RESIN COMPOSITION, AND PREPREG, SUBSTRATE AND CONDUCTIVE FOIL-CLAD SUBSTRATE, USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin composition capable of providing a substrate suitable for high-frequency application, and having excellent heat resistance; and to provide the substrate obtained therefrom.

SOLUTION: The substrate 10 in a preferable embodiment has a resin layer 12 and a fiber base material 14 arranged in the resin layer 12. The resin layer 12 comprises a cured product of a resin composition, and the resin composition comprises a resin component containing a polyvinyl benzyl ether compound, and a phosphorus compound containing a reactive phosphorus compound including a benzene ring having a phosphorus atom and a vinyl group. The total content of the phosphorus atom contained in the phosphorus compound is ≥3.5 mass% and the content of the reactive phosphorus compound based on 100 pts.mass of the resin component is ≥20 pts.mass in the phosphorus compound and the resin component respectively in the resin composition.
