ABSTRACT:
A composition comprising a varnish of heat-resistant resin having active hydrogen in the molecule and a bismaleimide compound or derivative thereof admixed with the varnish affords a heat-resistant resin product of improved properties. Especially when a bismaleimide compound or derivative thereof is added to a varnish of polyimide resin having active hydrogen in the molecule and the composition is applied to a metal film substrate to form a resin film, the film has improved peel strength and, in itself, also has improved strength and elongation.
