Corrosion-inhibiting paints and lacquers

摘要

This invention relates to corrosion-inhibiting paints and lacquers containing pigments comprising an organic corrosion inhibitor intercalated into an inorganic matrix said pigment having the formula wherein <IMAGE> wherein Me(II)O is at least one divalent metal oxide; Me(III)2O3 is at least one trivalent metal oxide; A is at least one inorganic acid anhydride; I is at least one organic corrosion inhibitor; aq is from 0.5 to 9 moles of water; and x, y and z are whole or fractional numbers and x has a value of from 0 to 1, y has a value of from 0 to 0.7 and z has a value of from greater than 0 to 0.4, with the proviso that the organic corrosion inhibitor is at least 0.5% by weight of inorganic material a process for the production of these pigments and their use in paints, lacquers and lubricants.
