An adhesive composition, and a coverlay film and a printed circuit board that include the adhesive composition are disclosed. The adhesive composition includes: (a) an epoxy resin; and (b) a binder resin including epoxidized polybutadiene rubber and at least two kinds of rubber. The adhesive composition can form an adhesive layer superb in terms of adhesiveness, fluidity, filling properties (landfilling), migration resistance, heat resistance, flame retardancy, low elongation, and flexibility.

Generally described herein are adhesion promoter compositions, which can be formed, for example, via a two-step synthetic process. In some embodiments, the first step of the synthetic process involves the hydrolysis and polycondensation of an organosilane monomer compound, thereby providing a polyorganosilane intermediate compound. In certain aspects, the organosilane compound may be hydrolyzed and polycondensed in the presence of a chain extender (e.g., a co-monomer) to provide an oligomeric adhesion promoter with greater degrees of functionalization. In some embodiments, the second step of the synthetic process involves the hydrosilylation of the polyorganosilane intermediate compound with a hydro silane-containing compound, resulting in a compound of the adhesion promoter.

To provide a method of producing a plate denture using a stereolithography 3D printer, which is capable of producing a plate denture in a short time with a more simplified production process, the plate denture exhibiting excellent occlusion. [Solving Means] The problem is solved by a method of producing a plate denture, including: adhering an artificial tooth and a denture base photochemically solidified by a stereolithography 3D printer to each other by polymerizing an unpolymerized curable composition for stereolithography present on a surface of the denture base. Further, stronger adhesion between the artificial tooth and the denture base is achieved by mixing, in the curable composition for stereolithography, a polymerization initiator other than a photopolymerization initiator for stereolithography.
