Abstract
Disclosed are radically polymerisable compositions which contain at least one monofunctional monomer and at least one difunctional monomer; resins which are obtainable by radical copolymerisation of said compositions, it being possible for the resins to be photochromic or not; articles, notably ophthalmic articles, which are constituted totally or in part of such resins; and new monofunctional monomers.
