Document Type and Number:
Japanese Patent JP5675698
Kind Code:
B2
Abstract:
A flame retardant phosphorus element-containing epoxy resin composition substantially free of halogen, including:(I) a non-halogenated epoxy resin material selected from:(A) a non-halogenated phosphorus element-containing epoxy resin;(B) a mixture of:(1) a non-halogenated, non-phosphorus element-containing epoxy resin, and(2) a phosphorus element-containing compound; or(C) the reaction product of:(1) a non-halogenated epoxy resin; and(2) a phosphorus element-containing compound; or(D) a combination of two or more of components (A) to (C); and(II) (A) a multi-functional phenolic crosslinking agent having a hydroxy functionality of at least 2; (B) a material which forms a multifunctional phenolic crosslinking agent having a hydroxy functionality of at least 2, upon heating or (C) a mixture of components (A) and (B); in an amount of from about 50% to about 150% of the stoichiometric amount needed to cure the epoxy resin. Electrical laminate circuit boards having reduced flammability may be made from these compositions.
