There are provided laminated bodies or laminated body-containing windows, which comprise isotropic aqueous solutions obtained by dissolving a water-soluble polysaccharide derivative having nonionic amphipathic functional groups in an aqueous medium composed of water and an amphipathic substance, laminated between plates that are at least partially transparent and allow direct vision of the isotropic aqueous solutions, wherein there are added to the isotropic aqueous solutions in appropriate amounts ultraviolet absorbers comprising nonionic or ionic benzophenone derivatives or benzotriazole derivatives which are highly weather resistant and uniformly dissolve in the isotropic aqueous solutions. The isotropic aqueous solutions are transparent and become opaque upon irradiation with light, and exhibit stable reversible change, in order to provide vastly improved weather resistance to the laminated bodies against exposure to sunlight rays over prolonged periods of time.
L'invention concerne un laminé composé d'une couche de solution aqueuse isotrope d'un dérivé polysaccharide soluble dans l'eau ayant une groupe fonctionnel amphiphile dans un milieu aqueux contenant de l'eau et une substance amphiphile et, étant présents sur ses deux côtés, des substrats dont au moins une partie est transparente et permet l'observation directe de la solution aqueuse isotrope, cette dernière comprenant une dose appropriée d'un agent absorbant les ultraviolets renfermant un dérivé benzophénone ou benzotriazole ; et une fenêtre comprenant le laminé. Ce dernier, qui comprend la solution aqueuse isotrope qui est transparente et qui se trouble du fait du rayonnement d'une lumière à changement réversible stable, présente une remarquablement meilleure résistance aux intempéries et peut, par conséquent, supporter une longue exposition à la lumière solaire.
