Abstract: Manufacturing technologies for making interactive paper have been steadily improving and have satisfied most present-day requirements of printers and other consumers. Features such as paper composition, color, texture, strength and chemical stability have been optimized through increased understanding of the chemical interactions between the raw material and additives. However, next generation higher-speed printing machines, the public's desire to read higher resolution print, and the need for better security papers are challenging chemists to develop new fillers for inks and paper. The latter are often dispersions of fine particles in a liquid or cellulose matrix. This presentation summarizes advances being made in the author's laboratory for preparing new and unique colloidal and coated particles having potential use by the paper and printing industry. !15
