    • A heat-transfer recording medium is disclosed, which produces no lowering in transfer density even when the medium is used under such higher-temperature conditions as in a facsimile equipment and is capable of providing an easily readable transferred image having a low surface gloss, as well as having an excellent keep-secrecy and producing few voids. The recording medium comprises a support; a heat-transfer layer, provided on the support, comprising a thermo-fusible substance and a colorant; and a non-transfer layer which is interposed between the support and the transfer layer and comprises a colorant, a thermoplastic polymer selected from the following Group A and a thermoplastic polymer selected from the following Group B:Group A: an .alpha.-olefin polymer, an .alpha.-olefin-maleic anhydride copolymer, an .alpha.-olefin-alkyl acrylate and methacrylate copolymer, an .alpha.-olefin-vinyl acetate copolymer, an .alpha.-olefin-acrylic or methacrylic acid copolymer, a vinyl acetate polymer, an alkyl acrylate or methacrylate polymer, a acrylic or methacrylic acid polymer and a styrene-containing polymer;Group B: A polyester resin, a polyurethane resin, a polyvinyl chloride resin and an epoxy resin.

    • A method of image formation using mask for exposure to form an image on photographic paper is disclosed. The mask is composed of transferred images of the dyes of yellow, cyan and magenta. The spectral absorption peak wavelength of the dye is set in a range close to the wavelength at the maximum value of each of the regular, orthochromatic and panchromatic spectral sensitivities of the photographic paper to be used. In the spectral absorption of cyan of the mask for exposure, the absorbance of the wavelength at the maximum value of each of the regular and orthochromatic spectral sensitivities of the photographic paper to be used, is set at a value not more than a predetermined value. In the spectral absorption of yellow of the mask for exposure, the absorbance of the wavelength at the maximal value of each of the orthochromatic and panchromatic spectral sensitivities of the photographic paper to be used, is set at a value not more than a predetermined value.
    • 公开了一种使用用于曝光以形成照相纸上的图像的掩模的图像形成方法。 该掩模由黄色,青色和品红色染料的转印图像组成。 染料的光谱吸收峰值波长被设定在接近所使用的相纸的常规,全色和全色光谱灵敏度的最大值的波长附近的范围内。 在用于曝光的掩模的青色的光谱吸收中,将要使用的相纸的常规和正色光谱灵敏度中的每一种的最大值处的波长的吸光度设定为不大于预定值的值。 在用于曝光的掩模的黄色的光谱吸收中,将要使用的相纸的每个正色和全色光谱灵敏度的最大值处的波长的吸光度设定为不大于预定值的值。
