PURPOSE:To provide a composition having low viscosity and excellent workability and suitable as a curable material for hermetic sealing, flame- retardant and photosetting casting material, etc., by using a photo-polymerizable compound, a bromine compound, Al(OH)3 and a photo-polymerization initiator as main components. CONSTITUTION:The objective composition is composed mainly of (A) a photosetting compound (e.g. epoxy acrylate, acrylamide, ethylene glycol diacrylate, etc.), (B) a bromine compound (e.g. tribromophenoxyethyl methacrylate), (C) Al(OH)3 and (D) a photopolymerization initiator (e.g. benzoin compound, benzophenone compound, etc.). The amounts of the components B, C and D are usually 100-250pts.(wt.), 30-150pts. and 0.1-3pts. per 100pts. of the component A.
