Maleimide resin mixture, curable resin composition, varnish, and cured product thereof

Abstract

The present invention provides: a maleimide resin mixture having an excellent low dielectric loss tangent and excellent storage stability in varnished form; a curable resin composition; and a cured product thereof. The maleimide resin mixture comprises: a maleimide resin having repeating units represented by formulas (a) and (b); and bis(3-ethyl-5-methyl-4-maleimidephenyl)methane represented by formula (c), wherein the content of the bismaleimide represented by formula (c) in the total amount of the maleimide resin mixture is 5.0-30.0 area % in terms of GPC area percentage. In the formulas, m is the average number of repetitions and is 0<m<200. n is the average number of repetitions and is 0<n<100. (a) and (b) are each bonded at *, and repetition positions may be random.
