PHENOL RESIN COMPOSITION, PREPREG AND PHENOL RESIN LAMINATE

摘要

PROBLEM TO BE SOLVED: To obtain a phenol resin composition capable of manufacturing a flame-retardant phenol resin laminate having excellent interlaminar adhesion, flexural strength and solder heat resistance without using a halogen flame retardant and even when a phosphoric ester in an amount required for providing flame retardance is used. SOLUTION: This phenol resin composition is obtained by compounding 100 pts. mass of a drying oil-modified resol type phenol resin with 25-70 pts. mass of a phosphoric ester and 2-40 pts. mass of a nonhalogen epoxy resin having >=2 reactive groups in the molecule.
