COMPOSITION FOR RUST PREVENTION AND AQUEOUS DISPERSION CONTAINING SAME

WIPO Patent Application WO/2014/034828

A1

The present invention is a composition for rust prevention, which contains: a polymer (A) that has at least a nitrile group, a hydroxyl group and an alkoxysilyl group; and a crosslinking agent (B). Specific examples of this composition for rust prevention include a composition for rust prevention, which contains: a polymer (A1) that contains a structural unit that is derived from a nitrile monomer (a-1) having an α,β-monoethylenically unsaturated group, a structural unit that is derived from a monomer (a-2) having an α,β-monoethylenically unsaturated group (excluding the above-mentioned component (a-1)), a structural unit that is derived from a monomer (a-3) having a hydroxyl group, and a structural unit that is derived from alkoxysilyl (meth)acrylate (a-4); and a crosslinking agent (B). A coating film which is obtained from this composition for rust prevention containing the polymer (A) has excellent alkali resistance, and is capable of ensuring sufficient alkali resistance even if reduced in the film thickness.
