Embodiment 1
[0023] A dye-sublimation water-washed label printing ribbon, which is characterized by comprising a belt base, a back coat coated on one side of the belt base, and a thermal transfer layer coated on the other side of the belt base;
[0024] The thermal transfer layer is divided into two layers,
[0025] The lower layer is the pigment layer, which is composed of vinyl acetate resin and carbon black, in terms of mass percentage, 80% vinyl acetate resin and 20% carbon black; the upper layer is a sublimation dye layer, which is composed of water-based polyurethane resin and sublimation dye. In terms of mass percentage, 80% water-based polyurethane resin, 20% sublimation dye.
[0026] The above-mentioned preparation method of sublimation water washing label printing ribbon includes the following steps:
[0027] 1) Coat the back coating on one side of the tape base and dry it for later use;
[0028] When coating the back coating, based on the mass ratio, according to the ratio of MEK: back c...
