  • Patent number: 5589324
    Abstract: The photographic element having an antistatic layer composed of a polymer entity of (a) a water-soluble, electrically conductive polyelectrolyte, e.g., poly(sodium styrenesulfonate) homopolymer, and (b) a polymer derived from a polymerization of a monomer, such as a polyfunctional aziridine, in the presence of the polyelectrolyte. When applied to the surface of a support as a component of a coating mixture, the monomer polymerizes and entraps the polyelectrolyte molecules forming a distinct and permanent antistatic layer on the support. The electrically conductive polyelectrolyte molecules confer antistatic protection for photographic materials.
