ABSTRACT:
An allyl ester oligomer composition having a viscosity of 200 to 50,000 cP at 30.degree. C. and a refractive index of 1.50 to 1.57 at 30.degree. C., which is formed by mixing (a) 20 to 90% by weight of an allyl ester oligomer, (b) 10 to 80% by weight of at least one polyvalent allyl ester monomer selected from the group consisting of diallyl phthalate, diallyl isophthalate, diallyl terephthalate, diallyl adipate, triallyl (iso)cyanurate and triallyl trimellitate, and (c) up to 40% by weight of at least one monofunctional polymerizable monomer selected from the group consisting of vinyl benzoate, allyl benzoate, phenyl (meth)acrylate and benzyl (meth)acrylate.
