Abstract: A process for the production of a liquid crystal display device having a color filter comprising:providing an assembly comprising, in order, a first support member, a plurality of first electrodes secured to the first support member, a liquid crystal layer, at least one second electrode and a second, substantially transparent support member, the assembly further comprising an imageable layer which, upon exposure to actinic radiation, can form three different colors, this imageable layer being disposed between the first and second support members; andexposing the assembly to actinic radiation so as to produce in the imageable layer a plurality of filter elements of first, second and third colors, said filter elements being aligned with the first electrodes, thereby forming a color filter lying between the first and second support members.

Abstract: Diffusion transfer color films and processes are disclosed which use dye developer chemistry to form at least one color record and which use image dye-releasing thiazolidine chemistry to form at least one of the other color records.

Abstract: The blue light response of solid state photosensitive devices such as silicon based charge-coupled devices (CCDs), charged-injection devices, photovoltaic devices and the like is enhanced by applying to the surface thereof a thin layer which includes a first, or donor, dye which absorbs efficiently in the blue region of the spectrum and a second, or acceptor, dye which absorbs efficiently in the green region of the spectrum, there being substantial overlap between the emission spectrum of the donor and the absorption spectrum of the acceptor. The relative concentrations of the dyes are controlled such that the donor dye transfers energy nonradiatively to the acceptor dye which is caused to fluoresce thereby emitting light in the region where the device has substantial photoresponse.

Abstract: The present invention is directed to photosensitive elements and to diffusion transfer film units employing said elements wherein said photosensitive element includes a plurality of essential layers, including a first photosensitive silver halide layer and a second photosensitive silver halide layer, said first and second silver halide layers being sensitized to substantially the same spectral absorption range; a spacer layer intermediate and contiguous to said first and second silver halide layers, said spacer layer consisting essentially of inert particles which are substantially non-swelling in alkali, and substantially non-film forming; wherein said inert particles are equal to or less than the average diameter of the silver halide grains in said first and second silver halide layers and wherein said silver halide grains are 2.

Abstract: The present invention relates to photography and, more particularly, to diffusion transfer process photographic film units which comprise a photosensitive element adapted to provide, by diffusion transfer photographic processing, selective dye image recordation of incident actinic radiation as a function of the point-to-point degree of photosensitive element exposure, which film unit includes a plurality of photosensitive units each exhibiting a predetermined gamma of substantially the same value and within a range of 1.1 to 1.
