layer have been interposed between the intermediate layer and the substrate. The heat-ray shielding layer comprises tungsten oxide and/or composite tungsten oxide, and the intermediate layer comprises a compound showing maximum absorption in the wavelength region of 200-500 nm. The optical filter for displays comprises a near-infrared shielding layer containing tungsten oxide and/or composite tungsten oxide and at least one other functional layer containing a compound showing maximum absorption in the wavelength region of 200-500 nm.

The present invention relates to a near-infrared shielding material having near-infrared shielding function, a laminate including the shielding material useful in a safety glass such as laminated glass or a film-reinforced glass (e.g., bilayer, window film) which has excellent impact resistance and penetration resistance (resistance to passing through) and is effective in prevention of crimes and which is used in an automobile, a railway vehicle, a building and a showcase, an optical filter for display, and a display provided with the optical filter, especially plasma display panel (PDP).
