A contact reflex manifold imaging process is provided wherein a manifold set comprising an electrically photosensitive imaging layer in a screen pattern releasably resides on a transparent donor sheet and is in contact with a transparent receiver sheet. A master to be copied is placed in contact with one side of the manifold set and is exposed to electromagnetic radiation to which the imaging layer is sensitive by passing the electromagnetic radiation through the manifold set while the imaging l...

A system which transforms a cholesteric liquid crystalline material from its Grandjean or "disturbed" texture state to its focal-conic or "undisturbed" texture state by an applied electrical field, and an imaging system wherein a cholesteric liquid crystalline member is imaged in a desired image configuration by the electric field-induced texture transition system.

An imaging system wherein an imaged migration imaging member, this member typically having a substrate, a softenable layer, and migration marking material with some of the marking material migrated toward the substrate or disrupted in an image-wise configuration, is provided and the member is electrically charged to produce an electrostatic latent image on the member.

Images are formed on direct positive photographic material in a single white-light exposure through the use of a master sheet which consists essentially of a selectively transmissive filter layer which allows transmission only of longer wave length light which is effective in reversing the prefogged direct positive material, and indicia disposed with respect to the filter layer to form in the master substantially totally opaque elements and substantially totally white light transmissive elements...

An imaging system which imagewise transforms a cholesteric liquid crystalline material from its Grandjean or "disturbed" texture state to its focal-conic or "undisturbed" texture state by an imagewise applied electrical field whereby a cholesteric liquid crystalline member is imaged in a desired image configuration by the electrical field-induced texture transition system.

A system wherein a film of liquid crystalline material is exposed to ultraviolet radiation thereby producing a visible image. BACKGROUND OF THE INVENTION This invention relates to imaging systems, and more specifically to an imaging system wherein the imaging member comprises a liquid crystalline material. Various methods of forming visible images in response to patterns of lights and shadows are well known. Photography and blueprinting are examples of chemical methods wherein incident light ind...

A finely-divided low melting toner comprising a colorant, a thermoplastic resin comprising a vinyl resin, a solid metal salt of a fatty acid, and a solid additive having a melting point between about 115.degree. F. to about 270.degree. F. comprising a benzoate, a sulphonamide or a polychlorinated polyphenyl compound.

An image carrying cylinder portion and optical system for use in the support of an image. The cylinder portion is transparent and light image is flowingly projected along a fixed path through the diameter of the cylinder from the inside to the outside surface. The cylinder portion is rotated through the light path along which the light image is projected in sychronism, flowing with the moving cylinder portion so that both the cylinder portion and the light image move through an image plane of th...

An electrophoretic imaging system utilizing a pair of electrodes and a suspension of electrically photosensitive particles in an insulating carrier liquid is described in which at least one of the electrodes is porous and contains the suspension in the pores. In one embodiment, the electrodes are spaced adjacent each other and the suspension is fed through the porous electrode into the inter-electrode space during photoelectrophoretic image formation.

A system transforming an optically negative liquid crystalline substance to an optically positive liquid crystalline mesophase by an applied electrical field, and an imaging system wherein the electrical field-induced transition images a liquid crystalline member.
