SELF-SUPPORTING SHEET-LIKE ARTICLE WITH SUPERIOR ANTISTATIC CHARACTERISTICS

摘要

A self-supporting sheet-like article is described which is comprised of a substrate layer and an antistatic coating applied to at least one surface of the substrate layer. The antistatic coating is produced by the treatment of at least one surface of the substrate layer with an electrical corona discharge which runs between a live electrode and a counter electrode. Simultaneously, i.e. during the corona discharge, an aerosol is introduced into the corona discharge area, which aerosol contains an antistatic agent. Furthermore, a procedure for the production of a self-supporting sheet-like article with an antistatic coating as well as a firmly adhering antistatic coating on a polymer substrate are described.
