PROBLEM TO BE SOLVED: To provide a gel coat which comprises a radical-polymerizable thermosetting resin excellent in the adherence to an epoxy resin and is suitable for an FRP made by using an epoxy resin as its matrix. SOLUTION: The gel coat for an epoxy resin comprises essentially (A) a polyfunctional radical-polymerizable compound, (B) a monofunctional radical- polymerizable compound having neither epoxy group nor acid anhydride group, and (C) a monofunctional radical-polymerizable compound having an epoxy group and/or an acid anhydride group.
