Abstract: A corrosion inhibitor is described which includes several supramolecular oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions preferably include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.

Abstract: Modern techniques for manufacturing paper using mechanical wood pulp has lead to a persistent over-acidification of printed manner, and threatens to permanently destroy the same.

Abstract: Individual compounds that provide effective toning (or bluing) to combat yellowing within polyester articles (such as bottles, containers, and the like) are provided. Such a novel toner permits effective neutralization of yellowness while also providing highly desirable low haze and increased brightness due to a sharp absorption peak within the needed range of wavelengths (e.g., from about 565 to 590 nm) and a narrow half-height band width. Furthermore, such an individual compound is preferably liquid in nature and may thus be incorporated within an added ultraviolet absorber solution or shelf-stable dispersion to facilitate addition within target polyesters at various stages of production. The particular UV absorbers desired as additives within target polyesters also tend to exhibit certain yellowing effects that require attention as well. The inventive single bluing agent compound thus also accords effective neutralization of such UV absorber yellowing as well.
