The present invention discloses a thermoset resin composition including epoxy resin other than brominated epoxy resin, styrene maleic anhydride copolymer and additive-type flame retardant. The thermoset resin composition also includes an active ester. The thermoset resin composition is used to prepare resin sheet, resin coated copper, prepreg, laminate, copper clad laminate and printed wiring board, and so on. Said thermoset resin composition remarkably reduces the probability of delamination for the PCB laminate, and overcomes drawback of the tetrabromobisphenol A to introduce dielectric properties which will deteriorate the system. The obtained resin composition has good thermal stability and moisture-heat resistance, low dielectric constant and dielectric loss angle tangent, and good flame resistance. |
