Abstract: An abrasion resistant biocidal composition is disclosed. The composition includes at least one biocidal quaternary ammonium compound, a polymeric component comprising at least one selected film-forming polymer, and at least one selected organic acid. In some embodiments, the film-forming polymer may be a polyvinylpyrrolidone or chitosan. The organic acid may be methanesulfonic acid, a selected carboxylic acid, a selected amino acid, or a combination thereof. When applied to a surface, the composition forms a film having enhanced durability without imparting poor surface feel or visual effects, and provides biocidal efficacy over an extended period of time.

Abstract: The present invention is a thermal inkjet ink that provides good reliability at a wide range of industrial print conditions from both low temperature to high temperature environments across a broad range of humidities. It is particularly advantageous in low-temperature applications, for example, printing at temperatures down to 5° C. or lower continuously for 8 hours without developing print defects which can lead to unreadable codes; and, in the meantime also maintains other critical functional aspects including contrast, wetting, decap time, dry time, adhesion, ink cartridge stability, etc. The inks contain one or more binder resins that exhibit a hydroxyl number or acid number of at least 100 mg KOH/g; one or more terpene phenolic resins; one or more volatile organic solvents; and one or more dyes, and optionally further components.
