An optical sheet suitable for use in a laminate comprising at least one glazing component. The optical sheet comprises a non-metallic multi-layer optical film that has multiple optical layers, and can be, for example, a solar energy reflective film (e.g., an infrared radiation reflective film). The multiple layers are thermally and/or otherwise fused together along all, substantially all or at least a substantial portion of the peripheral edge of at least the optical film, so as to prevent or at least substantially reduce the occurrence or degree of delamination of the multiple layers along all, substantially all, or the substantial portion of the peripheral edge of the optical film. At least the optical film can be dimensioned such that, when bonded to a glazing component, all, substantially all or at least the substantial portion of the peripheral edge of at least the optical film is positionable so as to be co-extensive with or substantially co-extensive with a corresponding portion of the peripheral edge of the glazing component to which the optical sheet is to be bonded.

Laminates and methods of making same

A transparent solar control film may have a single or multiple layer core that includes at least one layer of an orientated thermoplastic polymer material. Infrared radiation absorbing nanoparticles that preferentially absorb at least about 100 times more infrared radiation than visible radiation may be dispersed within the at least one layer of an oriented thermoplastic polymer layer. The transparent solar control film may have a haze value of less than about 5 percent.

Solar control film

A birefringent dielectric multilayer film that reflects in a wavelength region of interest, and preferably reflects at least 50% of light in a band at least 100 nm wide, preferably positioned between wavelengths from about 700 nm to about 2000 nm. The film is heat set to render the film capable of shrinking to conform without substantial wrinkling to a substrate having a compound curvature. The film may be laminated to form a wide variety of non-planar articles.

Wrinkle resistant infrared reflecting film and non-planar laminate articles made therefrom

Multilayer polymeric films and other optical bodies are provided which is useful in making colored mirrors and polarizers. The films are characterized by a highly uniform change in color as a function of viewing angle.
