Abstract

Polymerizable compositions containing titanium, manganese and/or zirconium salts of olefinically unsaturated, polymerizable carboxylic acids and other olefinically unsaturated comonomers and a radical polymerization initiator are suitable for the organic coil coating of metallic materials. These non-aqueous metal coatings are suitable for the chromium-free pretreatment of steel with excellent corrosion control.
