Patent ID: 8637158

Claim:
A polymerizable composition for anticorrosion coating of metallic surfaces containing components: a) at least one compound according to the following general formula (I): in which: Me represents a metal atom with an oxidation state γ, said metal atom being selected from the group consisting of silicon, titanium, zirconium, manganese, zinc, vanadium, molybdenum and tungsten; R 1 and R 2 are in each case mutually independently selected from hydrogen, C 1 -C 12 alkyl, arylalkyl groups or from the group —CO—O—W and W is in each case mutually independently a hydrogen atom, a C 1 -C 12 alkyl group or Me; R 3 corresponds to a hydrogen atom or a C 1 -C 12 alkyl group; X represents a hydrogen atom, a C 1 -C 12 alkyl, an aryl or an aralkyl group, an alkoxyl or aroxyl group or corresponds to 2(—O—X) acetylacetonate; n is 1 to γ−1 and γ denotes the oxidation state of the metal Me; Y represents an alkoxyl or polyalkoxyl group according to the following general formula (II): in which the group Y is attached via the oxo function to C c ; residues R 4 in each case mutually independently represent a hydrogen atom or a linear alkyl group with no more than 6 C atoms; and p is at least 1 but no greater than 10 and, in the event that p is equal to 1, at least one residue R 4 does not represent a hydrogen atom; and Z represents: O, NH, S, O—C(═O)—Z b —O, O—C(═O)—Z b —NH, O—C(═O)—Z b —S, O—C(═O)—Z b —C(═O)—O, O—C(═O)—Z b —P(═O)—O, O—C(═O)—Z b —P(═O) 2 —O, O—C(═O)—Z b —O—P(═O)—O or O—C(═O)—Z b —O—P(═O) 2 —O, in which Z b represents an organic group and carboxyl group —O—C(═O)— is attached to the group Y; and b) in addition to component a) at least one comonomer or cooligomer, different from a) which comprises: at least one carboxyl or an ester group; and at least one olefinic double bond.
