<p>The invention teaches an interior coating material for container closures, having the following components: a) a polymer from the group consisting of epoxy resins based on bisphenol A diglycidyl ether or bisphenol F diglycidyl ether, epoxidized novolaks, phenol-formaldehyde condensates, acrylate resins, polyester resins and melamine resins, or a mixture of such polymers, b) a halogenated polymer from the group consisting of the polyvinyl chlorides (PVC), or a mixture of such halogenated polymers, c) a substance from the group consisting of TiO2, SiO2, FexOy and BaSO4, or a mixture of such substances, and d) a customary solvent or a mixture of such solvents. The amounts of components a), b) and c) employed are chosen subject to the proviso that the ready-to-apply interior coating material has an overall solids content of more than 40 % by weight. The proportion of the employed components b) and c) to the employed component a) is greater than 0.5 : 1. The proportion of component b) to component c) is within the range from 0.5 : 1 to 1 : 1.</p> |
