The composition contains sources of copper, zinc, and silver metal ions within a crosslinked polymer matrix. Examples of these ion sources include copper sulfate, zinc sulfate, and silver nitrate. An example of the crosslinked polymer matrix is crosslinked chitosan, which also serves to clarify the water and release the metal ions over time. The product is easy to manufacture, and allows the use of decreased halogen sanitizer, as well as decreased copper ion, thereby decreasing the likelihood of staining. The product simultaneously provides good bactericidal and algaecidal properties, despite low levels of copper ion and low chlorine levels.

Intaglio printing methods and apparatuses are disclosed, involving the use of a curable resin composition (e.g., curable by actinic radiation). The composition may be applied to a substrate, such as a printable material, at a depth of 250 μm or more, in order to create a desirable, three-dimensional effect. To produce this type of printed or coated substrate, the composition is first transferred to cells or recesses, having a depth of these dimensions, onto a printing surface (e.g., a gravure cylinder) and then at least partially cured. The at least partially cured composition is then transferred to the substrate (e.g., paper or plastic) where additional curing may occur, to produce the final printed or coated article.

Curable functionalized imide-linked polyimides compounds have been synthesized that have been found to possess very low dielectric constant and extremely low dissipation factor. These compounds also have a range of high to low modulus, extremely low moisture uptake and are very thermally stable. The combination of these materials in formulation along with functionalized polyethylene, polypropylene, polybutadiens have been found to be ideal for forming films and coatings for the microelectronic applications, multiplayer capacitors and interconnects, and high power cables and wire coatings. The addition of perfluorinated hydrocarbons, and POSS nanoparticles to the formulations have decreased the dielectric constant and dielectric dissipation factor further, and have also improved the flammability of the compositions.
