摘要：
The present invention is directed to coatings that provide improved retort and tropical decay resistance for use on metal food containers. The coatings generally comprise a carbamated polyol formed by the reaction between a polyol, an alkylene oxide and an alkyl carbamate. A crosslinker reactive with the carbamate functionality is used to react with the carbamate moiety. Methods for improving retort resistance and resistance to tropical decay are also disclosed, as are substrates coated with the present compositions.
