A coating composition suitable for providing a hardcoat comprising a topcoat and an epoxy modified adhesion promoter. The epoxy modified adhesion promoter comprises, in one embodiment, a molecule with the formula (1): U-Q-R1-SiR2 gR3 (3-g) wherein Q is -CH2CH(OH)CH2-O- or -CH2CH(OH)CH2-NR4-; U is: -O-(C6HhR2 (4-h)-CR5-C6HhR2 (4-h)-O-H2CH(OH)CH2-O)i-C6HhR2 (4-h)-CR5-C6HhR2 (4-h)-O-J; where R2 is chosen from a C1-C 10 alkyl or a substituted or unsubstituted phenyl group; R3 is chosen from an alkoxy, an acetoxy, or a ketoxime radical; R1 is a C1-C4 alkylene; g is 0-2; h is 0-4; R4 is hydrogen or -CH2CH(OH)CH2-U-; R5 is hydrogen or an alkyl; i is 0-100; and J is H, Q-R1SiR2 hR3 (3-h), or formula (2). The coating composition is suitable for application to a substrate without the use of a primer. |
