CURABLE COMPOSITION AND CURED PRODUCT THEREOF

摘要

The object is to make a curable composition formulatable into a one-component type having excellent storage stability. Disclosed is a curable composition comprising (A) a compound having a carboxyl group, (B) an epoxy resin, (C) an acid, (D) a ketone-type solvent, (E) a photosensitive (meth)acrylate compound and (F) a photopolymerization initiator. When a photosensitive compound having a carboxyl group is used as the component (A), the component (E) (i.e., a photosensitive (meth)acrylate compound) can be eliminated. The epoxy resin (B) comprises at least one component selected from the group consisting of (B-1) an epoxy resin having two or more epoxy groups per molecule and (B-2) an epoxy resin having a 1,3-dioxolane ring which can be produced by performing a partial addition reaction of a ketone to an epoxy resin having two or more epoxy groups per molecule.
