| abstract |
The present invention provides radiation-curable compositions for coating plastic substrates, wherein the compositions, after cure, have a combination of sufficient adhesion, flexibility, and hardness. The compositions include: (a) at least one component comprised of a metal oxide bonded to an organic compound, said organic compound having (i) a radiation curable group; and (ii) a group represented by the following formula (1) wherein X represents an amine (NH), oxygen (O), or sulfur (S) radical; and Y represents an oxygen (O), or sulfur (S) radical; (b) a poly(methacrylate) compound; and (c) an adhesion promoter. |
