Abstract
Printing using two colors can be performed by a thermal print head. A base member, a thermosensitive color developing material layer formed by applying a thermosensitive color developing material on the entire surface of the base member, and a thermosensitive decolorizing material layer formed by applying a thermosensitive decolorizing material having a decolorizing temperature different from a color developing temperature of the thermosensitive color developing material on the entire surface of the thermosensitive color developing material layer, are provided.
Claims6
A print medium comprising:
- a base member;
- a first thermosensitive color developing material layer formed of a first thermosensitive color developing material;
- and
- a second thermosensitive color developing material layer formed of a second thermosensitive color developing material having a different reaction temperature from a reaction temperature of the first thermosensitive color developing material.
A print medium unit comprising:
- a print medium having a base member and a first thermosensitive color developing material layer formed of a first thermosensitive color developing material;
- and
- an ink ribbon for thermally transferring an ink to the print medium;
- wherein the ink ribbon has a different reaction temperature from a reaction temperature of the first thermosensitive color developing material layer.
A print medium unit comprising:
- a print medium having a base member and a second thermosensitive color developing material layer formed of a second thermosensitive color developing material;
- and
- an ink ribbon for thermally transferring an ink to the print medium;
- wherein the ink ribbon has a different reaction temperature from a reaction temperature of the second thermosensitive color developing material layer.
