A transparent molded article comprised of a polymer of the following components (A) and (B), characterized in that said polymer further comprises the following components (C) and (D). A transparent molded article comprised of a polymer of the following components (A) and (B), characterized in that said polymer further comprises the following component (G). An optical member comprising an antireflective layer directly or indirectly on a polyurethane urea polymer substrate, characterized in that said antireflective layer is a multilayer antireflective layer comprising a ½ lambda layer, and said ½ lambda layer comprises a plural high refractive index layers comprising niobium oxide or niobium oxide, zirconium oxide and yttrium oxide, and a layer comprised of silicon dioxide positioned between the high refractive index layers. Component (A): isocyanate terminal prepolymer in the form of a reaction product of an aliphatic diisocyanate having an intramolecular cyclic structure and a diol having an average molecular weight of 300-2,500 Component (B): one or more aromatic diamines denoted by general formula (I). (In general formula (I), R1, R2 and R3 are each dependently any of a methyl, ethyl or thiomethyl group.) Component (C): one or more phosphoric acid monoesters denoted by general formula (II). (In general formula (II), R4 is an alkyl group with a carbon number of 1-10 and n1 is 1 or 2.) Component (D): one or more phosphoric acid diesters denoted by general formula (III). (In general formula (III), R5 and R6 are each dependently an alkyl group with a carbon number of 1-10 and n2 and n3 are 1 or 2.) Component (G): one or more phosphorous peroxide decomposing agents.
