Abstract:
The invention is directed to a conversion coating composition for coating a metal surface including a water soluble dye, at least one metal compound selected from the group consisting of a zirconium-containing compound, titanium-containing compound and silicon-containing compound; and water, wherein the provides for qualitative characterization of the conversion coating uniformity and thickness by the naked human eye or visible light detecting device; and, a method for coating the metal surfaces using the conversion coating composition.

Claim (Index 37):
A conversion coating composition comprising:\n ( 1 ) at least one metal corrosion inhibitor compound, wherein the at least one metal corrosion inhibitor is a zirconium-containing compound having the structure of formula (III):\n [ZrL 1 4 ] b  \n wherein each occurrence of L 1  is independently NO 3 \u2014, \u2014F, [\u2014O\u2014] 1/2 , [\u2550O] 1/2  or \u2014OR 4 , where each occurrence of R 4  is independently selected from the group consisting of acetyl, alkyl, cycloalkyl, aryl, aralkyl, alkoxy-substituted alkyl and hydroxyl-substituted alkyl groups containing up to about 16 carbon atoms and hydrogen; and the subscript b is an integer of from 1 to 100, more specifically 1 to 15, and even more specifically 1, with the provisos that (a) when L 1  is [\u2550O] 1/2 , then a second L 1  group is a [\u2550O] 1/2  group, which is bonded to the same zirconium atom having the structure [\u2550O] 1/2 , and the two L 1  having the structure [\u2550O] 1/2  are combined to form a double bond between the oxygen and zirconium atom; and (b) when c is equal to or greater than 2, then at least one L 1  in each repeat unit [ZrL 1 4 ] is a [\u2014O\u2014] 1/2  group and each [\u2014O\u2014] 1/2  in the repeat unit is combined with another [\u2014O\u2014] 1/2  group in a different repeat unit to form a Zr\u2014O\u2014Zr bond which links the repeat units together; or is at least one titanium-containing compound having the structure of formula (IV):\n [TiL 2 4 ] c  \n wherein each occurrence of L 2  is independently NO 3 \u2014, \u2014F, [\u2014O\u2014] 1/2 , [\u2550O] 1/2  or \u2014OR 5 , where each occurrence of R 5  is independently selected from the group consisting of acetyl, alkyl, cycloalkyl, aryl, aralkyl, alkoxy-substituted alkyl and hydroxyl-substituted alkyl groups containing up to about 16 carbon atoms and hydrogen; and the subscript c is an integer of from 1 to 100, more specifically 1 to 15, and even more specifically 1, with the provisos that (a) when L 2  is [\u2550O] 1/2 , then a second L 2  group is a [\u2550O] 1/2  group, which is bonded to the same zirconium atom having the structure [\u2550O] 1/2 , and the two L 1  having the structure [\u2550O] 1/2  are combined to form a double bond between the oxygen and titanium atom; and (b) when c is equal or greater than 2, then at least one L 2  in each repeat unit [TiL 2 4 ] is a [\u2014O\u2014] 1/2  group and each [\u2014O\u2014] 1/2  in the repeat unit is combined with another [\u2014O\u2014] 1/2  group in a different repeat unit to form a Ti\u2014O\u2014Ti bond which links the repeat units together; or, mixtures thereof; (ii) water; and, (iii) at least one water soluble dye such that when the conversion coating composition is applied to a metal surface, the dye is visible to the naked eye and/or its presence is detectable and its intensity is measurable by optical instrumentation.
