Label suitable for preventing black fabric from sublimation

The invention relates to the technical field of labels, and particularly discloses a label applicable to sublimation prevention of black fabric. The label specifically comprises backing paper, an adhesive layer, a base paper layer and an ink layer, a macromolecule anti-seepage interlayer is arranged between the adhesive layer and the base paper layer, and the adhesive layer is attached to the macromolecule anti-seepage interlayer to form an anti-seepage composite adhesive layer. The adhesive layer is prepared from the following raw materials in parts by weight: 90 to 120 parts of 4, 4 '-dicyclohexylmethane diisocyanate, 30 to 60 parts of isophorone diisocyanate, 100 to 120 parts of polyether/polyester blended polyol, 2 to 5 parts of a silane coupling agent and 20 to 30 parts of a chain extender. According to the anti-sublimation label, the physical isolation performance of the macromolecule anti-seepage interlayer and the solvent-free characteristic of the adhesive layer are utilized, and after the physical i
