PURPOSE:A composition excellent in photocurability, coating quality, etc., obtained by mixing a compound containing an epoxy group and a photocurable unsaturated double bond with an organometallic compound, a silicon compound which generates silanol groups upon irradiation with light and a surfactant. CONSTITUTION:The purpose photocurable composition is obtained by mixing a compound (A) having at least one epoxy group and at least one photocurable unsaturated double bond in one molecule (e.g., acrylated epoxy resin) with an organometallic compound (B), e.g., trismethoxyaluminum, a silicon compound (C) which generates silanol groups upon irradiation with light (e.g., formula I or formula II), a surfactant (D) (e.g., formula III or tetramethyldisiloxane) and, optionally, a sensitizer and necessary additives such as a metal naphthenate. This composition is excellent in the homogeneity, smoothness, etc., of a film and can be suitably used for paints, inks, sealants, etc.
