Protection of printed images from gasfade

摘要

A print medium (2) having increased resistance to gasfade. An inhibitor (4) comprising a sulfur-containing polymer is incorporated into the print medium (2). The inhibitor is poly(1,4-phenylene sulfide) or poly(1,3-phenylene sulfide). The inhibitor (4) is present in at least a surface of the print medium (2) in a concentration from approximately 0.25% by weight per cm<2> of the print medium to approximately 30% by weight per cm<2> of the print medium. A method of forming the print medium (2) is disclosed as is a method of producing a printed image having increased resistance to gasfade.
