    摘要： The present invention relates to a cover film for hard copy printing paper which can easily form a colorless and transparent protecting layer on the surface of, for example, a printing paper on which a color picture image is printed. The cover film for hard copy printing paper is such one that the cover film for hard copy printing paper is formed on the surface of a hard copy printing paper on which the printing is carried out by the sublimation transfer method and the cover film is designed to include at least one layer the glass transition temperature of which is selected to be higher than 40.degree. C. and whose water absorbing ratio (ASTM D570) is selected to be lower than 2%, whereby even under high temperature and high humidity, the bad influence exerted by the movement of a dye can be removed.

    摘要： A cover film for a sublimation transfer type hard copy of the present invention is a cover film which is melt bonded by heat on the surface of a hard copy printing paper in which a picture image is formed on the surface thereof by selectively transferring a sublimation dye. The cover film includes a resinous layer containing a metal compound selected from Al, Mg, Ca and Sn. This cover film is capable of producing magenta color of high color saturation by arbitrarily controlling the coloring of reddish dye to be shifted to the blue side and can also protect the surface of the printing paper.Furthermore, the present invention relates to a cover film which is melt bonded by heat on the surface of a hard copy printing paper in which a picture image is formed on the surface thereof by selectively transferring a sublimation dye. This cover film includes a layer mainly formed of a phosphor whitener and a resin to increase a whiteness degree of a portion which is not colored so that a picture image is made clear and which can prevent the color of dye from being faded.

    摘要： The present invention relates to an ink ribbon for sublimation transfer type hard copy which is used to produce as a hard copy a still picture image such as a picture image taken by a video camera, a television picture image and so on. The ink ribbon for sublimation transfer type hard copy of this invention comprises a heat-resistant plastic film base or a plastic film base having formed thereon a heat-resistant treating layer and coating layer of sublimation dye formed on the plastic film base. According to this ink ribbon for sublimation transfer type hard copy, it is possible to protect the film base from being shrunk and producing a bubble spot therein due to heat generated upon transfer, etc. Accordingly, a quality of a transferred picture image can be improved.
