PHOSPHORUS-CONTAINING CURING AGENT, EPOXY RESIN COMPOSITION, PREPREG, RESIN FILM WITH SUPPORT, METAL FOIL-CLAD LAMINATE AND MULTILAYER PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a phosphorus-containing curing agent capable of providing an epoxy resin composition imparted with properties including high heat resistance, flame retardancy and water resistance; and to provide an epoxy resin composition, a prepreg, a resin film with a support, a metal foil-clad laminate and a multilayer printed wiring board for a printed wiring board and using the curing agent.;SOLUTION: The phosphorus-containing curing agent is obtained by reacting a compound A represented by chemical formula (1) with a compound B having a phenolic hydroxyl group. In the formula, R¹ denotes a 0-6C hydrocarbon group, and here, the hydrocarbon group having no carbon atoms in R¹ refers to a direct bond of Cl to P. There are also provided an epoxy resin composition, a prepreg, a resin film with a support, a metal foil-clad laminate and a multilayer printed wiring board using the curing agent.;COPYRIGHT: (C)2012,JPO&INPIT
