Title:
THERMAL TRANSFER PRINT RIBBON CONTAINING SLICED MULTI-LAYER INORGANIC NANOPARTICLES OR LAYERED METAL DUAL LAYER HYDROXIDE NANOPARTICLES, AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/123318
Kind Code:
A3
Abstract:
The present invention relates to a thermal transfer print ribbon containing sliced multi-layer inorganic nanoparticles or sliced layered metal dual layer hydroxide nanoparticles, and a manufacturing method thereof. More specifically, the present invention relates to a thermal transfer print ribbon having improved heat resistance, image uniformity and wear resistance, compared with a sublimated heat transfer print ribbon that has a heat-resistant lubricating layer and a first adhesive layer formed on a rear surface of a base film; and a second adhesive layer, a transfer ink layer and a transfer protective layer formed over the base film, through the addition of multi-layer inorganic nanoparticles or layered metal dual layer hydroxide nanoparticles in slice form into the heat-resistant lubricating layer, the transfer ink layer and the transfer protective layer. With the thermal transfer print ribbon according to the present invention, excellent heat resistance of the heat-resistant lubricating layer protects the print ribbon from thermal deformation and being torn off and causes no damage to the thermal transfer head during image printing; substantially improved durability of the transfer protective layer reduces the wear on the print ribbon; and uniformity in respective layers enhances the print sensitivity, thereby bringing benefits to the image print quality as well as to the cost.
