Abstract
A substrate at least partially coated with an anti-fingerprint coating is prepared from a coating composition that includes: (a) an organic solvent; and (b) an alkoxysilane functional polymer having at least one ester linkage, at least one urethane linkage, and at least one alkoxysilane functional group. Further, the polymer is prepared from components including: (i) an active hydrogen functional compound having a hydroxyl group, amino group, thiol group, or a combination thereof; (ii) an intramolecular cyclic ester; and (iii) an isocyanate functional compound. The active hydrogen functional compound (i), the isocyanate functional compound (iii), or both (i) and (iii) have one or more alkoxysilane functional groups. Alkoxysilane functional polymers and coating compositions containing the same are also included.
