WATERFAST BACKPRINT INK JET RECEIVER MEDIUM

摘要

Provided is an ink jet receiving medium comprising a transparent substrate and a dual layer ink receiving system thereon. The top layer, which first contacts the ink, comprises a mixture of non-porous and porous silica, as well as a blend of a vinylacetate copolymer and a fully hydrolyzed polyvinyl alcohol. The second layer, or lower layer, comprises a water soluble polymer and a quaternized ammonium resin. The resulting ink jet receiving sheet permits the ink to quickly pass through the top layer and be absorbed in the lower or second layer, and become locked, thereby creating a waterfast ink jet print.
