  Chromium-free, curable corrosion protection composition for primary coating of metallic substrates, which has a pH in the range from 1 to 3 and contains water and a) fluorocomplex ions of titanium and/or zirconium, b), at least one corrosion protection pigment, c) at least one organic polymer which is soluble or dispersible in water in the specified pH range and on its own in aqueous solution at a concentration of 50% by weight has a pH in the range from 1 to 3, process for treating metal strip with this composition and treated metal strip which can be obtained in this way. The organic polymer c) is preferably selected so that it contains at least one monomer selected from among acrylic acid, methacrylic acid, acrylic esters and methacrylic esters as free-radically polymerizable, ethylenically unsaturated monomers and has at least one type of functional groups selected from among epoxy, silane, hydroxy, carboxyl, phosphoric acid and phosphoric ester groups.
