Abstract

Laser labels comprising: PA1 a) at least one polymer layer; PA1 b) a self-adhesive composition coated on one side of said at least one polymer layer; PA1 c) a printing ink applied by printing between said self-adhesive composition and said at least one polymer layer; and PA1 d) optionally a release paper or release film covering said self-adhesive composition; are useful for anti-counterfeit marking. The printing ink can be printed on the polymer layer before the self-adhesive composition is applied to the polymer layer.
