Abstract:
Disclosed is a process for molding plastic optical articles with a hard coated film, comprising steps of coating one side of an optical film with a hard coating, pre-curing the hard coating to a tack free state while still maintaining the coating flexibility, making an insert from the coated film for the desired optical article, molding the plastic resin onto the insert through insert injection molding, and post-curing the molded article. The utilization of the pre-curing and post-curing steps have been found to eliminate hard coating cracks during the insert making and the molding step, while providing a hard coating with desired properties. Such an optical article possesses a hard coating integrated on its surface, thus, eliminating the need to further coat the optical article.
