PVC (polyvinyl chloride) heat shrinkage film ink

The invention discloses PVC (polyvinyl chloride) heat shrinkage film ink, which belongs to the technical field of peelable ink products and comprises an adhesion layer, a base material layer and an ink layer, the adhesion layer, the base material layer and the ink layer are sequentially stacked from bottom to top. And the adhesion layer is a polyoxyethylene layer, a polyvinylpyrrolidone layer or a polyvinyl alcohol layer. And the base material layer is a polyvinyl chloride heat-shrinkable film layer. The ink layer is ink prepared according to a preset ink formula, and the ink formula comprises the following components in parts by mass: 32 to 39 parts of modified epoxy acrylate, 10 to 13 parts of modified polyurethane acrylate, 10 to 25 parts of propylene oxide neopentyl glycol diacrylate, 7 to 12 parts of photoinitiator, 7 to 12 parts of barium sulfate, 3 parts of pigment, 0.5 part of defoaming agent and 10 to 15 parts of compound oligomer. The PVC heat shrink film ink solves the technical problem that an exi
