THERMOSETTING RESIN COMPOSITION AND PREPREG AND SUBSTRATE PRODUCED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a thermosetting resin composition having excellent dielectric properties in a high-frequency band range and various material characteristics such as high adhesiveness, low cost and good processability and provide a prepreg and a substrate produced by using the composition. SOLUTION: The thermosetting resin composition contains a vinylbenzyl compound and a polyvalent oxazine compound having multiple dihydrobenzoxazine rings in the molecule. The prepreg is produced by impregnating the thermosetting resin composition in a glass cloth and the ratio of the glass component in the prepreg is 10-70 wt.%. The substrate is produced by laminating the prepreg and a metal foil. COPYRIGHT: (C)2005,JPO&NCIPI
