Abstract
A resin composition includes (A) a polyolefin epoxy resin, (B) an epoxy resin having a condensed polycyclic aromatic hydrocarbon, (C) a nitrogen-containing novolak resin, and (D) an inorganic filler, in which an epoxy equivalent of the (A) component is 200 g/eq. or more, a nitrogen content in the (C) component is 13% by mass or more and/or the (C) component has a cresol novolak structure, and a content of the (D) component is 60% by mass or more on the basis of 100% by mass of non-volatile components in the resin composition.
Claims13
A resin composition, comprising:
- (A) at least one polybutadiene epoxy resin;
- (B) at least one epoxy resin having one or more naphthalene rings and two or more epoxy groups in one molecule;
- (C) at least one triazine-containing novolak resin having a cresol novolak structure;
- and
- (D) at least one silica, wherein
- an epoxy equivalent of said (A) at least one polybutadiene epoxy resin is 200 g/eq. or more and 250 g/eq. or less,
- a nitrogen content in said (C) at least one triazine-containing novolak resin having a cresol novolak structure is 16% by mass or more and 22% by mass or less,
- a content of said (A) at least one polybutadiene epoxy resin is 1.5% by mass or more and 10% by mass or less based on 100% by mass of non-volatile components in said resin composition,
- a content of said (B) at least one epoxy resin having one or more naphthalene rings and two or more epoxy groups in one molecule is 5% by mass or more and 20% by mass or less based on 100% by mass of non-volatile components in said resin composition,
- a content of said (C) at least one triazine-containing novolak resin having a cresol novolak structure is 0.5% by mass or more and 10% by mass or less based on 100% by mass of non-volatile components in said resin composition, and
- a content of said (D) at least one silica is 60% by mass or more and 90% by mass or less based on 100% by mass of non-volatile components in said resin composition.
