RESIN COMPOSITION, RESIN VARNISH, PREPREG, METAL-CLAD LAMINATE, AND PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a resin composition having excellent dielectric properties, which a polyarylene ether copolymer has, and excellent moldability, heat resistance and flame retardancy, which a sulfide has.

SOLUTION: The resin composition contains: a polyarylene ether copolymer of which intrinsic viscosity measured in a methylene chloride at 25°C is 0.03-0.12 dl/g, wherein the average number of phenolic hydroxyl groups per one molecule at the terminal of each molecule is 1.5-3; an epoxy resin of which solubility to toluene is ≥10 mass% at 25°C; a curing accelerator; an inorganic filler; and a dispersant having a phosphoric acid group in a molecule.
