Abstract:
1. A resin composition containing: 100 parts by weight of a thermosetting resin being at least one selected from the group consisting of an epoxy resin, a thermosetting modified polyphenylene ether resin, a thermosetting polyimide resin, a silicone resin, a benzoxazine resin, and a melamine resin; 0.1-65 parts by weight of an inorganic compound; and one or more curing agents, catalysts or initiators, as required to increase the molecular weight of the thermosetting resin and finally form a cured product of the resin composition having a three-dimensional network structure, wherein said inorganic compound comprises a layered silicate being dispersed in the thermosetting resin such that stacks of the layered silicate have a mean interlayer spacing of between 3 to 5 nm along (001) plane within said cured product; and wherein said cured product has a mean linear expansion coefficient (α2) of up to 17×10
