A structurally stable composite structural chromogenic material and a preparation method thereof are provided. The structurally stable composite structural chromogenic material is formed by stacking a transparent thermoplastic polymer and a structural chromogenic material layer by layer and then thermally bonding the peripheral edges of the polymer into a whole, and the upper surface layer and the lower surface layer of the material are both thermoplastic polymers. The molded composite structure has relatively obvious structural color and good mechanical strength.

The invention relates to a device comprising: a first layer (11) of a thermoformable material that is inelastically deformable in a thermoforming temperature range, a second layer (1) of a viscoelastic material that is elastically deformable in a temperature range including a use temperature range of the device and the thermoforming temperature range, and wherein: the use temperature range is lower than the thermoforming temperature range, the first layer is bonded to the second layer, the thermoformable material is elastically deformable and more rigid than the viscoelastic material in the use temperature range, the thermoformable material is less rigid than the viscoelastic material in the thermoforming temperature range.

A polymeric film or laminate comprising the same is applied to at least a portion of a surface of an underlying article to provide, for example, desired surface characteristics. To assist in such application, a polymerizable composition is coated onto at least one of the surface of the polymeric film or the laminate and the surface of the article. The polymerizable composition is then polymerized with the polymeric film or laminate positioned thereover to form a sufficiently polymerized interlayer between the polymeric film or laminate and the underlying surface in resulting articles. Ease of removal and/or repair of polymeric film and laminates comprising the polymeric film that are so applied is facilitated.

A disclosed laminated automotive glazing for displaying an image comprises a first glass sheet; a first interlayer; a luminescent film having luminescent capabilities; a second interlayer; and a second glass sheet, wherein the luminescent film is reactive to an activating light wavelength, and wherein the second interlayer is transparent to the activating light wavelength and the first interlayer has a transparency at the activating light wavelength of equal to or less than 1.0%.
