Abstract:
An optical-quality plastic part is provided having a PET polarizing film integrally bonded thereto and, optionally, a hard coating integrally bonded to the PET polarizing film. In a preferred construction, the film may be surface treated, either physically and/or chemically, for integrally bonding the film to the optical-quality plastic material. Similarly, in another preferred construction, the film may be physically and/or chemically surface treated for integrally bonding a hard coating to the PET film. In either construction, the treatment may be effected by light irradiation.
