Abstract
The invention relates to a protective coating for documents such as a passport, an identification card, or plastic cards such as credit cards, access cards, etc., which is highly resistant to abrasion while having as little influence as possible on the structure of the substrate, i.e. which keeps flexible substrates flexible, and can be applied prior to the document being individualized. The inventive document comprises a flexible or rigid substrate made of a textile material, paper, and/or plastic, particularly film-type or card-type plastic, and a protective coating and is characterized by the fact that said protective coating is less than 0.02 mm thick and is deposited on the substrate particularly from the gas phase and/or plasma phase.
