Abstract
Abstract The invention is directed to curable compositions comprising an azole-functional resin and a labile metal-ligand complex. The azole-functional resin is the reaction product of a monomeric or polymeric resin and a reactive N-heterocyclic compound containing at least two nuclear nitrogen atoms in a 5-membered ring structure capable of forming stable metal-ligand complexes. Mixtures of azole-functional resins also may be used with the labile-metal ligand complexes in the compositions of the invention.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
27 words
A curable composition comprising: (A) an azole-functional resin; and (B) a labile metal-ligand complex; wherein said labile metal-ligand complex is capable of reacting with said azole-functional resin.
Claim 2
Dependent Claim
27 words
A curable composition comprising: (A) an azole-functional resin; and (B) a labile metal-ligand complex; wherein said labile metal-ligand complex is capable of reacting with said azole-functional resin.
Claim 3
Dependent Claim
31 words
The composition of claim 1 wherein the azole of said azole-functional resin is selected from the group consisting of an imidazole, a triazole, a tetrazole, a thiadiazole and a mixture thereof.
Claim 4
Dependent Claim
26 words
The composition of claim 1 wherein the ratio of equivalents of said labile metal-ligand complex to said azole-functional resin is from about 0.5:1.0 to about 2.0:1.0.
Claim 5
Dependent Claim
45 words
The composition of claim 1 wherein said azole-functional resin comprises the reaction product of (i) a compound selected from the group consisting of a triazole, a thiadiazole, a tetrazole, an imidazole, and a mixture thereof; and (ii) a resin capable of reacting with said compound.
Claim 6
Dependent Claim
28 words

Claim 7
Dependent Claim
28 words
The composition of claim 4 wherein said compound is a thiadiazole substituted by a primary amino, secondary amino or mercapto group on at least one nuclear carbon atom.
Claim 8
Dependent Claim
26 words
The composition of claim 4 wherein said compound is a tetrazole substituted by a primary amino, secondary amino or mercapto group on the nuclear carbon atom.
Claim 9
Dependent Claim
