  • Patent number: 5455217
    Abstract: A thermal dye transfer system comprises a thermal dye transfer receptor element in intimate contact with a thermal dye donor sheet, said receptor element comprising a substrate having on at least one surface thereof in contact with said dye transfer donor sheet, a dye receptive receiving layer comprising a microporous polymer layer having insufficient pigment to provide an optical density of more than 0.2. The polymer layer may be transparentizable and provides thermal insulation.
    Type: Grant

  • Patent number: 5232892
    Abstract: A dye transfer receptor sheet suitable for thermal dye transfer imaging is described. The receptor sheet provides excellent image stability characteristics. The receptor sheet comprises a substrate with a receiving layer of a vinyl chloride containing copolymer which has a glass transition temperature between 50.degree. and 85.degree. C., preferably about 59.degree. and 65.degree. C., a weight average molecular weight between about 10,000 and 100,000, preferably between 30,000 and about 50,000 g/mol, a hydroxyl equivalent weight between about 1500 and 4000, preferably about 1890 and about 3400 g/mol, a sulfonate equivalent weight between 9000 and 23,000, preferably between about 11,000 and about 19,200 g/mol, and an epoxy equivalent weight between about 500 and 7000, preferably about 1200 and about 6000 g/mol.

  • Patent number: 5225392
    Abstract: A process for preparing an image utilizing both thermal dye and thermal mass transfer. A thermal transfer receptor element is utilized which contains a substrate and a vinyl chloride-containing copolymer which has a T.sub.g between about 50.degree. and 85.degree. C.; a weight average molecular weight between about 10,000 and 100,000 g/mol; a hydroxyl equivalent weight between 500 and 7,000 g/equiv.; a sulfonate equivalent weight between about 9,000 and about 23,000 g/equiv.; and an epoxy equivalent weight between about 500 and about 7,000 g/equiv., wherein a reactive amino-modified silicone has been chemically bonded to the vinyl chloride-containing copolymer.
