Definitions

  • This invention relates to a heat-transfer image recording medium and, particularly , to a heat-transfer image recording medium which, for example, produces no transfer-density-­lowering even when the medium is used under such high-­temperature conditions as in a facsimile equipment, in which heat is easily regenerated, and is capable of providing an easily readable printed image having a low surface gloss, as well as having an excellent keep-secrecy and producing few voids.
  • a heat-transfer image recording medium interposed a mat layer containing a resin and a mat pigment between a support and an ink layer so as to diminish the gloss of transferred images
  • another heat-transfer image recording medium interposed an anchor layer capable of forming fine unevenness on the pealable surface of an ink layer so as to diminish the gloss of transferred images.
  • the heat-transfer image recording media mentioned above may be able to diminish the gloss of transferred images, when using a heat-transfer image recording medium such as shown in Fig. 2, for example, with a facsimile equipment easily become regenerative in high-temperature conditions because the power is being switched ON all day long, there have been the following problems; Ink layer A containing a heat-fusible substance is liable to be peeled off from the inside of the ink layer so as to hinder ink layer A from peeling off from interface C between the ink layer A and a mat or anchor layer that is expected to be the peelable surface of ink layer A and, therefore, the thickness of ink layer A which is to be resultingly transferred onto a subject transferred medium becomes thinner so as to lower a transferred image density.
  • D is a support member.
  • a specific heat-transfer image recording medium which is comprised of a non-transfer layer containing a specific substance and being interposed between a support and a transfer layer, provides no density-lowering because a transfer layer is peeled off by breaking a coagulation around the interface between the transfer layer and the non-transfer layer even in high-­temperature conditions, and the recording medium can provide readily readable printed images because the surface gloss is low, as well as that the recording medium can be excellent in keep-secrecy, few in void production and high in resolving power, so that this invention have been achieved.
  • the heat-transfer image recording medium of the invention comprises a support, a transfer layer, provided on the support, containing a heat fusible substance and a colorant and a non-transfer layer which is provided between the support, and the non-transfer layer comprises a colorant, a polymer selected from the following Group A and a resin selected from the following Group B.
