Abstract: An exposure and pressure applicator device for use in printing an image onto an imaging media, containing photosensitive microcapsules comprising: an exposure means adjacent to the imaging media comprising at least one exposure-producing element which image-wise exposes the imaging media providing a latent image thereon; a pressure applicator means containing at least one point contact element to apply a uniform rupturing force to the exposed imaging media; and motive means for effectuating synchronous movement of both exposure means and pressure applicator means relative to the imaging media, are described.

Abstract: A photosensitive material includes a support having microcapsules and a color correction dye on its surface. The microcapsules include first, second and third sets of microcapsules, each set containing an internal phase. The first set of microcapsules is sensitive to red light and is associated with a cyan image-forming agent, the second set of microcapsules is sensitive to green light and is associated with a magenta image-forming agent, and the third set of microcapsules is sensitive to blue light and is associated with a yellow image-forming agent. The cyan, magenta and yellow image forming agents are respectively soluble in the internal phases of the first, second and third sets of microcapsules whereas the color correction dye is insoluble in the internal phase. The first, second and third sets of microcapsules are present in one or more layers containing a binder on the surface of the support. The color correction dye absorbs at least one of red, green, and blue light.

Abstract: A method is described for forming a transparency containing images having high color density comprising the steps of:forming an imaging sheet, said imaging sheet comprising a substrate having a layer of microcapsules on the front surface and on the back surface thereof, of microcapsules containing an internal phase which undergoes a physical change upon exposure to actinic radiation, and a color forming agent which is capable of reacting with a developer-containing resing to form a visible image thereon;simultaneously image-wise exposing said microcapsules on said front and said back surfaces of said imaging sheet to actinic radiation;assembling said exposed imaging sheet between a pair of developer sheets wherein each of said developer sheets comprises a substrate having a layer of developer-containing resin on one surface thereof, said layer of developer-containing resin on each of said developer sheets contacting the adjacent surface of said imaging sheet;subjecting said assembly to a uniform rupturing and

Abstract: An imaging sheet used for achieving color balance in a full-color imaging system is disclosed. The sheet is characterized by utilizing three sets of microcapsules, each containing a different colorless image-agent and a photohardenable or photosoftenable composition, and a corrective dye associated with the substrate. Association of the corrective dye with the substrate achieves color balance by equalizing the speed of the different colorless color-forming microcapsules.

Abstract: A photosensitive material comprising a support having a layer of microcapsules on the surface thereof, said microcapsules containing a color precursor and a photohardenable or photosoftenable composition, and said support being a highly reflective, non-difuse polymeric film or coated paperstock.

Abstract: Processes for forming metal patterns such as electric circuits and photosensitive materials useful therein are disclosed wherein a layer of photosensitive microcapsules is used to form a pattern of an adhesive, a metallic pigment, a metal salt or a reducing agent by exposing the layer of microcapsules to actinic radiation and transferring the internal phase to a support member. A pattern of the pigment salt or reducing agent is thereby formed on the support member which is treated with an electroless plating solution to form the metal pattern.

Abstract: A method for treating an imaging sheet is disclosed. The method includes the steps of providing an imaging sheet having coated on one of its surfaces a layer of microcapsules, the microcapsules containing a radiation curable composition and having an image-forming agent associated therewith, heating the sheet; and image-wise exposing the layer of microcapsules to actinic radiation; wherein the heating step is performed prior to or after the image-wise exposing step. The method reduces or removes damage defects on the imaging sheet and, in some instances, extends the dynamic range of the image-forming agents.

Abstract: A developer sheet useful in forming reproductions which have a controllable gloss finish or in forming transparencies comprising a support having a layer of a finely divided, thermoplastic, developer material on the surface thereof, said developer material being capable of reacting with a color precursor to produce a visible image and being capable of coalescing into a thin film which imparts gloss to said image upon application of heat and/or pressure.The developer sheet comprising a support having a layer of a finely divided thermoplastic developer material on the surface thereof can additionally comprise oil-containing microcapsules such that upon microcapsule rupture, the oil plasticizes the developer material.
