Abstract

PURPOSE: To obtain a laminated sheet excellent in moisture resistance, electrical insulation and heat resistance, by using prepregs obtained by impregnating base sheets with an epoxy resin containing a novolak type phenol resin.
CONSTITUTION: A novolak type phenol resin, content of unreacted phenol ≥1%, is used as a curing agent. Prepregs are obtained by impregnatong base sheets with an epoxy resin composition containing the above phenol resin in an amount to provide 0.5W2eq. of phenolic OH groups participating in the reaction, per eq. epoxy group, and driving the impregnated sheets. Parr or all of the prepregs are laminate- molded. In the above laminating epoxy resin a resin containing the phenolic OH groups in an amount of below 0.5 or above 2 is not preferred because such conditions prolong the curing time of the varnish and cause considerable boiling degradation.
