THERMOSETTING RESIN COMPOSITION AND PREPREG AND LAMINATE FOR ELECTRIC WIRING BOARD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a material capable of achieving flame retardance standard UL94V-0 without substantially containing a halogen or an antimony compound and a laminate scarcely causing the delamination when carrying out blanking processing. SOLUTION: This thermosetting resin composition is obtained by adding an inorganic filler in an amount of 5-250 pts.wt. based on 100 pts.wt. of a modified epoxy resin consisting essentially of (a) an epoxy resin, (b) a thermosetting resin comprising a compound having a dihydrobenzoxazine ring and (c) a polycondensate of phenols with a compound having a triazine ring and aldehydes thereto.
