ABSTRACT:
The present invention is directed an oriented, foamed article having an ink-receptive surface, and a method of making the article. The invention provides a printable substrate comprising at least one high melt-strength, oriented polypropylene foam layer having an ink-receptive surface. The high melt-strength polypropylene having a melt strength of 25 to 60 cN at 190° C. The ink-receptive surface may comprise and oxidizing treatment, such as corona or flame-treatment of the foam surface, or may comprise an ink-receptive coating, such as a primer coating, on the foam surface.The oriented foam article is particularly useful in the preparation of printed security documents such as currency, stock and bond certificates, birth and death certificates, land titles and abstracts and the like.
