Claim:
A composition prepared by reacting: at least one compound (A) selected from the group consisting of low molecular mass, oligomeric and low molecular mass, polymeric compounds, each of said compounds having at least two epoxide groups (a1), and at least one silane (B) comprising at least one radical (b1), having a valency of at least two, that is not hydrolyzable, at least one cyclic dicarboxylic anhydride group (b2) and at least one silane group (b3) comprising three hydrolyzable groups (b31), wherein the at least one cyclic dicarboxylic anhydride group (b2) is attached to the at least one silane group (b3) by the at least one radical (b1), and the equivalent ratio of epoxide groups (a1) to the at least one dicarboxylic anhydride group (b2) is 0.7 to 100.
