Glass fiber-reinforced electrical laminates and a continuous production method therefor

摘要

There is provided an electrical laminate comprising a cured assemblage of a plurality of glass fiber type substrates impregnated with a curable resin composition containing (a) a halogenated bisphenol type unsaturated polyester resin and (b) an epoxy acrylate resin which may optionally be halogen-containing. This laminate features high dimensional stability, improved through-hole reliability, and excellent mechanical strength. A continuous production method for laminates is also described.
