THERMOSETTING RESIN COMPOSITION

摘要

The invention provides a thermosetting resin composition that demonstrates superior peel strength while retaining excellent heat resistance and tensile shear adhesion strength. The thermosetting resin composition comprises: an epoxy resin A containing an epoxy group and a thermoplastic resin B containing a functional group f having reactivity with an epoxy group, the thermoplastic resin B being obtained by modifying a thermoplastic resin b1 containing an unsaturated bond with a nitrone b2 containing the functional group f, and the content of the nitrone b2 relative to the unsaturated bonds being not less than 0.5 mol % and less than 10 mol %, and the content of the thermoplastic resin B being from 10 to 50 parts by mass per 100 parts by mass of the epoxy resin A.
