FIELD: physics.
SUBSTANCE: optical protective element comprises optical storage material made from mix of photo-responsive polymer and, at least, one additive. Set of data or images with different directions of polarisation are written one on the other in optical storage layer by polarised light.
EFFECT: higher data density, reliable protection against counterfeit.
