Abstract
Abstract A vinylidene chloride copolymer coating composition containing small amounts of a polybasic acid of phosphorus, such as orthophosphoric acid, or sulfuric acid, in combination with a mono- or diglyceride. Organic polymeric films, such as polyester and regenerated cellulose films, coated therewith exhibit excellent antistatic properties. Such coated films can be run on various types of machinery without problems due to static build-up.
