| description | PURPOSE:To obtain the title composition which is excellent in optical properties and the properties of a cured product and can easily form an optical molding by mixing a specified unrethane (meth)acrylate with a (meth)acrylate and a photopolymerization initiator in a specified ratio. CONSTITUTION:An ultraviolet-curable composition for molding an optical component comprising 100pts.wt. urethane (meth)acrylate (A) prepared from a polyol, a polyisocyanate and an active hydrogen-containing (meth)acrylate, wherein the polyol is present in the molecule in the form of a structural formula I (wherein (m) is 5-100), 50-200pts.wt. (meth)acrylate (B) of formula II (wherein R1 is H or CH3; R2 is H or 20 C or lower alkyl; A is an ethylene or propylene group; and (n) is 1-20) and 0.01-2.5pts.wt., per 100pts.wt. total of components A and B, photopolymerization initiator and having a viscosity of 300-3,000cp. This composition can easily form an optical component such as a Fresnel lens and is excellent in chemical resistance, heat resistance, cold resistance and toughness. |
