The invention provides a coating for an anti-counterfeiting self-adhesive label with a PVC base material. The coating comprises the following components by weight percent: 10% to 20% of organic silicon resin, 4% to 10% of alkyd resin, 0.01% to 0.5% of an assistant and 70% to 85% of a solvent. Compared with the prior art, the coating has the beneficial effects that the coating is convenient to prepare and utilize, coating adaptability is good, adhesion fastness is good, the molding temperature range is wide, the problem that the a nickel plate is stuck and blocked by the coating is eliminated, and the holographic anti-counterfeiting effect is prominent.
