Patent ID: 8163354

Claim:
A process for obtaining a hard coated article having anti-fouling properties comprising: a) applying onto the surface of a substrate a hard coating polymerizable composition further defined as: i) a hard coating composition A comprising: at least one silicon compound having at least one hydrolyzable group directly linked to the silicon atom and at least one epoxy group, and/or a condensation compound thereof; and at least one cationic polymerization initiator; or ii) a hard coating composition B comprising: at least one epoxy compound which is neither a hydrolysis-polymerizable silicon compound nor a condensation compound thereof; less than 5% by weight of hydrolysis-polymerizable silicone compounds and condensation compounds thereof with respect to the weight of polymerizable compounds; less than 5% by weight of silazane compounds and condensation compounds thereof with respect to the weight of polymerizable compounds; and at least one cationic polymerization initiator; or iii) a hard coating composition C comprising: at least one epoxy compound which is neither a hydrolysis-polymerizable silicon compound nor a condensation compound thereof; at least one silicon compound having at least one hydrolyzable group directly linked to the silicon atom and at least one acryloxy or alkylacryloxy group, and/or a condensation compound thereof; and at least one cationic polymerization initiator; b) activating the at least one cationic polymerization initiator to partially polymerize the hard coating composition, wherein the partial polymerization is made by polymerizing the hard coating composition in an oxygen comprising gas which partially inhibits polymerization; c) depositing onto the partially polymerized hard coating composition an anti-fouling top coat composition; d) submitting the article resulting from the preceding step to a heating step to cure the hard coating composition and the anti-fouling top coat composition; and e) recovering an article having a hard coat and an anti-fouling top coat deposited thereon and adhering to it.
