Abstract
A vinyl-compound-based resin composition containing a terminal vinyl compound (a) of a bifunctional phenylene ether oligomer having a polyphenylene ether skeleton, a specific maleimide compound (b), a naphthol aralkyl type cyanate ester resin (c) and a naphthalene-skeleton-modified novolak type epoxy resin (d) for a high-multilayer and high-frequency printed wiring board, which resin composition is excellent in varnish shelf life at low temperature and does not show a decrease in multilayer moldability, heat resistance after moisture absorption, electrical characteristics and peel strength even in a winter period and for a long period of time, and a prepreg, a metal-foil-clad laminate and a resin sheet each of which uses the above resin composition.

A prepreg obtained by impregnating a resin composition into a glass woven fabric and semi-curing the resin-composition-impregnated glass woven fabric, wherein the resin composition contains a vinyl compound (a) represented by the formula (1), a maleimide compound (b) represented by the formula (5), a cyanate ester resin (c) represented by the formula (6) and an epoxy resin (d) having a repeating structure of the formula (7),
- wherein —(O—X—O)— is a structure defined by the formula (2) or the formula (3), —(Y—O)— is an arrangement of a structure defined by the formula (4) or a random arrangement of at least two kinds of structures defined by the formula (4), and each of a and b is an integer of 0 to 100, provided that at least one of a and b is not 0,
- wherein R1, R2, R3, R7 and R8 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, R4, R5 and R6 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group,
- wherein R9, R10, R11, R12, R13, R14, R15 and R16 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group and -A- represents a linear, branched or cyclic bivalent hydrocarbon group having 20 or less carbon atoms,
- wherein R17 and R18 are the same or different and represent a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group, and R19 and R20 are the same or different and represent a hydrogen atom, a halogen atom, an alkyl group having 6 or less carbon atoms or a phenyl group,
- wherein Z represents an organic group having 200 or less carbon atoms which may contain at least one member selected from the group consisting of an oxygen atom, a sulfur atom, a phosphorus atom and a nitrogen atom, and c is an integer of 2 to 20,
- wherein R represents a hydrogen atom or a methyl group and n is from 1 to 10,
- wherein R21 represents an alkyl group having 1 to 6 carbon atoms, R22 represents an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 6 carbon atoms, B is a direct bond or an alkylene group having 1 to 6 carbon atoms, and m is from 1 to 10.
