A bisimide phenyl ester acid dianhydride represented by the following formula (2): where Rand Reach independently represents a hydrogen atom or an organic group having 1 to 10 carbon atoms; each m is independently an integer of 1 to 4; and each A independently represents an aromatic ring or an alicyclic ring.

Bisimide phenol compound

A resin composition comprising a thermosetting resin, a functional group-modified copolymer, and an inorganic filler, wherein the functional group-modified copolymer has two or more alkyl (meth)acrylate units, or one or two or more alkyl (meth)acrylate units and an acrylonitrile unit, and at least a part of alkyl ester groups of the alkyl (meth)acrylate units and/or a cyano group of the acrylonitrile unit are/is modified with at least one selected from the group consisting of an epoxy group, a carboxyl group, and an amide group.

Resin composition, prepreg, metal foil-clad laminate, and printed circuit board

The resin composition of the present invention comprises a prepolymer (P) and a thermosetting component, the prepolymer (P) being obtained by polymerizing an alkenyl-substituted nadimide (A), a maleimide compound (B), and an amino-modified silicone (C).

Resin composition, prepreg or resin sheet comprising the resin composition, and laminate and printed circuit board comprising them

The resin composition of the present invention comprises an alkenyl-substituted nadimide (A), a maleimide compound (B), and an amino-modified silicone (C).

A resin composition containing a cyclic epoxy-modified silicone compound (A) represented by formula (1), a cyanic acid ester compound (B) and/or a phenol resin (C) and an inorganic filler (D): wherein Reach independently represent an organic group having an epoxy group; Reach independently represent a substituted or unsubstituted monovalent hydrocarbon group; x represents an integer of 0 to 2; and y represents an integer of 1 to 6; and the siloxane unit marked with x and the siloxane unit marked with y are arranged mutually at random.
