Solvent-based double-package anticorrosive coating composition

The present invention relates to a solvent-based dual packaging coating composition comprising (A) a masterbatch composition comprising (a) one or more polymers and/or resins reactive against one or more cross-linking agents contained in hardener component (B), (b) one or more pigments and/or fillers and (c) one or more substances selected from the group consisting of substances of formula (II), wherein two of the four residues R1 are OH and the other two residues R1 are H; r < 2 > = O, R < 3 >-R < 4 > are C = C or HC-CH, R < 5 > is p-(OH) Ph (R7) (R8), R < 6 > = H or OH, R < 2 > = O, and R < 7 > and R < 8 > are H or OH, with the proviso that at least one of R < 7 > and R < 8 > is H; and/or a substance of formula (III) wherein R1 is as described above and R2 is C = O; (B) a hardener composition comprising one or more cross-linkers comprising functional groups that are reactive to functional groups of the one or more polymers and/or resins; and optionally, (C) a diluent composition.
