Highly curable coating formulation for the inner surfaces of cans

The present invention relates to a water-based can inner coating based on a copolymer or a copolymer blend of at least one aliphatic and acyclic alkene having at least one ,-unsaturated carboxylic acid in water-dispersed form, wherein the can inner coating contains a water-soluble curing agent selected from inorganic compounds of the elements Zr and/or Ti, so that the need for using organic hardener systems can be largely avoided. The present invention further relates to a method for the internal coating of tin cans or aluminum cans, in which the previously mentioned can inner coating is directly applied to the metallic inner surfaces of the cans and cured without any need to carry out a conversion treatment for improving coating adhesion of the inner surfaces of the cans.
