Claim Text:
1. A corrosion inhibiting pigment comprising nanoscale reservoirs (nanoreservoirs) of corrosion inhibitor for active corrosion protection of metallic products and structures comprising an active constituent consists essentially of the corrosion inhibitor, wherein, the nanoreservoirs have average dimensions of 1-1000 nm and comprise a polymer or polyelectrolyte shell sensitive to a selected trigger and releases said inhibitor after action of said trigger, 2) each of the nanoreservoirs has an individual polymer or polyelectrolyte shell, 3) the nanoreservoirs are selected from the group consisting of hollow polyelectrolyte capsules, hollow polymer capsules, nanotubes, halloysites, and hollow or porous nanoparticles coated with the polymer or polyelectrolyte shell, 4) the corrosion inhibitor is incorporated exclusively in cavities or pores of said nanoreservoirs.
