Abstract

A security thread having an enhanced security feature is produced by forming a water-soluble ink layer on a selected portion of the surface of a transparent film; depositing a metal layer on the film surface including the water-soluble ink layer; and washing the metal deposited film with water to remove the portion of the metal layer deposited on the water-soluble ink layer.
