Role of Zirconium Complexes to Produce Multiple Use Paper, 1996 Papermakers Conference Proceedings
Much resent research has been devoted to developing a paper sheet which is compatible with Ink Jet Printing. This may have obscured problems in other end use applications, which in aggregate consume far larger quantities of paper production than the ink jet printing segment. Modern papermakers with large volume production need to produce high performance economical, multiple application paper to meet the needs of various market segments, including ink jet printing, high ash content offset printing papers which print well, xerographic papers, and laser print papers, for example. Zirconium Complexes contribute key properties needed in a multiple application paper sheet. Zirconium Complexes act upon surface applied starch and synthetic sizes in such as manner as to make the surface of the sheet more tightly bound with surface properties needed for satisfactory ink jet printability, clean offset printing at elevated internal ash levels, and characteristics needed for other applications. Cost benefits are derived from higher CaC03 content more efficient performance of starch and synthetic sizes, fewer customer complaints, and production efficiencies from serving more end use markets with less grades.
