Abstract

A resin composition is provided. The resin composition comprises:
(A) an epoxy resin; (B) a maleimide-triazine resin; and (C) a first flame retardant having a structure of formula (I):

wherein,
Ar is a C 3 to C 18 heteroaryl or a C 6 to C 18 aryl;
R 1 is H or a C 1 to C 18 alkyl; and
R 2 and R 3 are independently H, a C 1 to C 18 alkyl, a C 3 to C 18 heteroaryl, or a C 6 to C 18 aryl.

First claim

What is claimed is:

wherein,
Ar is a C 3 to C 18 heteroaryl or a C 6 to C 18 aryl;
R 1 is H or a C 1 to C 18 alkyl; and
R 2 and R 5 are independently H, a C 1 to C 18 alkyl, a C 3 to C 18 heteroaryl, or a C 6 to C 18 aryl.

2 . The resin composition of claim 1 , wherein the weight ratio of the first flame retardant (C) to the maleimide-triazine resin (B) is 1:6 to 5:2.

3 . The resin composition of claim 1 , wherein the epoxy resin (A) is selected from the group consisting of a bisphenol epoxy resin, a phenolic epoxy resin, a diphenylethylene epoxy resin, a triazine skeleton-containing epoxy resin, a fluorene skeleton-containing epoxy resin, a triphenol methane epoxy resin, a xylylene epoxy resin, a biphenyl epoxy resin, a biphenyl aralkyl epoxy resin, a naphthalene epoxy resin, a dicyclopentadiene (DCPD) epoxy resin, an alicyclic epoxy resin, and combinations thereof.

4 . The resin composition of claim 1 , wherein the maleimide-triazine resin (B) is obtained by reacting a maleimide compound with a cyanate ester compound.

5 . The resin composition of claim 4 , wherein the maleimide compound is a bismaleimide compound.

6 . The resin composition of claim 4 , wherein the cyanate ester compound is a compound having two or more cyanate groups.

7 . The resin composition of claim 6 , wherein the cyanate ester compound is an aromatic compound having two or more cyanate groups directly bonded to aromatic ring(s).

8 . The resin composition of claim 1 , wherein the first flame retardant (C) is selected from the group consisting of
