摘要

5 ABRASION RESISTANT COATING COMPOSITIONS AND COATED ARTICLES COATING COMPOSITIONS ARE DISCLOSED THAT INCLUDE AN ALKOXIDE AND A SILICA SOL THAT INCLUDES SILICA NANOPARTICLES AND A POLYMERIZABLE (METH)ACRYLATE BINDING AGENT. THE POLYMERIZABLE (METH)ACRYLATE BINDING AGENT REMAINS SUBSTANTIALLY UNCROSSLINKED AFTER THE COATING COMPOSITION HAS BEEN CURED TO LBRM A HARD COAT. 1 5 ALSO DISCLOSED ARE ARTICLES AT LEAST PARTIALLY COATED WITH A HARD COAT DEPOSITED FROM SUCH A COATING COMPOSITION, METHODS FOR DEPOSITING A HARD COAT ON AT LEAST A PORTION OF A PLASTIC SUBSTRATE, AND METHODS FOR IMPROVING THE ADHESION AND ABRASION RESISTANCE OF A COATING COMPOSITION.
