Abstract
A polymer is provided that preferably includes at least one unsaturated cycloaliphatic group. In one embodiment, the polymer is combined with an optional crosslinker and an optional carrier to form a coating composition suitable for use in coating articles such as packaging articles. In one embodiment, the polymer has at least one unsaturated cycloaliphatic group that is at least bicyclic.
Claims24
An article comprising:
- a metal substrate of a food or beverage container or a portion thereof;
- and
- a coating applied on at least a portion of a surface of the metal substrate, wherein the coating is formed from a coating composition comprising:
- a binder polymer having:
- a Tg of at least 25° C.;
- a backbone or pendant unsaturated at least bicyclic group with a double bond located between carbon atoms of a ring, and
- an iodine value of at least about 10;
- and
- a crosslinker.

An article comprising:
- a metal substrate of a food or beverage container or a portion thereof;
- and
- a coating applied on at least a portion of a surface of the metal substrate, wherein the coating is formed from a coating composition comprising:
- a polyester binder polymer having:
- a divalent backbone segment that includes an unsaturated at least bicyclic group with a double bond located between carbon atoms of a ring, wherein the backbone segment is connected on each end to another portion of the backbone via a step-growth linkage, and
- an iodine value of at least about 10;
- and
- a resole phenolic crosslinker.
