To provide a transparent polyimide-silica hybrid cured product or multilayered product with excellent adhesivity and insulating property.
This silane-modified polyamic acid resin composition comprises an alkoxy group-containing silane-modified polyamic acid obtained by reacting a polyamic acid(1) having a diamine residue with a benzoxazole skeleton and an epoxy group-containing alkoxysilane partial condensate(2) obtained by dealcoholization reaction of an epoxy compound(A) having one hydroxy group in a molecule with an alkoxysilane partial condensate(B), and a polar solvent. The silane-modified polyamic acid resin composition is made into a surface coating agent by coating, etc., to be multilayered on a film or substrate each with a specific coefficient of linear expansion.
