Abstract
Abstract The present invention concerns our discovery that decorative sheets and coverings comprising polyvinyl chloride and having substantially non-migratable through-color images may be prepared using cationic dyestuffs. These coverings may be prepared by providing a variety of polyvinyl chloride-containing substrates with image compositions comprising cationic dyestuffs and a suitable binder, and then treating these materials such that the cationic dyestuffs migrate into the substrate. Through-color images are obtained which are substantially non-migrating, even under severe conditions.
