<p>A cross-linkable polymeric casting composition capable of producing an optical article exhibiting improved tint rate, the casting composition including a polyalkylene glycol diacrylate or dimethacrylate; a urethane monomer having terminal acrylic and/or methacrylic groups; and a monomer including a recurring unit derived from at least one radical-polymerisable bisphenol monomer capable of forming a homopolymer having a high refractive index; and/or a tri- or tetra-functional vinyl, acrylic or methacrylic monomer, the cross-linkable polymeric casting composition being modified to reduce the rigidity of the optical article formed therefrom, and/or increase the chemical affinity of the components of the casting composition to a dye material.</p> |
