Abstract
A composition for curable films, a curable film made thereof, and a cured product obtained by curing the curable film are disclosed. The curable film contains fused silica and/or hollow glass microspheres, a rubber composition containing at least one diene-based rubber, and a toluene soluble maleimide resin. The curable film is thin and has excellent processibilities. The cured product has desirable dielectric and thermomechanical characteristics that are suitable to be used as a dielectric material for printed circuit boards, especially for multilayer printed circuit boards and high-density interconnect printed circuit boards.
