A thermosetting epoxy resin composition comprising (A) a reaction mixture of a triazine derivative epoxy resin and an acid anhydride at a ratio of the epoxy group equivalent to the acid anhydride equivalent of 0.6 to 2.0; (B) an internal mold release agent; (C) a reflective material; (D) an inorganic filler; and (E) a curing catalyst. The internal mold release agent of component (B) comprises a carboxylate ester represented by:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 11 -COO-R 12 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein R 11 and R 12 are C n H 2n+1 , and n is 1 to 30 and a compound represented by:
wherein R 1 , R 2 , and R 3 are selected from H, -OH, -OR, and -OCOC a H b with the proviso that at least one includes -OCOC a H b ; R is C n H zn+1 (wherein n is an integer of 1 to 30), a is 10 to 30, and b is 17 to 61. |
