  • Patent number: 5856060
    Abstract: An image forming material is disclosed which comprises a support and provided thereon, an image forming layer and an image protective layer in that order, the image forming layer containing a colorant and a first binder resin, and the image protective layer containing fine particles in an amount of 2 to 150 mg/M.sup.2 and a second binder resin and having a thickness of 0.03 to 1.0 .mu.m, wherein an image is formed by exposing the material to a high density energy light to reduce adhesion between the image forming layer and the support and then removing the image forming layer at exposed portions.

  • Patent number: 5691103
    Abstract: An image forming material is disclosed which comprises a support and provided thereon, an image forming layer containing a colorant, the image forming layer being hardened, wherein an image is formed by imagewise exposing the image forming layer to a high density energy light to reduce an adhesive force between the image forming layer and the support and by removing the exposed portions of the image forming layer of the image forming material.

  • Patent number: 5631117
    Abstract: A method of manufacturing a light-heat converting heat mode recording material comprises a first support having thereon a cushion layer, an intermediate layer and an image forming layer in that order, the material comprising a light-heat converting substance, the method comprising the steps of a) providing a first unit comprising a first support; b) providing a second unit comprising a second support having thereon the image forming layer; c) superposing the second unit on the first unit so that the image forming layer is in close contact with the first unit; and d) separating the second support from the image forming layer to form the recording material, wherein the second support has a releasing layer containing a cross-linked compound on the image forming layer side, the releasing layer being insoluble in a coating solvent for both the intermediate layer and the image forming layer, and provided between the second support, or has a releasing layer containing a fluorine-containing compound or a long chain a

  • Patent number: 5512931
    Abstract: A process for image forming by heat transfer method is disclosed. The process comprises the steps of (1) transferring an ink image from an ink layer of an ink sheet, which comprises a support and an ink layer provided on the support, to a surface of an intermediate image receiving layer of an intermediate image receiving sheet, which comprises a support and an image receiving layer provided on the support, by imagewise heating the ink layer, and (2) re-transferring the ink image transferred on the intermediate image receiving layer to a secondary image receiving sheet,In the above process, the ink layer comprises a coloring material and a homopolymer or a copolymer comprising a repeating unit derived from a monomer represented by the following Formula 1 or a phthalic polyester formed by polymerization of phthalic acid and a polyol; ##STR1## wherein R.sub.1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms; R.sub.2, R.sub.3 and R.sub.
