Abstract
The present invention relates to a maleimide resin composition including (A) at least one selected from the group consisting of a maleimide compound having two or more N-substituted maleimide groups and a derivative thereof; and (B) a modified conjugated diene polymer, the component (B) being one resulting from modification of (b1) a conjugated diene polymer having a vinyl group in the side chain with (b2) a maleimide compound having two or more N-substituted maleimide groups and also to a prepreg, a laminate, a resin film, a multilayer printed wiring board, and a semiconductor package, each using the foregoing maleimide resin composition.
