Zusammenfassung:	An identification card protected against external chemical influences of the environment, having blocking layers in its outer areas to prevent plasticizers and other chemical substances which reduce stability and durability from penetrating inside the card. The blocking layers consisting of PETP (polyethylene terephtalate), PE (polyethylene), paper or other chemically resistant materials are located on the surface of the card, preferably in compound films with the construction PVC/blocking layer/PVC, between which the card core bearing the personalization data is laminated in. Thus partial embeddings such as signature stripes, magnetic stripes, photos, etc. can also be provided in the surface layer, the inner PVC layers of the card still being optimally protected by the blocking layers against the negative consequences of the influence of plasticizers, such as fatigue fracture and bending tears.
