RESIN COMPOSITION, PREPREG AND LAMINATE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a resin composition having high glass transition temperature, low dielectric constant and high peel strength.SOLUTION: In a resin composition, epoxy resin and monofunctional anhydride are mixed so that an equivalent ratio of the epoxy resin and the monofunctional anhydride is 1:0.5 to 1.5. The resin composition includes a preliminary reaction product preliminary reacted the epoxy resin and the monofunctional anhydride so that a ring opening rate of the monofunctional anhydride is 10% or more and less than 65%.
