<P>PROBLEM TO BE SOLVED: To provide a thermosetting epoxy resin composition giving a cured product which has a high initial reflectance and good shielding properties, retains reflexivity, heat resistance and light resistance for a long period, is uniform and hardly turns yellow. <P>SOLUTION: The thermosetting epoxy resin composition contains, as essential components: (A) a triazine derivative epoxy resin; (B) a curing agent; (C) an antioxidant; (D) an internal release agent having a melting point in the range of 50-80°C; (E) a reflection improver having a lead content of <10 ppm on a mass basis; (F) an auxiliary flame retardant; (G) an inorganic filler; and (H) a curing catalyst; wherein with respect to 100 parts in total of (A) and (B), (C), (D), (E), (F), (G) and (H) are contained in amounts of 0.02-5.0 parts, 0.2-10.0 parts, 50-1,000 parts, 2.0-100 parts, 50-1,000 parts and 0.05-5.0 parts, respectively, and wherein the molar ratio of epoxy groups of the epoxy resin of (A) to reactive groups of epoxy groups contained in the curing agent of (B) fulfills (epoxy groups)/(reactive groups of epoxy groups)≥1.0. <P>COPYRIGHT: (C)2012,JPO&INPIT |
