Abstract
The invention provides an abrasion resistant coating composition for an optical element. The composition includes a polymerisable epoxy monomer having an average of at least two epoxy groups in the monomer molecule. The composition is capable of forming an abrasion resistant coating on an optical element after ionic polymerisation. The coating composition may also include an ionically polymerisable alkene monomer having an average of at least two polymerisable double bonds in the molecule.
