Abstract
A thermosetting resin composition comprising: (1) a copolymer resin comprising (a) a monomer unit and (b) a monomer unit respectively represented by the following general formulae (I) and (II):wherein R1 represents hydrogen, a halogen, or a C1–C5 hydrocarbon group; R2 represents a halogen or a C1–C5 hydrocarbon group; x is 0 to 3; and each of m and n is a natural number; and (2) a cyanate resin having at least two cyanate groups per molecule; is used to provide a printed wiring board material and a printed wiring board for electronic appliances, having a low dielectric constant and a low dielectric dissipation factor as well as improved heat resistance.
