Abstract: An image is formed on an architectural surface by applying to the surface, in order: a rear electrode layer; a light-transmissive front electrode layer; a photoconductive layer disposed between the front and rear electrode layers; and an electro-optic layer disposed between the front and rear electrode layers. A potential difference is applied between the front and rear electrode layers and the front electrode layer is imagewise exposed to radiation which causes a change in the conductivity of the photoconductive layer, thereby causing an imagewise change in the optical state of the electro-optic layer. Films for application to architectural surfaces are also provided.

Abstract: A flexible composite is disclosed that includes a light-transmissive layer of an intumescent material and at least one light transmissive moisture barrier in contact with at least one surface of the layer of intumescent material, the intumescent material including an amine or amide containing compound. The composite may provide fire-resistant properties when included in flexible devices or materials requiring transparent top layers, such as electro-optic films or architectural electronic paper based products containing flammable solvents.
