- the present invention relates to a thermal transfer ribbon having improved heat resistance, image uniformity and abrasion resistance of a sublimation thermal transfer ribbon by containing hydroxide nanoparticles in a peeled shape, and a method of manufacturing the same.
- an electrophotographic method, an inkjet method, a thermal transfer method, or the like is applied as a method of recording a color image.
- the thermal transfer recording method has been applied to a wide range of fields because of no noise during printing and easy maintenance of the device.
- a color image reproduced by an electrical signal is color-separated by a color filter, and separated into three images of red (G), green (G), and blue (B), and the separated three images. Is transmitted to the thermal head, which is a thermal element of the printer, in the form of an electrical signal.
- the thermal transfer head applies thermal energy to the opposite side of the surface on which the transfer ink layer of the thermal transfer printing ribbon is applied, thereby allowing three kinds of yellow, magenta, and cyan or the like.
- Four colorants, including black, are transferred to the ink receptor to obtain an image.
- the thermal transfer methods are largely divided into a melt type and a sublimation type.
- the melt method is a method in which a transfer ink layer is heated and melted by a thermal element and then transferred to the receiving layer and solidified. In the transfer process, not only the colorant but also the binder component is transferred to the receiving layer to express continuous gradation.
- the sublimation type is a dye diffusion type in which a transfer layer is formed of a thermal sublimable dye and a binder resin, and only dye is transferred to a card in proportion to the thermal energy applied by the thermal element to form an image.
- Such a sublimation type has an advantage that it is easy to express a continuous gray level in the transfer image because the amount of dye to be transferred is controlled in proportion to the applied thermal energy.
- the sublimation thermal transfer method can obtain a very high quality image, and is also used to print an image that is electrically represented from a graphic design field or a color video camera through a color printer.

- the transfer ink layer of the printing ribbon is in contact with the lubricating heat-resistant layer, and the dye of the transfer ink layer gradually transfers to the lubricating heat-resistant layer for a long time.
- the dye on the lubricating heat-resistant layer contaminates the head when running the heat transfer head and damages the heat transfer head. Therefore, in order to reduce the dye transfer of the transfer ink layer and increase the flammability, the binder of the transfer ink layer should adhere the dye well, and the transfer ink layer surface should be uniform.

These fragile interfaces provide a penetration pathway when in contact with chemicals, resulting in poor chemical resistance. Since recording media such as cards are mainly stored in wallets and the like during daily life of users, they come into contact with chemicals such as plasticizers for a long time.
