[0014] A method for preparing a thermal transfer ribbon, comprising the following steps:
[0015] ① Coat the ink layer on one side of the substrate, the coating amount is 2.5~3g / m 2 , drying, and enter the next process;
[0016] ② Coat the back coat on the other side of the substrate, the coating amount is 3.5~5.5g / m 2 , drying, that is, ribbons.
Embodiment 1
[0018] The base tape used in the present invention is a PET film, each layer is coated according to the following steps, and finally a thermal transfer carbon tape is obtained.
[0019] 1) ink layer
[0020] After mixing the raw materials in the following weight ratios, use a coater to coat one side of the above-mentioned substrate at room temperature, and the coating amount is 2.5g / m 2 , drying after coating to form an ink layer, and entering the next process;
[0021] Ink layer composition:
[0022] 15 parts by weight of resin;
[0023] 10 parts by weight of wax;
[0024] 12 parts by weight of colorant;
[0025] Auxiliary 2 parts by weight.
[0026] 2) Back coating
[0027] After mixing the raw materials in the following weight ratios, use a coater to coat the surface of the above substrate at room temperature, and the coating amount is 3.5g / m 2 , drying after coating to form a back coating, that is, a ribbon;
[0028] Backcoat Composition:
[0029] 10 parts by weig...
