Abstract: The coating composition according to the invention comprises:(A) a component which is the reaction product with oxalic acid of at least one organometallic compound of formula:wherein, M is a metal R is H or an alkyl radical, R is a chelating ligand, x is the valency of the metal, y is an integer at least equal to 1 and x-y is at least equal to 1; and(B) at least one organoalkoxysilane of formula:wherein, R is an alkyl radical, R is an epoxidized alkyl group and n is an integer from 1 to 3 or a mixture of the organoalkoxysilane of formula (II) with an alkoxysilane of formula (II')wherein n' is an integer from 0 to 3,R'' is H, an alkyl radical or an alkoxyalkyl radical, andR' is a vinyl, (meth)acryl, aromatic, cyclic or aliphatic alkyl radical.
