  • Method of thermal transfer recording on marking film
    Patent number: 5611881
    Abstract: A thermal transfer recording method forms a pattern on a marking film, which is a plastic film containing a heat adhesive resin or a plastic film on which a heat-sensitive image-receiving layer, composed mainly of a heat adhesive resin, is formed. A thermal transfer ribbon is prepared by forming a heat-melting ink layer on one surface of a substrate and is used to form the pattern on the marking film. The above method permits the facile formation of a fine or complicated multi-color character or pattern on a marking film in a quick thermal transfer operation at a low cost.
