ABSTRACT:
To protect photographic films from imaging by static discharges during manufacturing and customer use, copolymers of sulfonated monomers and primary amine monomers are coated on a film base and crosslinked with an aldehyde such as glutaraldehyde, or other colloid hardener giving a water-resistant, permanent, conductive (i.e., antistatic) layer.
