Abstract
A laminate body is provided, in which two or more organopolysiloxane cured films are obtained by curing curable organopolysiloxane compositions having different compositions because, e.g., the functions required for a dielectric layer and electrode layer are different. In general, problems such as peeling and defects due to insufficient adhesive strength and trackability do not easily occur at an interface between the cured films forming the laminate body. Applications and methods are also provided. The laminate body comprises a structure with two or more laminated organopolysiloxane cured films with different compositions. At least a portion of functional groups involved in the curing reaction are the same. The laminated cured films have structures chemically bonded at an interface thereof. Typically, the compositions both contain a hydrosilylation reactive group, and a SiH/Vi ratio in the compositions differ, with the laminated cured films having structures chemically bonded by hydrosilylation reactions at an interface thereof.
