Abstract

Provided are curable resin compositions capable of giving cured articles that have high light reflectivity, are satisfactorily resistant to heat and light, are tough, and less suffer from light reflectivity reduction with time. A curable resin composition for light reflection includes an alicyclic epoxy compound (A), rubber particles (B), a white pigment (C), a curing agent (D), and a curing accelerator (E). Another curable resin composition for light reflection includes an alicyclic epoxy compound (A), rubber particles (B), a white pigment (C), and a curing catalyst (F).
