70?? C., and even more preferably at least 80?? C. In preferred embodiments, the Tg is less than 150?? C., more preferably less than 130?? C., and even more preferably less than 110?? C. While not intending to be bound by any theory, it is believed that it is especially important that the polymer exhibit a Tg such as that described above in applications where the coating composition will be in co
