Abstract
A composition comprising at least one curable compound (I) advantageously having a refractive index Formula (I) of at least 1.60 and obtained from the reaction of A at least one aromatic polyisocyanate, B at least one monofunctional alcohol or amine, C at least one further monofunctional alcohol or amine different from B, D at least one diol or diamine, and E optionally a hydroxyl group containing (meth)acrylate, the compound (I) comprising at least one curable functional group selected from the group consisting of carbon-carbon double bonds and epoxy groups. nD20 (I)
