To improve storage stability of a resin composition used for applications such as a semiconductor sealing material. The resin composition is a resin composition that includes (A) an epoxy resin, (B) a curing agent, and (C) a silica filler. The silica filler of component (C) is surface-treated with a basic substance having a conjugate acid dissociation constant (pKa) of 9.4 or more. The resin composition further includes (D) a silane coupling agent, or the silica filler of component (C) is further surface-treated with a silane coupling agent.

The present invention provides a composition for forming a hard coat and a laminate using the same. The composition for forming a hard coat includes at least metal oxide fine particles; a hydrolysate of an organosilicon compound; an adhesion promoting component having an alkoxysilyl group; a curing catalyst; and a solvent, wherein by introducing, as the organosilicon compound, an organosilicon compound having a hydrocarbon group having (6 to 18) carbon atoms substituted with a glycidoxy group, and an organosilicon compound having a hydrocarbon group having (1 to 5) carbon atoms substituted with a glycidoxy group, even when applied to a flexible resin substrate, the composition for forming a hard coat has excellent adhesion and scratch resistance, and bending resistance (crack resistance) and surface hardness as well.
