摘要:
The present invention relates to an image-receiving sheet used in combination with a heat transfer sheet having a dye layer containing a dye which is melted or sublimated by heating and passed onto said image-receiving sheet, characterized in that a sheet-like substrate (11) includes on its surface a dye-receiving layer (12) for receiving a dye coming from said heat transfer sheet, said dye-receiving layer (12) comprising a copolymer obtained by the copolymerization of (i) vinyl chloride, (ii) an acrylic acid type monomer and (iii) a linear polymer having a vinyl group at an end. The present sheet of such a structure as mentioned above is improved in terms of dyeability and weather-resistance-after-printing, and excels particularly in the storability of printed images.

An image-receiving sheet for thermal transfer printing comprising on a substrate an intermediate layer made primarily of a resin insoluble in organic solvents, and an image-receiving layer made primarily of a resin soluble in organic solvents and formed on the intermediate layer. This type of sheet is significantly improved in smoothness and blocking properties, enabling one to obtain print images of a very high quality, by thermal transfer printing, which are substantially free from the known problem relating to a missing transfer portion and which are high in the optical density for images as printed.

摘要:
The electrothermal transfer sheet of the present invention comprises a substrate sheet, at least one resistor layer formed on one surface of the substrate sheet and a dye layer comprising a heat-migratable dye and a binder, which is formed on the other surface of the substrate sheet. This transfer sheet is characterized in that at least one resistor layer has a positive resistance-temperature coefficient, the ratio R.sub.100 /R.sub.25 of the resistance value (R.sub.100) at 100.degree. C. to the resistance value (R.sub.25) at 25.degree. C. in the resistor layer is at least 1.2 and the ratio R.sub.200 /R.sub.100 of the resistance value (R.sub.200) at 200.degree. C. to the resistance value (R.sub.100) at 100.degree. C. in the resistor layer is at least 2.5. By maintaining these resistance-temperature characteristics, heat fusion bonding can be effectively prevented at the printing operation, and the printing sensitivity and image quality can be improved.
