    Abstract: An imaging medium comprises a substrate carrying a color-change layer. This color-change layer comprises two layers or phases comprising two color-forming reagents which react upon heating to cause a change in the color of the layer. The color-change layer is deactivated by exposure to actinic radiation such that after deactivation it no longer undergoes its thermal color-change. The color-change layer is detachable from the substrate by heating to a temperature lower than required to cause the color change, so that upon contact of the imaging medium with a receiving sheet each individual pixel of the color-change layer may be left attached to the substrate, transferred to the receiving sheet but left uncolored, or transferred to the receiving sheet and colored to a color level determined by the energy used in the associated thermal print head element.

    Abstract: A method for manufacturing a pattern sheet for plate-making capable of easily forming a positive image through the use of a photographic negative film. In this method, as a first step, a negative film with a printed negative image is placed on a surface of a light transmission sheet carrying a photosensitive color-developing layer containing a photosensitive color-developing material which makes a color development in response to light. Further, as a second step, the light is applied thereto from the negative film side after the first step. As a result of the application of the light, a color development takes place in the photosensitive color-developing layer due to the light passing through the negative image, thus causing a positive image to be formed on the surface of the light transmission sheet.

    Abstract: This invention relates to negative working color proofing sheet constructions which, upon exposure to an actinic radiation source through a screened image, can accurately reproduce said image. The construction is useful as a color proofing film which can be employed to accurately predict the image quality from a lithographic printing process. The image is produced by forming a composite of a receiver sheet, an adhesive layer, a color layer and cover sheet. Upon imagewise exposure, a negative image appears on the receiver base after dry peel apart development.

  • Patent number: 5763122
    Abstract: As adhesive films are used over first down half-tone images, air can be entrapped between the dots on the first down image and the after applied adhesive film (e.g., with the next down image layer). The presence of the air as bubbles between the dots creates additional areas of reflection and refraction at air/film interfaces. The use of thin layers of adhesive with the properties according to the present invention has surprisingly been found to prevent or reduce formation of bubbles and thereby maintain the critical optical properties necessary in a proofing material.

    Abstract: An image receiving sheet having a support sheet, an intermediate layer and an image receiving layer, wherein the intermediate layer comprises a polymer and a plasticizer having at least one ester bonds and molecular weight of 700 to 3,000. Otherwise, an image receiving sheet having a support sheet and an image receiving layer wherein the image receiving layer comprises a polymer and the plasticizer. A heat sensitive ink sheet has a heat sensitive ink layer which is formed of a heat sensitive ink material comprising colored pigment and thermoplastic resin such as amorphous organic polymer. An image forming method is conducted by using the heat sensitive ink sheet and one of the image receiving sheets by area gradation by the use of a thermal head or laser beam.

  • Patent number: 5725988
    Abstract: This invention provides an improved negative-working or positive-working, single sheet color proofing method which can accurately reproduce images by using colored, photosensitive layers on substrates which are then overcoated with partially developable adhesive layers. The final construction is useful in predicting the image quality from a lithographic printing process. The partial removal of the adhesive layers cleans out any background stain which may remain from the incomplete removal of the photosensitive layer.

  • Patent number: 5714303
    Abstract: The present invention provides new image forming methods. The image forming methods use a combination of a light-sensitive material and an image receiving material. The light-sensitive material comprises a support, a strippable layer and a light-sensitive polymerizable layer in order. The light-sensitive polymerizable layer contains silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound or a cross-linkable polymer. The light-sensitive polymerizable layer may further contain a colorant. An image forming method using the light-sensitive polymerizable layer containing no colorant comprises an exposing step, a developing step, a toning step and a transferring step. Another image forming method using the colorant-containing light-sensitive polymerizable layer comprises an exposing step, a developing step, a removing step and a transferring step.
