ABSTRACT:
A thermosetting resin composition is provide, which contains a compound of ##STR1## wherein substituents R.sub.1 -R.sub.6 each represents a hydrogen atom or a saturated alkyl group having 1-6 carbon atoms, substituents R.sup.7 -R.sup.12 each represents a hydrogen atom, a saturated alkyl group having 1-4 carbon atoms or an alkoxy group having 1-4 carbon atoms, X.sub.a -X.sub.e each represents a hydrogen atom, a chlorine atom or a bromine atome, and the average repeating unit number n denotes a numeral from 0 to 5, and a polyamide compound having two or more maleimide groups and, if desired, a compound of ##STR2## wherein R.sub.1 and R.sub.2 each represents a methyl group or a phenyl group, and R.sub.3 represents a hydrogen atom or a functional group containing an amino group, a glycidyl group or an alicylic epoxy group, l denotes a numeral in the range of 0-500, and m denotes a numeral in the range of 1-500, or ##STR3## wherein R.sub.1 and R.sub.2 each represents a methyl group or a phenyl group, and R.sub.3 represents a hydrogen atom or a functional group containing an amino group, a glycidyl group or an alicyclic epoxy group, and p denotes a numeral in the range of 0-500. The composition is useful for electronic parts.
