Acetoacetylated polyvinyl polymers and curable coating compositions made therefrom

A curable coating composition comprising crosslinkable and crosslinking components wherein said crosslinkable component comprises:

• (a) an acetoacetylated polyvinyl polymer having the formula:
• wherein (m) ranges from about 1.5 mole percent to about 85 mole percent, (n) ranges from about 0 mole percent to about 20.5 mole percent, (p) ranges from about 12 mole percent to about 87 mole percent and (q) ranges from about 1 mole percent to about 88 mole percent, sum of (m), (n), (p) and (q) being 100 and wherein R1 and R2 are independently H, substituted or unsubstituted C1 to C12 alkyl, substituted or unsubstituted C6 to C14 aryl, substituted or unsubstituted C7 to C22 aralkyl, substituted or unsubstituted C6 to C14 alkaryl, substituted, unsubstituted C4 to C14 carbocyclyl or a combination thereof, said substituents being independently selected from the group consisting of C1 to C12 alkoxy, acyl, carboxyl, derivative of carboxyl, sulfonyl, derivative of sulfonyl, cyano, and halo;
• (b) an acetoacetylated polyvinyl polymer having the formula:
• wherein (m) ranges from about 1.5 mole percent to about 85 mole percent, (n) ranges from about 0 mole percent to about 20.5 mole percent, (p) ranges from about 12 mole percent to about 87 mole percent, (q) ranges from about 1 mole percent to about 88 mole percent and (x) ranges from about 0.5 to about 6 mole percent, sum of (m), (n), (p), (q) and (x) being 100 and wherein R1 and R2 are independently H, substituted or unsubstituted C1 to C12 alkyl, substituted or unsubstituted C6 to C14 aryl, substituted or unsubstituted C7 to C22 aralkyl, substituted or unsubstituted C6 to C14 alkaryl, substituted, unsubstituted C4 to C14 carbocyclyl or a combination thereof, and wherein Z is H, or —COOH and Y is —COOH, halo, unsubstituted phenyl or a combination thereof;
• said substituents being independently selected from the group consisting of C1 to C12 alkoxy, acyl, carboxyl, derivative of carboxyl, sulfonyl, derivative of sulfonyl, cyano, and halo;
• or
• (c) a combination thereof;
• and
• wherein said crosslinking component comprises a polyamine, a polyketimine, polyepoxide, polyisocyanate, melamine, C1 to C12 alkyl dialdehyde, C1 to C12 alkyl poly(meth)acrylate, or a combination thereof.
