Crosslinking compositions and coatings formed therefrom

A crosslinking composition comprising:

• a compound comprising at least two functional groups that are each independently represented by Chemical Structure (I):
• X is an oxygen, sulfur, or nitrogen;
• R1 is an alkyl group, an aryl group, or an alkylaryl group;
• R2, R3, and R4 are each independently an alkyl group, an aryl group, an alkylaryl group, or a hydrogen;
• and
• R5 is an alkyl group, an aryl group, an alkylaryl group, or a hydrogen;
• z is 0 when X is oxygen or sulfur and z is 1 when X is nitrogen;
• when a double bond is formed between a carbon atom bonded to R3 and an adjacent nitrogen, m is 0, and when a single bond is formed between the carbon atom bonded to R3 and the adjacent nitrogen, m is 1;
• and
• wherein:
• (i) the compound further comprises one or more additional functional groups that are reactive with the functional groups represented by Chemical Structure (I) such that the compound is self-crosslinkable;
• and/or
• (ii) the composition further comprises a film-forming resin comprising functional groups that are reactive with the functional groups represented by Chemical Structure (I) of the compound.
