Epoxy resin B stage film, epoxy resin curable film, and epoxy resin curable film

摘要

The epoxy resin B stage film is semi cured with an epoxy resin composition containing a liquid crystalline epoxy monomer capable of forming a curable material containing a liquid crystal structure and a curing agent, and has an average thickness of μ Less than m and curing, the liquid crystal structure contained in the cured material is a liquid crystal structure in which molecules are oriented in the film thickness direction of the film.
