Abstract

A cured material of a curable composition comprising (1) an organic elastomeric polymer having at least one silicon-containing group to the silicon atom of which a hydroxyl group and/or a hydrolyzable group are bonded and which is cross linkable through formation of a siloxane linkage in a molecule, (2) an epoxy resin, (3) a curing agent for the epoxy resin and (4) a curing catalyst for the organic elastomeric polymer is firmly adhered to a substrate when a vinyl type polymer having at least one silicon-containing group to the silicon atom of which a hydroxyl group and/or a hydrolyzable group are bonded and which is cross linkable through formation of a siloxane linkage is coated on a substrate before application of the curable composition.
