Optically brightened aqueous compositions

An aqueous composition that includes an optical brightener (e.g. a UV-fluorescent compound) and forms a coating when applied to an array of surfaces. The coating may be applied to polyester shrink wrap film making the film tamperproof when applied as packaging or over packaging closures. A method of...
