Abstract
Abstract Plastisols based upon plasticizable polyvinyl chloride, or co-polymers of vinyl chloride, and plasticizers, as well as a content of polymerizable esters of α,β-unsaturated carboxylic acids and polyhydroxy alcohols, and solid inorganic percompounds, which can be used for the production of firmly adhering coatings and adhesives.
